MS3110 Universal Capacitive Readout TM IC Description:The Universal Capacitive Readout TM IC (MS3110) is a general purpose, ultra-low noise CMOS IC intended to support a variety of MEMS sensors that require a high resolution capacitive readout interface. The MS3110 requires only a single +5VDC supply and some decoupling components. No additional components are required.MEMS sensors (such as accelerometers, rate sensors, and other sensors that can be modeled as variable capacitors) require a readout electronic interface that can sense small changes in capacitance. TheMS3110 is capable of sensing capacitance changes down to 4.0 aF/rtHz, typical.The MS3110 interfaces to either a differential capacitor pair or a single capacitive sensor. A high-level voltage output signal that is linear with full range of sense capacitance is provided. The MS3110 also includes an on-chip capacitive DAC (up to 10pF) for initial differential adjustments and/or for quasi-differential operation with a dummy capacitor. The MS3110 has provisions for trimming the gain and output offset. Bandwidth is also user programmable. An on-chip EEPROM is provided to store trim and program settings.Features:•Capacitance resolution: 4.0aF/rtHz•Sensor modes: single variable or dual differential variable•On-chip dummy capacitor for quasi-differential operation and initial adjustment•Gain and DC offset trim•Programmable bandwidth adjustment 0.5 to 8kHz (9 steps)• 2.25VDC output for ADC reference/ratiometric operation•Single supply of +5.0VDC•On-chip EEPROM for storage of settings•Available in die or 16-pin SOICApplications:Pressure Sensors Accelerometers (low g)Velocity Sensors DisplacementRate Sensors Fluid ControlTouch Sensors Flow SensorsMotion Sensors Gas SensorsMS3110 Universal Capacitive Readout TM IC Functional Block Diagram:Electrical Characteristics T=25o C Unless Otherwise Spec.Min Typ Max Unit Power Supply Voltage (+V) 4.75 5.00 5.25V Power Supply Current On +V 2.9 6.0mA Power Supply Ripple Requirement On +V100mV Digital DM Inputs- 0.5V+V EEPROM Programming Voltage1618V All Other Inputs- 0.5V+VV2P25 (2.25V Reference) Trimmed 2.237 2.263VV2P25(2.25V Reference) Temperature Stability, Trimmed-5050ppm/o CInput Sense Capacitance(CS1T,CS2T)0.2510pF Resolution/Input-referred Noise 4.0aF/rtHz CS1 Array Coarse Offset Trimmable Range, Nominal09.7pF CS2 Array Coarse Offset Trimmable Range, Nominal0 1.2pF CF Array Coarse Gain Trimmable Range, Nominal019.44pF CF, CS1, and CS2 Trim steps0.0180.0200.022pFBandwidth Selection (9 steps)5008000Hz Bandwidth Tolerance-25+25% Output Voltage Range0.5 4.0V Output Offset @ CS2T-CS1T=0, SOFF=0 2.25VMS3110 Universal Capacitive Readout TM ICElectrical Characteristics Min Typ Max Unit Output Offset @ CS1IN=CS2IN, SOFF=10.5V Output Fine Offset Trim Step6mV/step Output Fine Gain Selectable Range-15+15% Output Fine Gain Trim Step0.12%Output Load Resistance10KΩOutput Load Capacitance100250pF Output Source and Sink Currents247mAOperating Temperature Range (T op)-40+85°C ESD Rating 2.0KV THEORY OF OPERATIONThe MS3110 senses the change in capacitance between two capacitors and provides an output voltage proportional to that change. The capacitors to be sensed are an external balanced pair, CS1IN and CS2IN. The output voltage is a function of the change between the sensing capacitances CS2T and CS1T according to the following:Transfer Function: VO = GAIN * V2P25 * 1.14 * (CS2T-CS1T)/CF + VREFWhere VO is the output VoltageGain = 2 or 4V/V nominalV2P25 = 2.25 VDC nominalCS2T = CS2IN + CS2CS1T = CS1IN + CS1CF is selected to optimize for input sense capacitance range, CF ≥ 1.5pF.VREF can be set to 0.5V or 2.25V DC for ∆CS= CS2T-CS1T =0. For 0.5V DC,the dynamic sensor capacity is constrained by CS2T greater or equal to CS1T. PROGRAMMING SPECIFICATIONSTo allow for such a large range of options, several program modes and trims are incorporated into the MS3110. The user has the option to store the settings into an on-chip EEPROM, which sends the data to the on-chip control registers, or program the control registers directly without memory storage. Both require serial input data, clock, and write signals. Programming the EEPROM requires a +16 VDC supply.TMthe ranges to which the bias and reference frequency should be set is also provided.

