Hand-held static sensor locates and meas-ures static voltages, tests air ionizers.New from 3M,the 718 Static Sensor can help companies competing in the global high-tech marketplace prevent cost-ly losses due to electro static discharge (ESD) damage by playing a vital and valuable role in their own ESD control program. Easy to use,the hand-held 3M ™718 Static Sensor is designed to measure static voltages on objects and sur-faces arising from electrostatic charge buildups,and can help identify ESD trouble-spots — ensuring product relia-bility and customer satisfaction which translates into com-pany profits. As a bonus,when used in conjunction with the 3M TM Model 718A Air Ionizer Test Kit,the 718 can also be used to verify the operation of air ionizers.718 Static Sensor Features• Small-size,lightweight,conductive plastic housing • Membrane switches for Power,Range/Zero,and Hold functions.• Digital,LCD (liquid-crystal) display is easy to read and updates quickly.• Ranging system assists user in making quick and easy measurements• Measurements accurate to 5%• Output jack available for continuous measurements Convenient Size/Low Power Requirements The 718 is small enough to be carried in a pocket andweighs less than 5 oz. (142 g),including battery. The light-weight plastic housing is conductive,allowing a properly-grounded user to dissipate all electrostatic charges from the surface of the meter.Meter FunctionsThe meter is equipped with three membrane switches which control different functions. The POWER switch turns the instrument on and off. The RANGE/ZERO button performstwo functions; when pressed momentarily it switchesbetween the two measurement ranges of 0-2,000 volts and 0-20,000 volts,and if held for longer than 3 seconds,it resets the voltage display to 0 volts. The HOLD button allows the user to freeze a measurement on the LCD for later review.Ranging SystemIncluded with the 3M 718 Static Sensor is a ranging system consisting of two light-emitting diodes (LEDs) which each emit a circular red light onto the surface being measured for static. When the two lights intersect and form a single focused light,the measurement distance is the prescribed 1 inch (2.54 cm).AccuracyThe Model 718 Static Sensor is accurate to within ±5% of the displayed measurement,at a distance of one inch (2.54 cm) from the target. Accuracy will vary as the dis-tance between measured object and instrument changes from the one inch (2.54 cm) specification.Analog Output JackThe analog output jack located in the front of the unit pro-vides a convenient hook-up,via a 3/32 inch (2.5 mm)monophone jack,to a recorder/data acquisition console. The 3M 718 Static Sensor may then be used for remote monitoring or permanent recording of electrostatic voltage readings.3M 718 Static Sensor SpecificationsDimensions 0.85" (H) x 2.4" (W) x 4.15" (L)2.2 cm (H) x 6.1 cm (W) x 10.5 cm (L)Weight4.5 oz.

3M ™ ESD Pro Event DetectorLocate and identify ESD events in your processThe ultimate goal of an ESD program is to reduce the strength and occurrences of ESD events, or electrostatic discharges. ESD events can destroy sensitive components during their manufacturing, handling and assembly. Knowledge of the presence of ESD events and their relative strength is critical for assessment of the ESD environment and for determining whether the production environment is suitable for handling ESD-sensitive devices. The only way to verify that your ESD protection works is by knowing whether you have ESD events in the environment, how strong they are and how many of them occur. The portable, easy-to-use 3M ESD Pro Event Detector serves as a quick measure of the effectiveness of your ESD protection.The ESD Pro is a hand-held indicator of ESD events that detects and counts the discharges as well as shows the relative strength of each ESD event. The ESD Pro offers variable settings of the discharge alarm threshold to detect and count only those discharges that exceed the threshold. The ESD Pro provides an audio alarm on each discharge and an LED bar-graph to show the relative strength of the ESD events. If the discharge exceeds the set alarm level, the LEDs turn red.The ESD Pro is capable of rejecting most non-ESD related EMI (electromagnetic interference) events. This special proprietary charge device model (CDM) mode allows assessment of the ESD environment in places where EMI events resulting from stepper motors, solenoids, relays and sources abound.Applications for the ESD Pro include electronics assembly, semiconductor device manufacturing, disk drive manufacturing, medical environments and military aerospace.33M™ ESD Pro Event Detector, CTM082Features BenefitsESD Event Detection ESD Pro provides detection of electrostatic discharges (ESD events) that are harmful for sensitive components.Adjustable Alarm Threshold Easy-to-set alarm threshold helps to set a level below which ESD Pro rejects events as insignificant for a particular application.ESD Event CountESD Pro has a four-digit counter to provide a count of discharges above the set threshold.Rejection of Non-ESD EventsProprietary waveform analysis algorithm in its CDM mode rejects most non-ESD EMI events to provide accurate detection of legitimate discharges in noisy environments.PortabilityA small hand-held instrument that can be carried and used anywhere for quick assessment of ESD environments. ESD Pro belongs in the toolbox of every engineer and technician who is concerned with ESD damage to their parts.ESD or EMI?Often, devices such as relays, solenoids, stepper motors, and others generate signals similar to those of ESD events. In order to separate genuine ESD events from those caused by equipment operation, ESD Pro uses patent-pending signal processing to differentiate signal waveforms with the focus on CDM-type events that are most critical in electronics manufacturing.EMI EventESD EventImportant NoticeAll statements, technical information, and recommendations related to 3M’s products are based on information believed to be reliable, but the accuracy or completeness is not guaranteed.

