Figure 1. (Left to right) SCS 718 Static Sensor and SCS 718A Air Ionizer Test Kit.718 is a portable handheld instrument used for locating and measuring electrostatic charges. It can be used to locate ESD trouble-areas, and is a valuable tool for the ESD-control engineer. Used in conjunction with the SCS Air Ionizer Test Kit 718A (sold separately), it can be used for verification and auditing of air ionizers. The Static Sensor 718 is battery-powered and has several measurement features:measurements can be taken in a 0 to ±1.999 kVThe SCS Static Sensor 718 has a Low Batteryindicator. Once the battery is depleted toapproximately 6.5 volts, the instrument will showBAT in the display. At this time, the Static Sensor718 will not produce accurate results and the batteryOperation of the Static Sensor 718For accurate measurements during usage, it is recommended that the outside housing of the Static Sensor 718 be connected to an electrical ground.This can be accomplished by having the user holding Figure 2. SCS 718 and 718A Battery Replacementand Indicators.Made in theUnited States of AmericaTo shut off the Static Sensor 718, momentarily press down on the membrane switch labeled POWER. Determining that the power is off can be verified by seeing that the liquid-crystal display (LCD) is off. Making Electrostatic Voltage Measurements: hold the instrument 1-inch (2.54 cm) away from the object being measured. The display will update with the voltage measurement in kilovolts. If the measured voltage is greater than the measurement range of the instrument, a -1. Will be displayed. At this time, switch to a greater range. If over-ranging occurs even with the high range activated, the static charge on the object cannot be measured with the Static Sensor 718.Measurement Range: all measurements are in kilovolts (kV) as stated on the front label of the unit. The StaticSensor 718 has two measurement ranges: 0 to ±1.999kV and 0 to ±19.99 kV. The unit’s current measurementrange mode can be verified by checking the display.Three digits following the decimal point indicate that theunit is in 0 to ±1.999 kV range. Two digits following thedecimal point indicate that the sensor is in 0 to ±19.99kV range. To change between measurement ranges, press the RANGE/HOLD button once, momentarily.HOLD Function: in the event that the user wishes to freeze the current measurement, the HOLD function of the Static Sensor 718 may be used. Simply press the HOLD switch momentarily and the currently displayed voltage will be frozen. A HOLD notice will also bedisplayed to alert the user that the instrument is currently in HOLD status. To unfreeze the display and return tofloating measurement, momentarily press the HOLDswitch once again.Note: During HOLD condition the distance indicatingLED’s are turned off.Zero Adjustment: the SCS Static Sensor 718 has azero adjustment function, which sets a zero referencepoint for all subsequent measurements. This zeroreference can be set by pointing the instrument at aknown zero-voltage surface, and holding down the RANGE/ZERO button for longer than 3 seconds. After 3 seconds, the display will flash and adjust to zero. Repeat this step for both the low and the high ranges. The zero adjustment should be performed every time the unit is turned on.Measurement Accuracy: Distance Indicator: theStatic Sensor 718 is factory calibrated to give accurate measurements when it is placed one inch (2.54 cm) away from the object to be measured. To assist the user in gauging this distance, two light-emitting diodes (LED’s) are present on the front face of the instrument. These LED’s emit two red, bull’s-eye targets on thesurface of the object being measured. As the instrument gets closer to the one inch measurement distance, the bull’s-eyes begin to converge. When they converge and become one, the instrument is approximately one inch away, and the measurement can be made. For more accurate measurements, it is recommended that the user manually measure the distance between the front housing of the instrument and the object being measured.Accuracy and Size of Object to be Measured: the minimum surface area on an electrostatically chargedobject which can be accurately measured is a 5 squareinch (32.3 cm 2) area.Measurements from Greater than One Inch (2.54 cm) Away: in the event that a one inch separation between object-to-be measured and the Static Sensor 718 cannot be achieved, it is possible to get approximate readings.Continuous Output: an output jack is provided on the front of the SCS Static Sensor 718. This output can be used to feed a continuous signal into a data storage device for continuous monitoring of measured voltages. Please use a 3/32 inch (2.5 mm) mono-phone plug to connect into the output jack. The output signal is dependent on the measurement range currently selected. For the low range, the output signal is 1/1000 of the measured electrostatic voltage. For the high range, the output signal is 1/10,000 of the measured voltage.Figure 4. 