The bandgap reference voltage can be trimmed to an optimum voltage with a trim range of +/-5.1%. Since the 2.25VDC reference tracks the bandgap reference voltage, the user can monitor the variation through pin V2P25. The reference level can be trimmed in 20 mV steps. Thus variations of the 2.25V Reference can be trimmed over process. An abridged version of the truth table is included below.V2P25 Reference Voltage Trim (~19mV /step)T3T2T1T0Voltage Trim0000+5.1%1000Nominal1111-5.1%FOR ALL APPLICATIONS, the V2P25 voltage reference should be trimmed to 2.25V +\- 10mV.The current reference can also be monitored and trimmed. The current monitor point is brought out to the TESTSEL pin that normally selects the mode of operation for the MS3110. It also serves to monitor the internal bias current of 10µA, typical when the pin is tied to logic low. The Current reference can be trimmed in 0.8µA steps. An abridged version of the truth table is included below.Current Reference Trim (~0.8µA/step)R2R1R0Current Trim000+32%110Nominal111-32%FOR ALL APPLICATIONS, the current reference should be trimmed to 10µA +\- 2µA.Note that if an external pull-up resistor is placed on the TESTSEL pin of the MS3110 IC, the pull-up current must be factored into the total current, or the external pull-up resistor needs to be removed before the current measurement is performed.Oscillator Control RegistersThe MS3110 has the option to trim the oscillator over process.

Monitoring can be done via CS2IN (PIN-4) or CS1IN (PIN-6).Input Amplifier Control RegistersThe analog front-end includes a capacitance transimpedance amplifier (IAMP) with a programmable feedback capacitor. The capacitor includes 10 bits of programmability in 19fF (+/- 20%) steps. The programmability allows the user to optimize the feedback capacitor for range and performance. An abridged version of the programming truth table is included below.Feedback Capacitor Array CF (9:0) Binary Weighted (in 19fF steps) CF9CF8CF7CF6CF5CF4CF3CF2CF1CF0Capacitor (pF)0000000000000000000010.01900000000100.038:::::::::::10000000009.728:::::::::::111111111119.437The MS3110 is designed to receive a pseudo-differential input sense capacitor arrangement. However, the user may wish to configure the MS3110 to sense a single-ended sense capacitor. For singled-ended operation, the balanced capacitor array CS1 is provided. The CS1 capacitor array gives the user the option to operate in single-ended mode over the entire 0.2pF-10pF range if desired. The capacitor includes 9 bits of programmability in 19fF+/- 20% steps. The resolution of 19fF allows the user to balance the CS1 capacitance with the CS2 external capacitance to minimize offset. An abridged version of the programming truth table is included on the next page and the block diagram shows the location which the feedback capacitor in the signal path.MS3110 Universal Capacitive Readout TM ICBalance Capacitor Array CS1 (8:0) Binary Weighted (in 19fF steps) CS1_8CS1_7CS1_6CS1_5CS1_4CS1_3CS1_2CS1_1CS1_0Cap (pF) 00000000000000000010.0190000000100.038::::::::::100000000 4.864::::::::::1111111119.709When the MS3110 is operated differentially, the external sensing capacitors that are connected to the CS1IN and CS2IN are usually mismatched; this leads to a DC offset in the output signal path. The CS1 Capacitor array along with the CS2 Capacitor array assists in reducing the DC offset by balancing the common-mode capacitance to within 19fF +/- 20% resolution. An abridged version of the programming truth table for the CS2 array is also included below.Trim Capacitor Array CS2 (5:0) Binary Weighted (in 19fF steps)CS2_5CS2_4CS2_3CS2_2CS2_1CS2_0Cap (pF)00000000000010.0190000100.038:::::::1000000.608:::::::111111 1.197Lowpass Filter Control RegistersThe two-pole lowpass filter section is designed with a programmable bandwidth ranging from 500Hz to 8kHz.

