two functions; when pressed momentarily it switches between 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 System
Included 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).
Hand-held static sensor locates and measures static voltages, tests air ionizers.
New from 3M, the 718 Static Sensor can help companies competing in the global high-tech marketplace prevent costly 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 surfaces arising from electrostatic charge buildups, and can help identify ESD trouble-spots — ensuring product reliability and customer satisfaction which translates into company profits. As a bonus, when used in conjunction with the 3MTM 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 and weighs less than 5 oz. (142 g), including battery. The lightweight plastic housing is conductive, allowing a properlygrounded user to dissipate all electrostatic charges from the surface of the meter.
Meter Functions
The meter is equipped with three membrane switches which control different functions. The POWER switch turns the instrument on and off. The RANGE/ZERO button performs

Accuracy
The 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 distance between measured object and instrument changes from the one inch (2.54 cm) specification.
Analog Output Jack
The analog output jack located in the front of the unit provides 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.
