This instrument can play a valuable role in an organization's ESD-control program ensuring product reliability and customer satisfaction which translates into company profits. As a bonus, when used in conjunction with the 3M™ Model Air Ionizer Test Kit 718A, the 718 can also be used to verify the operation of air ionizers.
 

 

Convenient Size/Low Power Requirements
 

The 718 is small enough to be carried in a pocket and weighs less than 142 g, including battery. The lightweight plastic housing is conductive, allowing a properly-grounded 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 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 Static Sensor 718 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 2.54cm.
 

Accuracy
 

The Static Sensor 718 is accurate to within +/- 5% of the displayed measurement, at a distance of 2.54 cm from the target. Accuracy will vary as the distance between measured object and instrument changes from the 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 2.5 mm monophone jack, to a recorder/data acquisition console. The Static Sensor 718 may then be used for remote monitoring or permanent recording of electrostatic voltage readings.
