Adjustment and Maintenance
Rotating the Sensor Head
The 180-degree rotary head with 2.75
ʺ
x 1.25
ʺ
plate allows the operator to read the display at
various angles.
The sensor head rotates in 45-degree increments.
When rotating the head, stop at angles where the
sensor head clicks into place.
Battery Indicator
The remaining battery charge is displayed on the
lower left of the display panel.
Replace the battery when the icon shows only one
bar remaining.
Error Display
Er3 will appear on the display and a continuous
audible alarm will sound should the meter fail to
apply sufficient voltage onto the plate. This may be
caused by dirty or moist insulating spacers. Clean
and dry the insulating spacers to solve the error.
Contact Customer Service should the meter
continue to alarm after cleaning the insulating
spacers.
The Portable Charged Plate Monitor uses an
oscillating chopper to take measurements. Er9 will
appear on the display and a beeping audible alarm
will sound should the sensor stop oscillating.
Restart the meter should this occur.
Contact Customer Service should the meter
continue to alarm after restarting it several times.