They are HV16 (+16VDC), SDATA, SCLK, and WRT. SDATA, SCLK, and WRT are detailed as follows.The 16-bit input data stream per address for writing to the EEPROM Memory Map is defined below. The first bit into the shift register is SP and the last bit is ERN. This represents a portion of the SDATA, or serial data stream.ERN D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 A3 A2 A1 A0 SP (first in)During the Erase mode, ERN is set to logic 0, and the bits following ERN are all don’t care conditions. This will erase the entire memory map. Then ERN is set to logic 1 followed by the D (9:0) and A (3:0) and SP. D (9:0) writes the bits in the location map, A (3:0) represents the address location to write to, and SP is a spare bit. A timing diagram showing the relationship of these waveforms is shown. Note that the first two lines represent an expanded picture of the latter three lines.Note that not all 10 addresses need to be included in the timing diagram. Only the addresses that require a change in the memory need be included.TMControl Register Write Via External Serial DataThe MS3110 is designed with the ability to bypass the EEPROM and load the trim and control data externally into the on-chip Shift Registers. With the TESTSEL pin tied to logic low (active), the user can apply the serial data stream and the clock which the registers strobe to program the trim and controls into the shift registers. There are 58 positions to fill in the data stream. The timing diagram is shown on the next page. The order which the trims and controls are shown below are based on 60 strobe edges. Note that the user can option for 58 strobe edges and ignore the first two don’t care bits, and that the HV16 and WRT pins remain unused in this mode.TMSERIAL DATA WRITE SEQUENCE & MAPPINGDX CNTL NAME DX CNTL NAME DX CNTL NAME DX CNTL NAMED0Don’t Care D15CS1_7D30Don’t Care D45B3D1Don’t Care D16CS1_8D31CSELCT0D46B2D2CS2_5D17CF0D32CSELCT1D47B1D3CS2_4D18CF1D33CSELCT2D48B0D4CS2_3D19CF2D34CSELCT3D49Don’t CareD5CS2_2D20CF3D35SOFF D50D2D6CS2_1D21CF4D36OFF4D51D1D7CS2_0D22CF5D37OFF3D52D0D8CS1_0D23CF6D38OFF2D53T0D9CS1_1D24CF7D39OFF1D54T1D10CS1_2D25CF8D40OFF0D55T2D11CS1_3D26CF9D41B7D56T3D12CS1_4D27Don’t Care D42B6D57R0D13CS1_5D28GAINSEL D43B5D58R1D14CS1_6D29Don’t Care D44B4D59R2Volatile Register Read Out / EEPROM VerificationThe shift register can be read out to verify the proper settings for the trim and controls; EEPROM data retention can also be verified in the following way.

Featuring quickdisconnect fittings for sample connections and a rugged lightweight housing with handle, this versatile instrument can be brought to the sample site and set up for analysis quickly and easily. Because of the intrinsically safe design, once calibrated, the instrument can beemployed even in hazardous environments without compromise. The Model 3110 incorporates a large standard feature list designed for versatile, accurate oxygen analysis for a wide range of applications. Figure 1-1 shows the standard Model 3110 Portable Trace Oxygen Analyzer.The microprocessor based Model 3110 instrument provides user settable analysis ranges at the trace level. The range can be set from 0-2 ppm to 0-25% oxygen. In auto-ranging mode two ranges can be set and the analyzer move between these ranges as required. The adjustment resolution is 0.1 ppm for trace analysis.Sample oxygen is displayed on a 2-line 20 character alphanumeric LCD display mounted on the front panel. Four buttons are used to interface with the instrument and access all of the analyzer features.Sample gas is introduced and vented via a pair of quick-disconnect fittings that feature integral shutoff valves that automatically close when the mating male fitting is withdrawn. The fittings are an integral part of the measuring cell manifold.Portable Trace Oxygen AnalyzerIntroductionWARNINGThough the 3110 can be applied to monitor percentoxygen, doing so will lead to more frequent sensorreplacement requirements.Figure 1-1: Model 3110 Portable Trace Oxygen Analyzer1.2 FeaturesThis instrument is designed to be a versatile analytical instrument and to perform reliably and accurately in analyzing oxygenconcentrations in gas mixtures from the ppm level through 25% oxygen. The following features are standard on the Model 3110:• Data Logger: The optional built-in data logging feature allows the user to specify the time intervalbetween data recording sets. The date,time, and oxygen concentration readingsare stored in internal RAM at the userspecified interval. The data set can beIntroduction Model 3110downloaded using the instrument’soptional RS-232 interface.•Display: A 2-line 20 character alphanumeric LCDon the front panel displays data andoperational information through variousscreens. The contrast is adjustable forvarious lighting conditions.