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.
