3M 718A, 718 User Manual

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
3MTMModel 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

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).

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.

3M™718A Air Ionizer Test Kit

When used with the 3M™718 Static Sensor, the 3M 718A
Air Ionizer Test Kit can provide periodic verification of air
ionizer performance. The 718A 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. Placing
the 718 in the air flow of an air ionizer allows for measure-

ment 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.