•Four-Button User Interface: Operation is performed using thefour front panel mounted buttons. Thesebuttons are used to enter data, select itemsand move through operational screens thatappear on the display.•Universal AC Charge Adapter: The rechargeable batteries canbe recharged without removing them fromthe instrument. The charger operates overthe range of 100-240 VAC.•LEDs:Two front panel mounted LEDs are usedto indicate low battery condition and whenthe battery is recharging.•Contrast Control:This feature allows the user to easilyadjust the contrast of the display foroptimum viewing under different lightingconditions. The adjustment is made usinga front panel control dial.•Auto-ranging:The user is able to specify two analyticalranges for analysis in the auto mode. TheModel 3110 will automatically switchbetween these ranges depending on theoxygen level.•Percent of Range Voltage Output: An optional 0-1 VDCoutput is available that represents thepercentage of the current analysis range.•Real-time Clock:This feature allows the Model 3110 to dateand time stamp the data set recorded onthe data logger. It uses a 24 hour clock.Portable Trace Oxygen Analyzer Introduction•Quick Disconnect Fittings:Dual self-sealing quick disconnectfittings are installed for making easysample connections.1.3 Method of AnalysisThe sample oxygen is measured by a unique electrochemical transducer which functions as a fuel cell; in this instance, the fuel is oxygen. Oxygen diffusing into the cell reacts chemically to produce an electrical current that is proportional to the oxygen concentration in the gas phase immediately adjacent to the transducer’s sensing surface. The linear, but minute signal produced by the transducer from oxygen is amplified by a two-stage amplifier. The O2 sensor output signal is digitized and fed to the microprocessor. Additional signal conditioning and temperature compensation are handled electronically and appropriate signals are directed to the display and output ports.1.4 Micro-Fuel CellThe micro-fuel cell (U.S. Pat. Nos. 3,767,552 and 3,668,101) is a sealed electrochemical transducer with no electrolyte to change or electrodes to clean. When the cell reaches the end of its useful life, it is removed, properly disposed of, and replaced with a new cell. The life of the cell is warranted by TAI (see below).The cell is specific for oxygen and is not sensitive to flow rate or reducing agents such as hydrocarbons, carbon monoxide, sulfur dioxide, etc. In the absence of oxygen, no current is produced; thus, no zeroing is required.1.4.1 Cell WarrantyThe Class B2-C, A2C, B2C-XL and Insta Trace micro-fuel cells can be used in the Model 3110 and are warranted for six (6) months from the date of shipment.With regard to spare cells, service time starts when the cell is removed from its shipping package. You should stock only one spare cell per instrument at a time.If a cell was working satisfactorily but ceases to function before the warranty period expires, the sensor will be replaced at no cost.Introduction Model 3110 If you have a warranty claim, return the cell in question to thefactory for evaluation. If it is determined that failure is due to faultyworkmanship or material, the cell will be replaced at no cost to you. WARNING: EVIDENCE OF DAMAGE DUE TO TAMPERING ORMISHANDLING WILL RENDER THE CELLWARRANTY NULL AND VOID.The Model 3110 is designed to meet Factory Mutual standards for intrinsically safe for Class I, Division I, Groups A, B, C and D hazardous locations. (Approval pending at time of manual printing.) This safety feature does not apply when the instrument is being charged with the 100- 240 VAC external charge adapter. The instrument should be removed from hazardous areas when the batteries are being charged.Note: Do not use the analyzer when the battery charge is low. 1.5 Accuracy and ResponseThe Model 3110 provides monitoring accuracies of ±2% of full scale or ±1 ppm, whichever is greater, at constant temperature.With a sample flow rate of 1 SCFH, a 90% response can be realized in 60 seconds. The response time on the 3110 is limited by the filter setting.1.6 Signal OutputThe standard 0-1 VDC output has a 100 ohm impedance and is suitable for driving external devices that have an input impedance of 10,000 Ω or more. The signal output is available from a port on the rear panel.1.7 Compact PackagingThe instrument is housed in 6 1/8" × 9 ½" × 5 5/8" (156 × 241 ×143 mm) aluminum case that is equipped with a carrying handle and foot pads. Unlike analog instruments where uneven positioning mayPortable Trace Oxygen Analyzer Introduction affect meter accuracy, the Model 3110 can be used in any position without interference.Introduction Model 3110Intentionally left blank.Portable Trace Oxygen AnalyzerInstallationInstallationThe Model 3110 Trace Oxygen Analyzer is designed to be portableand easy to setup