VII. BASIC OPERATION WHILE USING THE ONE (1) INCH RETRACTABLE SPACER
The retractable spacer is provided to conveniently define the measurement space between
the front sensing end of the instrument case and the measurement target. The spacer is
made of a low charge generating, somewhat insulative material. It is designed to avoid
discharging the measurement target surface if touched by the spacer, and minimize
influence of the electrostatic field measurement.
A. While holding the ACL 350 in one hand, discharge your body by touching a
grounded conductive object.
1.
The operator may wear a grounded wrist strap or place a grounded wrist
strap cuff around the instrument case beneath the display and operating
buttons.
2.
The case of the instrument is conductive and is the reference for
measurement.
B. Press the POWER ON/HOLD button and release.
C. Face the static locator away from charged objects and depress and release the
ZERO button twice. Note that the display indicates 00.0 volts.
D. Rotate the one inch spacer 180
o
from its
storage configuration such that it extends
beyond the front sensing end of the case,
and is on a parallel plane with the case.
E. If the display indicates a measurement
other than 00.0, repeat the ZERO
procedure above. This will compensate for
any small charge on the spacer.
F. Point the sensor plate toward the target and move to a point one inch from the
surface to be measured such that the
spacer is virtually in contact with the
target material. At this point, there is a
one inch space between the front
sensing end of the case and the target.
