718 Static Sensor

718A Air Ionizer Test Kit

two functions; when pressed momentarily it switches between the two measurement ranges of 0-2,000volts and0-20,000volts, 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 718 Static Sensor is a ranging system consisting of two light-emittingdiodes (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).

3M 718 Static Sensor

Hand-heldstatic sensor locates and measures static voltages and tests air ionizers.

The 3MTM 718 Static Sensor can help companies competing in the globalhigh-techmarketplace prevent costly losses due to electrostatic discharge (ESD) damage by playing a vital and valuable role in their own ESD control program. Easy to use, thehand-held718 Static Sensor is designed to measure static voltages on objects and surfaces arising from electrostatic charge buildups, and can help identify ESDtrouble-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 properly-groundeduser 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 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 718 Static Sensor may then be used for remote monitoring or permanent recording of electrostatic voltage readings.

3M 718A Air Ionizer Test Kit

3MTM 718A Air Ionizer Test Kit

When used with the 3MTM 718 Static Sensor, the 3MTM 718A Air Ionizer Test Kit can provide periodic verification of air ionizer performance. The 718A Air Ionizer Test Kit consists of a charge plate and a charger. The system as a whole is designed to meet the guidelines specified in ESD Association Draft Standard D3.3.

The charge plate slides over the housing of the 718 Static Sensor. Placing the 718 in the air flow of an air ionizer allows

for measurement of the ionizer’s offset balance. The charger can be used to deposit an electrostatic charge on the plate. Measuring how long it takes the ionizer to neutralize this static charge gives the ionizer discharge time.

Calibration and Certification

The 3M 718 Static Sensor can be ordered as calibrated and certified by a 3M ISO9002 Registered Metrology Laboratory. Calibration can be traced back to National Institute of Standards and Technology (NIST) standards, as specified in MIL-STD-45662.
