DO30A多功能校准仪

Specification Sheet SS-CP-2385-USPRODUCT DESCRIPTIONThe AMC910 multi-purpose calibrator is the right solution for high precision signal, temperature, and pressure calibrations, as it combines the power and features of a laboratory calibrator, with the addition of an isolated measurement channel.The AMC910 calibrator offers laboratory grade accuracy, high per-formance and simple-to-use functionalities. With the optional exter-nal pressure modules, the system may be taylored to address all possible calibration needs.FeaturesThe JOFRA AMC910 not only offers temperature and pressure calibration features, it combines sourcing of current and voltage, measurement of millivolts and resistance with a second completely isolated measurement channel for a single laboratory calibration instrument unmatched in ver-satility, performance, and value. This flexibility means that only one unit is needed for calibration or verification giving the confidence needed for test instruments as well as for field calibrations.The JOFRA AMC910 has the ability to store up to 9 setpoints for each output range. The setpoints can be selected manually or automatically stepped at timed intervals. The AMC910 also features an intuitive, easy-to-operate user interface and computer control through the RS232 or IEEE-488 interface for automated production testing. The unit sources DC voltage and current for multifunction workload coverage, enabling calibration of data loggers, strip chart recorders, multi-meters, handheld calibrators, and other industrial instruments. This is the cost-effective solution for multiple calibration needs.Model AMC910Advanced Multi-purpose CalibratorN ow wi t h s ou r c i n ga n d me a s u r i n g i no n e i ns t r u m e n t2Direct keyboard entry (1)The JOFRA AMC910 provides simple, front-panel entry of mode,range, and value. Using direct keyboard entry (1), the exact valuedesired is entered using the numeric keys, and the ENTER keyis pressed to set the output to that value. Whichever way youchoose, setup is simple and fast. In the voltage output mode, theJOFRA AMC910 auto-ranges on the entered value for maximumaccuracy at all times.Curser entry (2)Using cursor entry (2), the LEFT/RIGHT arrow keys are used tomove the cursor under the digit in the display to be changed. TheUP/DOWN arrow keys increment/decrement the value at the cur-sor position.Choose the mode you want (3)Voltage ModeThe JOFRA AMC910 offers four precision voltage output ranges(100mV, 1V, 10V, and 100V) all with ±0.003% of reading ±0.001%F. S. accuracy. These ranges are ideal for calibrating a broadrange of DC voltage instrumentation. Additionally all voltageoutputs settle to full specification in less than 200ms making theJOFRA AMC910 ideal for automated calibration systems.An automatic stand-by mode (3) assures that output voltagesabove 30VDC must be acknowledged by the operator before thevoltage appears at the output jacks. The stand-by mode is alsotriggered if the output current compliance is exceeded, therebyprotecting the device under calibration.Current ModeThe JOFRA AMC910 features a precision current output range(100mA) that offers 0.01% accuracy, which is ideal for calibratingprocess instrumentation especially 4 to 20mA equipment. Witha full 12 volts of compliance at 100mA virtually any precision DCcurrent measuring device can be calibrated using the JOFRAAMC910. Like the voltage ranges the current range offers quicksettling time and an operate/stand-by mode.Thermocouple ModeThe JOFRA AMC910 can read and source any of 11 typesof thermocouples. Its T/C input and output is Cold JunctionCompensated, using an ultra-stable PT-1000 sensor.RTD ModeThe JOFRA AMC910 can read and source 9 RTD types as well asYSI-400 and Ohms for non-standard curves. Probe coefficients (A,B, C, and R0) can be entered directly, with storage for up to fivecustom curves and one SPRT curve. The performance of the JOFRAAMC910 in the RTD mode compares to dedicated RTD measure-ment instruments. Unlike low-cost, less accurate RTD instruments,the display in the JOFRA AMC910 is always active, reading to threedecimal places, using polynomial averaging to extract a high accu-racy signal. The result is a very high accuracy reading.Pressure ModeSignal calibration capabilities of the JOFRA AMC910 include, cur-rent, voltage and resistance. In temperature mode, the unit can readand source any of 11 types of thermocouples and 9 RTD types aswell as YSI-400 and Ohms for non-standard curves. In pressuremode, the instrument operates with all JOFRA APM modules andcovers pressure ranges from vacuum to 700 bar / 10,000 psi, select-able through more than 60 different pressure modules, representingvacuum, absolute, gauge and compound pressure types as well asSetpoint Control (4 and SPT)A SHIFT key (4) provides easy accessto the setpoint controls of the JOFRAAMC910. Up to nine setpoints canbe defined for each output mode andeach thermocouple and RTD type.Setpoints are recalled individually atthe touch of three buttons, SHIFT (4),SETPOINT (SPT) button and then thecorresponding numeric keys 1-9. Anynumber of sequential setpoints canbe stepped through automatically,with complete control of dwell time.Either way, for rapid setup of repeat-able tests, no other instrument comesclose to the JOFRA AMC910.Remote Control (4)All of the JOFRA AMC910 operating functions can be accessedvia RS232, IEEE-488 or optional USB interface cable using astandard PC running Windows® HyperTerminal or other soft-ware using an ASCII protocol. Custom control programs maybe written using programming software such as C++. Switchingbetween LOCAL and REMOTE is as simple as touching theSHIFT (4) and LOCAL buttons.Rock-Solid StabilityThe accuracy of the JOFRA AMC910 is specified for both 90-dayand one-year intervals. Manual zero calibrations can be made onall T/C and pressure functions to eliminate offsets.Flexible Output (5, 6 and 7)Five-way copper alloy binding posts (5) provide a wide range ofconnection options. A standard pressure module connector isprovided (6), as is the CJC T/C mini-jack (7).Isolated Measurement Channel (8 and 9)The JOFRA AMC910 features a fully isolated measurement chan-nel which allows the user to calibrate process transmitters andsignal isolators. In reality it’s like having two instruments in one!This channel also incorporates a 24 volt loop power supply topower 2-wire transmitters and a HART interface resistor enablingdirect connection to HART communicators. Key features are:Two voltage ranges 10V and 100V DCMilliamp range 0 to 50mAMilliamp range with simultaneous 24 volt power (0 to 24ma)Selectable 250 ohm HART resistorAccuracy of 0.005% of reading on all ranges•••••3SPECIFICATIONS AMC910(1 year at 23°C ±5°C;