3740 Wrist strap +shoe testerOperating Instructions MO 0688-0201February, 2001II. Declaration of ConformityThe 740 Wrist Strap and Shoe Tester is in conformity with the regulations of the EMC-directive 89/336/EWG. The following standards have been taken into account while designing and manufacturing the instrument: EN 60204-1/85,EN 60204-1/91, EN 61010 (Safety),EN 50082-1/92 and EN 50082-2/92.I. GeneralPersonnel grounding devices such as wrist straps and conductive footwear are the primary method to minimise charge generation on the human body. They must be able to drain this charge as rapidly as it is generated.For this reason, it is important to test wrist straps and conductive footwear on a regular basis to ensure they are functioning properly and that the test results can be recordedGround cord 4 mm studContact plate for wrist strap teste.g. - data transfer to PC, electrical door opening system, acoustic signal, etc.selection for wrist strap and shoe testshoe electrode On / Off switchRmax III. DescriptionThe 740 wrist strap and shoe tester is an electronic test instrument which is easy to operate and designed to be wall mounted. An AC/DC -transformer is supplied. The 740 switches off automatically after non-use for approximately 30minutes.The unit consists of two measurement circuits with an open circuit test voltage of 20 V for wrist strap and shoe test applications. For wrist strap and footwear testing, a minimum thresholdresistance of 750 k Ω is set internally. The desired maximum allowable resistance level can be selected separately for each measurement. If the resistance of the tested wrist strap or footwear is within the selected range, the green "o.k."-LED will illuminate. The red "<" -LED alerts theoperator that the resistance of the tested device isunder 750 k Ω. The red ">"-LED indicates that theselected maximum resistance is exceeded.The 740 can be connected to external devices such as computers (for data recording), electrical door opening systems, counter or other evaluating components.The 740 wrist strap and shoe testerconsists of:-3.5" - diskette containing instruction manual and 740 daily log sheet - Base unit-Data output connector plug-Wall mounting kit, 3M Dual Lock ™ fastening system and template-Cover for wrist strap plug-in jack -AC/DC - transformer -Ground cordAccessories:-Shoe electrodes type 741 (single electrode) or 741D (dual electrode) (to be ordered separately).IV. OperationConnect the AC/DC - transformer (DC 24-30 V,150 mA) to the 740 tester.Note: If you notice a delay in the response time of the LED illumination please connect the ground cord supplied to the ground socket of the 740.Please ensure proper earth ground connection!Switch the unit on. All LEDs will flash forapproximately 1 s to check their function. Selectthe desired upper maximum resistance level forboth the wrist strap and shoe test by using a smallscrew driver.The 741/741D shoe electrode must be connected if footwear testing is required.V. Wall MountingThe enclosed 3M Dual Lock™ fastening discsmust be screwed to the wall using the attachedtemplate approximately 1500 mm (5 feet) abovethe floor. Drill three holes of 5mm (0.2 in)diameter at marked locations. Make sure the areaon the 740 in which the Dual Lock™ fasteningstrips are placed is free of dust and dirt. Attach the3M Dual Lock™ fastening strips to the rear of the740 tester to the bottom and top in parallel; seedrawing for locations.For securing on the wall, press the 740 firmlyagainst the discs. For removal of the 740, lift thetop corners with both hands.VI. Wrist Strap TestPut the wrist band on with ground cord attachedand insert the ground cord into the wrist strapplug-in jack. Depress the metal contact plate andhold it. One of the indicator-LEDs will illuminate.An illuminated green LED indicates that the wriststrap performs within the resistance range of750kΩ to the upper selected value of 2, 5, 10 or35 MΩ. If a red "<"-LED is on, the currentlimiting resistor in the ground cord is bypassedand the cord has to be replaced. The red ">"-LEDindicates that the selected resistance range isexceeded. Check to see if the high resistance is inthe cord, the wrist band or in the contact betweenwrist band and the operator’s skin. To check theresistance of the ground cord, leave the plug endof the ground cord attached to the tester anddisconnect the snap end from the wrist band.Connect ground cord snap to the stud in the handsymbol or press it onto the contact plate anddepress the plate until one of the LEDs isilluminated.TemplateIf the green LED illuminatesnow, the ground cord can beused.If the red ">"-LED is lit,replace the ground cord.In some cases, high contact resistance between theskin and wrist band will cause the tester to show ared ">" - LED condition. This resistance may becaused by dry skin or the presence of hair in thewrist area. The use of a skin lotion isrecommended to solve this problem.If a red ">"- LED condition still exists, replace thewrist band.VII. Shoe testEither the 741/741D shoe electrode must be connected to the 740 shoe jack.a) when the 741 single shoe electrode is used:If the red ">"-LED is illuminated, clean the soles of the shoes or check shoe grounding system (heel ground or toe ground strap) and retest. If, after cleaning, the red ">"-LED remains lit, replace it by an appropriate device. If the red "<"-LED is illuminated, the minimum resistance of the shoes or shoe grounding system