718 Static Sensor showing hold function and Figure 5. 718 Static Sensor has a continuos output range.Figure 3. Using 718 Static Sensor to take measurements.Automatic Shut-Off: the Static Sensor 718 willautomatically shut-off 20 minutes after the last switch activity. This is done in order to conserve battery power. In the event that the user needs to have the unit stay ON continuously, when turning the unit on press the POWER AND RANGE switches simultaneously. This deactivates the Automatic Shut-Off feature. The BAT indicator will then flash three times to indicate that the automatic shut-off features has been disabled. The Automatic Shut-Off feature will reset itself the next time the instrument is turned on.Operation and Use of SCS Air Ionizer Kit 718A It is recommended that the user be familiar with ionizer test standards ANSI/ESD S3.1 and draft standard ANSI/ESD SP3.3 if the Air Ionizer Test Kit 718A is used to perform verification testing on ionizer performance.Assembly: slide the charge plate over the Static Sensor 718 until it stops. The charge plate slides onto the lower groove, on the sides of the Static Sensor 718.Charging the Plate: holding the Static Sensor 718 (with charge plate attached) in one hand, use the other handto touch the probe of the SCS Air Ionizer Test Kit 718Ato the charge plate. Press either the + button (for apositive voltage) or the – button (for a negative voltage), then remove the probe from the charge plate. Be sureto keep the button pressed while removing the probefrom the charge plate. The display on the Static Sensor 718 will indicate a positive or negative charging voltage (1.1kV minimum). If a voltage of less than ±1.1kV is displayed, check to see if the low battery indicator on the SCS Charger 718A is illuminated. If illuminated, replace the battery in the charger. If the unit continues to supply an incorrect voltage to the charge plate, please contact SCS for additional instructions.Testing ionizer discharge time: after charging the plate, hold the SCS Static Sensor 718 approximately one foot (30.5 cm) away from the ionizer. Monitor the display to see how quickly the 1.1 kV charge is dissipated to 0.1 kV. The speed at which this occurs (the discharge time) indicates how well the ionizer is operating. Please referto the specific ionizer’s operating manual or consultwith the ionizer manufacturer to determine what thisdischarge time should be. Repeat this procedure for both a positively and a negatively charged plate.Testing Ionizer Discharge Time: after charging theplate, hold the SCS Static Sensor 718 approximately onefoot (30.5 cm) away from the ionizer. Monitor the displayto see how quickly the 1.1 kV charge is dissipated to 0.1 kV. The speed at which this occurs (the discharge time) indicates how well the ionizer is operating. Please refer to the specific ionizer’s operating manual or consult with the ionizer manufacturer to determine what thisdischarge time should be. Repeat this procedure for botha positively and a negatively charged plate.Testing ionizer offset balance: zero the charge plateby touching it with a grounded object. This can either be the finger of a grounded person or some other item which is connected to electrical ground. In either case, zeroing the charge plate should make the display on the Static Sensor 718 read zero. Hold the Static Sensor 718 approximately one foot (30.5 cm) in front of the ionizer. Monitor the display. The value displayed is the offset balance of the ionizer, which is the difference between the number of positive and negative ions being emitted. Please refer to the specific ionizer’s operating manual or consult with the ionizer manufacturer to determine what this offset balance should be.Service/Calibration Service and Repair: in the event that you believe the Static Sensor 718 or the SCS Air Ionizer Test Kit 718Ais in need of repair, please contact your local SCS representative for troubleshooting help, and, as needed, repair information. There are no user-serviceable parts on either product. Figure 6. 718 Static Sensor charging plate in use.Figure 7.

防爆型静电电压表
防爆型静电电压表一、工作原理静电主要是指不同物体紧密接触并迅速分离，由于两种物体对电子约束能力不同，物体间发生电子转移，从而使物体分别带上不同种电荷的现象。
产生静电的原因既有物体内部原因，又有外界作用。
从而又分成摩擦带电、附着带电、感应带电、极化带电等情况。
本仪器使用大规模集成电路将模拟量转化为数字量在液晶显示器上显示。
二、应用范围可能存在静电的作业有：1)石油、化工、粮食加工、粉末加工、管道输送气体、液体、粉尘等。
2)气体、液体、粉尘的喷射（冲洗、喷漆、泄露）。
3)皮带输送。
4)物料搅拌、混合、过滤等。
5)高速行驶的交通工具。
6)人体静电（行走、脱衣、梳理毛发、用有机溶剂洗衣等）。
在一些具有可燃性气体或粉尘的场所，静电是绝对要禁止的，而静电又往往无法发现和感觉到，对于管道或皮带的输送、物料的搅拌或人体上产生的静电，是我们日常检查的重点之一。
另外，在怀疑是静电火灾时，也需要对怀疑可以产生静电的同类物质进行测量，以便确认产生静电的可能性。
三、静电火灾产生的条件1)现场要有能够产生静电的条件。
2)静电的积累足以产生放电的能量。
3)具有带电体放电的条件如放电对象、放电距离。
4)放电能量大于被引燃物的最小点火能量。
5)放电点周围存在处于爆炸极限范围内的混合性气体或粉尘。
上述静电火灾判定条件中，有的又取决于许多因素，故要分别进行讨论。
四、仪器特性量程：0~±30KV（测量距离2cm）●精度：±10%●分辨率：10V●功耗：≤30mw五、仪器使用方法1)打开电源开关，接通电源；2)距离带电体30cm以上处按调零开关调零，消除感应屏上的静电。
3)将电压表探头由30cm处靠近被测物体规定的距离处，读取电压值（为液晶显示值×10）；4)不要用手去触摸感应屏，以免损坏输入器件。
5)液晶显示器数字暗淡，显示不稳定或测试数据不准确，应检查9V积层电池，当电压低于8.8V或使用半年以上时应更换电池。