and configure. To setup the analyzer:• Read the Manual• Charge the battery• Install the sample and vent gas lines• Install the trace sensor and purge the analyzer• Calibrate the analyzer• Set the sample gas flow rate2.1 Charging the BatteriesThe unit is powered by 2 Intrinsically Safe rated sub-C Ni-Cd batteries and is shipped with batteries fully charged. The batteries, however, will require periodic recharging. For recharging, access to an AC power source of 100 to 240 volt, 50/60 Hz will be required and the instrument should not be recharged in a hazardous area. Connect the universal AC charger adapter supplied with the instrument to the AC power outlet. Plug the other end of the charger into the port on the rear panel as shown in Figure 2-1. The green charge indicator LED should be illuminated to indicate that the unit is charging.To fully recharge a set of batteries will take approximately 16 hours. The instrument should not be left on the charger for longer than 20 hours nor should the charger be left attached to the instrument when the unit is not charging. The Model 3110 cannot be operated while the battery charger is attached.CAUTION:DO NOT CHARGE THE BATTERY IN A HAZARDOUS AREA. THE INTRINSICALLY SAFE CLASSIFICATION OF THIS INSTRUMENT DOES NOT APPLY WHENTHE CHARGER IS ATTACHED TO THEINSTRUMENT. REMOVE THE INSTRUMENT TO ANON-HAZARDOUS AREA BEFORE CONNECTINGTHE BATTERY CHARGER TO THE INSTRUMENT.Installation Model 3110 The unit can operate continuously for approximately 4 days on a setof fully charged batteries. If more frequent charging is required, the batteries are approaching the end of their useful life and should bereplaced. See Battery Replacement in Section 4.3 of this manual.A low battery condition is indicated by a blinking red Low Battery LED on the front panel. This will also cause the display to flicker along with the blinking LED due to the power drain and low battery condition. At this point the unit should be removed from service and the batteries recharged.Figure 2-1: Model 3110 Rear Panel2.2 Gas ConnectionsThe customer must provide a means of controlling the pressure and flow rate of the sample and zero gas. For positive pressure applications, TAI suggests a simple throttle valve installed in the sample line between the sample point and the analyzer. The flow rate should be limited to between 0.2 and 2.5 SCFH. The sample in port is used for both samplePortable Trace Oxygen AnalyzerInstallationand calibration gas. For atmospheric pressure sampling, connect a pump and flow control valve downstream from the analyzer and draw (rather than push) the sample through the instrument.IMPORTANT: IF A PRESSURE REGULATOR IS USED, IT MUSTHAVE A METALLIC DIAPHRAGM. REGULATORSWITH ORGANIC OR PLASTIC DIAPHRAGMS AREPERMEABLE TO OXYGEN AND, IF USED IN THE SAMPLING SYSTEM, WILL LEAD TO HIGH OXYGENREADINGS.The instrument is shipped with a gas sampling and calibration kit. This includes a 12” piece of clear tubing with a quick disconnect line for use as a sample return or vent line plus 2 quick disconnect fittings to be installed on the sample and calibration lines. These fittings employ ¼” tube fittings which can be removed to reveal a 1/8” NPT internal thread.It is important in trace analysis applications to use metal for allwetted components of the sample system. This includes gas lines, filters, pump housing, diaphragms and any components in contact with the sample gas. Plastic tubing and parts will result in slow and inaccurate measurements at the ppm level.There are two quick disconnect fittings installed on the rear panel for mating the instrument with the sample or calibration gas and the vent line. As shown in Figure 2-1, each fitting has a button which when depressed allows the rapid detachment of the gas line from theinstrument. It is not necessary to press the button when inserting the line, just push the male fitting into the mating connector. When a line is removed, an internal seal prevents gas escape from the female sections of the fitting.To avoid pressurizing the sensor, the vent line should beinstalled first and removed last.In setting up the sample lines, any valves used to set the sample flow or filters must be located on the sample in line. Do not place any valves or restrictions on the vent line except as noted above foratmospheric pressure sampling when using a downstream pump. Doing so would increase the sensor operating pressure and result in inaccurate analysis.Installation Model 3110 For trace analysis applications, a flowmeter should be installed in the vent line but it should not incorporate any control valves or restrictive devices.2.3 Sensor InstallationThe Model 3110's trace sensor requires that the instrument lines be immediately purged with zero gas after installing the cell.2.3.1 Installing a Trace SensorPrior to installing the