Continuous Output: an output jack is
provided on the front of the 3M
™
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.

Automatic Shut-Off: the Static Sensor 718 will automatically 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.
4.0 Operation and Use of the 3M
™
Air Ionizer Test 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.
4.1
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.
4.2
Charging the plate: holding the Static Sensor
718 (with charge plate attached) in one hand,
use the other hand to touch the probe of the
3M
™
Air Ionizer Test Kit 718A to the charge
plate. Press either the + button (for a positive
voltage) or the – button (for a negative voltage),
then remove the probe from the charge plate.
Be sure to keep the button pressed while
removing the probe from the charge plate.
The display on the Static Sensor 718 will
