2. Operation
2-1. Battery Installation:
 Open battery compartment door on the back
of the Fieldmeter.
 Connect battery to the wire terminal.
 Replace and close battery compartment door.
2-2. Power button
Press “POWER” button once. The unit will be
in static charge measurement mode or standard
mode.
2-3. LCD Display.
 The upper left section displays a bar graph
in blue to indicate negative polarity
voltage.
 The upper right section displays a bar
graph in red to indicate positive polarity
voltage.
 The lower section displays reader friendly
numerical values, voltage unit, functions in
use, and battery condition.
Note:
 If the voltage reading is blinking ±22.0
kV with a continuous warning sound,
the maximum voltage reading limit
has been exceeded.
 If the voltage reading is Err, the
maximum voltage reading limit has
been continuously exceeded and the
sensor could be damaged.
2-4. Battery Condition Display.
 The battery condition icon has 4 display stages.
Replace the battery when display shows the
battery to be empty.
 The life of a 9V battery, is approximately 30
hours.
2-5. Fieldmeter sound notifications.
 1 beep – turned on and standard mode
 3 beeps – turned on without auto power off function.
 5 beeps – auto power off notification.
 1 long beep – over range notification.
2-6. Ground the Electrostatic Fieldmeter.
 Plug ground wire into the ground wire jack in the
side of the fieldmeter.
 Connect to an earth ground using the alligator
clip.
Note: for an accurate measurement, make sure the
fieldmeter is connected to ground.
2-7. Proper Distance from target.
The distance between the fieldmeter and the target
needs to be 1 inch (25.4mm). This is done by using the
LED’s. When the two red lights converge as one
concentric circle the fieldmeter is at the proper
distance.