trace sensor, make sure the analyzer is ready to purge with zero gas. Connect the vent line to the analyzer then connect the zero gas line to the sample in port. Set the zero gas flow rate between 0.2 and 2.5 SCFH.Prior to using any bottled gas for calibration or purge, it is good practice to bleed the regulator and sample line to remove any traces of trapped air. See Section 2.4.3 Bleeding the Regulator and Purging the Gas Line.Once the vent and zero gas lines are attached and the lines bleed, proceed to install the trace sensor as follows:1.Remove the cell holder cap from the bottom of theinstrument.2.Remove the outer packaging from the sensor.3.Grab the shorting plug on the top of the sensor and pull itfree prior to removing the sensor from its packaging.4.Remove the packaging and rapidly place the sensor on thetop of the cell holder cap with the concentric gold ringsfacing up.5.Screw the cell holder cap and sensor into the bottom of theanalyzer.Note: Minimize the time the sensor is exposed to air.6.Start the purge flow through the analyzer and purgeovernight before calibrating the unit.Portable Trace Oxygen Analyzer Installation2.4 CalibrationCalibration involves using a span gas to set the span of the instrument. The proper span gas concentration depends on the range that the instrument will be used on. The correct concentration should be 80-90% of the range used. For instance, if the analyzer is to be used on a range of 0-150 ppm oxygen, then a span gas should be prepared with 120-135 ppm oxygen in nitrogen.2.4.1 Calibration Procedure for Trace AnalysisTo calibrate the Model 3110, the instrument must be fitted with a trace sensor. The instrument must also be purged overnight using a zero gas (a pure gas with no oxygen, typically O2 free N2) before calibrating. For A-2C type cells, match the CO2 content in the span gas to that of the sample gas.To calibrate the analyzer for trace analysis:1.Purge the analyzer overnight.2.Purge the calibration gas sample line, regulator, and controlvalve. See Section 2.4.3.3.Set the calibration gas flow rate to 1 SCFH.4.Attach the vent line followed by the span gas line using thequick disconnect fittings.5.Navigate to the SPAN VALUE screen (see Section 3.2.13)and set the span value to the known oxygen concentration inppm of the span gas.6.Observe the oxygen reading on the screen to determine whenthe reading has stabilized.7.Navigate to the SPAN screen and select SPAN: START.8.When the screen changes and displays SPAN: FINISH, selectSPAN: FINISH to set the span.9.Allow the span gas to flow for several minutes to verify theproper span setting.10.Calibration is complete. Remove the span gas line firstfollowed by the vent line.Installation Model 31102.4.2 Bleeding the Regulator and Purging the Gas LineWhen using bottled gas (gas cylinder) as a calibration gas for trace analysis applications, the regulator and sample lines must be bled to remove traces of trapped air. Otherwise air that is trapped in the lines especially between the regulator and cylinder will result in a lengthening of the calibration time.To bleed the regulator and sample line:1.Attach the regulator to the gas cylinder. Then attach a sampleline with a flow control/shut off valve preferably at the farend of the sample line.2.Open the shut off valve slightly, and then open the valve onthe gas cylinder.3.Adjust the regulator to the desired pressure (usually 5 psi)then close the cylinder valve.4.Open the cylinder valve to pressurize the regulator fully thenclose the cylinder valve again.5.Open the sample flow control valve and allow the gas tobleed down and vent to a safe area. Observe the secondarygauge (low pressure side) on the regulator. As the lowpressure gauge starts to fall, close the sample flow controlvalve.6.Repeat steps 4 and 5 seven (7) times.The sample delivery system is now purged and ready for calibration or analysis. Keep the cylinder valve open to maintain system pressurization.Note: Make sure there are no leaks in the sample line and regulator connections. Check also the cylinder connectionfor leaks.2.5 Set the Sample Flow rateOnce the system has been calibrated, the instrument can be brought to the analysis site and the sample gas line can be connected to the unit. Using the quick disconnect fittings supplied; connect the vent line followed by the sample line to the rear panel. See Figure 2-1.Once the sample gas is flowing, set the flow rate to 0.2-2.5 SCFH.Portable Trace Oxygen Analyzer Installation2.6 External SignalThe standard 0-1 VDC output signal represents the percentage of the current range. For instance, if the range was set for 0 to 10 ppm, then 0.1 V would represent 1 ppm, 0.2V would be 2 ppm; 0.3V would be 3 ppm etc.This output signal, when installed, is accessible from the rear panel. The output signal has an input impedance of 100Ω.。
