Operation
Testing the Gun While It is
Operating
NOTE:
The maximum voltage read by the kV meter and
probe may be less than the rated voltage of the gun or
power supply that you are testing. This is due to voltage
losses that are intrinsic to the measurement of high volt-
age in air. These losses include current draw through
the probe and meter and also the inability to capture
100% of the electrons being emitted by the gun elec-
trode.
1.
Connect the probe’s red wire (D) to the kV meter (2)
and its green/yellow ground wire (C) to a true earth
ground (B). See F
IG
. 1.
2.
Connect the kV meter’s green/yellow ground wire
(6) between the kV meter (2) ground connection and
a true earth ground (B).
3.
Holding onto the probe (3) handle, touch the end of
the probe to the spray gun electrode (A). Move the
end of the probe slightly until the maximum kV read-
ing is obtained.
4.
Read the voltage on the kV meter (2). Refer to
Table 1 for your gun model.
NOTE:
When the kV meter (2) is not in use, place a
jumper wire across the kV meter connectors to prevent
excessive needle movement.

WARNING
Pressurized Equipment Hazard
Before testing the gun, follow the
Pressure
Relief Procedure
in your gun manual to
reduce the risk of fluid injection or splashing
of fluid in the eyes or on the skin.
