2.3 The 3M
™
Static Sensor 718 has a Low Battery
indicator. Once the battery is depleted to
approximately 6.5 volts, the instrument will
show BAT in the display. At this time, the
Static Sensor 718 will not produce accurate
results and the battery should be replaced.
2.4 The 3M
™
Charger 718A also has a low battery
indicator. This is an LED located at the left-
hand side of the unit. When the battery voltage
drops below operating level, the LED will light
up. At this time, the user shouldreplace the
battery. Usage of the Charger 718A under low
battery conditions would lead to insufficient
voltage levels being generated.
3.0 Operation of the Static Sensor 718
Supplemental notes:
For accurate measurements during
usage, it is recommended that the
outside housing of the Static Sensor
718 be connected to an electrical
ground. This can be accomplished
by having the user holding the instrument
connected to ground through either a static
control wrist strap, or while wearing static
control footwear. The enclosure of the
Static Sensor 718 is made of conductive
plastic and is, therefore, electrically
connected to whomever is holding the instrument. In addition, ground for the
instrument can be provided through the Voltage Monitor Output on the front of
the case.