is under 750 k Ω.An electrical hazard to personnel may exist at the work place.b) when the 741D dual shoe electrode is used:The dual shoe electrode allows differentiation between the right and left shoe; giving the right shoe a preference in indication. This means, if both shoes or just the right one are out of range,you will get identical indications as it would be with the single shoe electrode. If just the left shoe is out of range, the corresponding red LED will flash. Consequently, in case of a steadily lit red LED, you shall clean or remove right shoe first and retest. If the right shoe is in the "ok"-range then, you will obtain information aboutperformance of the left shoe and you can react accordingly.The shoe test does not influence the wrist strap test, therefore the shoes can be tested while the wrist strap is still connected to the 740 or the wrist strap can be tested while the operator is standing on the 741 shoe electrode. Both metal plates shall not be pressed at the same time.Switch the 740 on. Stand on the applied shoe electrode. If you are using shoe straps with a 1M Ω - resistor on both feet to be tested with the 741 shoe electrode, you have to test the straps one after the other, to avoid a red "too low" -indication. Care must be taken not to put the non-tested foot on ESD - protective flooring to avoid a bypass to ground. Depress the metal contact plate for shoe test until one of the indicator - LEDs lights up. The green LED indicates that theresistance of the person through the footwear is in the range between 750 k Ω and the desired upper maximum level (10, 35, 50 or 100 M Ω).VIII. Data Output ConnectorIf you are going to use the data output connector you must follow a test sequence. It must be wrist strap test first and then the shoe test. If this sequence is not strictly kept, the output at the pins described on page 7 will be mixed up .The 740 will provide digital signals (high/low) while testing the personnel grounding devices. These digital signals can be used for data recording (Example 1) and authorisation control equipment such as electrical door opening systems (Example 2). The output of the 740 will give you permanently +5 V at pin 3 and DC-return at pin 6. The remaining pins 1, 2, 4 and 5 (open collector) will be high(max.+30 V/20 mA have to be provided externally) or low (DC-return) while pressing on the contact plates either for wrist strap or shoe tests. The chart on page 7 shows all of the possible test results and the corresponding output levels.Example 1: Output connection for use with a computer Example 2: Output connection for use with a controlling deviceComputer input Computer groundData output connector pin status when testing wrist strap/shoeThe sequence for testing must be wrist strap test first and then the shoe test.Shaded pin indicators will read "hi" if the sequence is reversed or only the shoe tests are performed.Data Output Connectorpin 1, 2, 4, 5-high or low pin 3-+5 V pin 6-DC-returnIX.

Calibration ProcedureThe following procedure can be used to determine if the 740 operates within its specifications.Please note: The tester has no adjustable components.Equipment needed:1.Resistors750 k Ω - 120 M Ω, tolerance ± 1%2. 2 leadsas required to connect the reference resistora) calibration of wrist strap test circuit:Connect the reference resistor to the 740 as shown in the figure below. Switch the 740 unit on. Select the 2 M Ω-range and use the reference resistors as indicated in the test table and press contact plate A.b) calibration of shoe test circuits:The 740 Tester can either operate with the single or dual shoe electrode. They are identified by the wiring in the 3-pin plug according to DIN 41 524,type HIRSCHMANN MAS 3100, that connects the shoe electrode to the 740. For the single shoe electrode, the cord is connected to pin 1 while pins 2 and 3 are shunted and grounded.The dual shoe electrode uses the same plug but has got the following connections:pin 1: right shoe electrode pin 2: openpin 3: left shoe electrode.Reference Resistance LED -resistor range settings Indication *750 k Ω 2 M Ω - rangeRed 900 k ΩGreen 1.8 M ΩGreen >2.2 M ΩRed 4.5 M Ω 5 M Ω - range Green >5.5 M ΩRed 9.0 M Ω10 M Ω - range Green >11.0 M ΩRed 31.5 M Ω35 M Ω - rangeGreen >38.5 M ΩRed*This example is used aboveThe LEDs will indicate as shown below if the 740performs within specifications. Repeat this procedure for 5, 10 and 35 M Ω-ranges.11.1 MΩII) calibration of the dual shoe test circuits: The 740 Tester measures the resistance of both shoes almost at the same time. The test result for the circuit of the right shoe has got priority. The calibration can be either performed with two reference resistors for both circuits to be checked at the same time or -corresponding to the single shoe test - with one reference resistor for one circuit to be checked and an appropriate bridge resistor (1MΩ e.g.) for the other circuit. For completion of calibration, the test has to be repeated with connections of the resistors vice versa. Follow the instructions for the single electrode calibration test accordingly.For the operation with two reference resistors proceed as follows: Connect one reference resistor between contact 1 of the socket and the stud and the other one between contacts 2 and 3. Select the 10 MΩ-range and set the reference resistors as indicated in the test table and press contactplate B. The LEDs shall light as shown below.
