Description

The SCS Static Sensor
instrument used for locating and measuring electrostatic
charges. It can be used to locate ESD trouble-areas, and
is a valuable tool for the ESD-control engineer. Used in
conjunction with the SCS Air Ionizer Test Kit
separately), it can be used for verification and auditing
of air ionizers. The Static Sensor 718 is battery-powered
and has several measurement features:
Range: measurements can be taken in a 0 to ±1.999 kV
or 0 to ±19.99 kV range.
Automatic Zero: push button feature allows easy
adjustment to zero. No screws or dials to turn.
HOLD function: allows the User to "freeze" a displayed
measurement, for later evaluation.
Automatic shutoff: conserves battery power by shutting
off the instrument after 20 minutes of inactivity.

Power Requirements and Battery Installation

1. Both the Static Sensor 718 and SCS Charger 718A
use a 9V alkaline battery.
2. To install the battery on either unit:
3. Remove the battery cover, located in the lower back
of the unit. To do this, press down on the cover and
slide it downward.
4. Pull the battery connector out of the housing, and
align the male/female ends of the connector with the
proper terminals on the battery.
5. Connect the two and place the connected battery
into the housing by inserting the connector end first,
then following up with the other end of the battery.
6. Replace the cover.

7. The SCS 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.
8. The SCS 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 should replace the battery. Usage of the
Charger 718A under low battery conditions would
lead to insufficient voltage levels being generated.

Operation of the Static Sensor 718

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.
The SCS Static Sensor 718 is a precision electronic
instrument. Improper use or rough treatment can
damage the unit, and render it incapable of providing
accurate measurements.
Turning the unit ON and OFF: To turn on the Static
Sensor 718, momentarily press down on the membrane
switch labeled POWER. Determining that the power
is on can be verified by seeing that the liquid crystal
display (LCD) is on, and that the red light-emitting diodes
in the front of the sensor are lit.
