2. Attach ground clamp to a proven earth ground.
For Guns
3. If measuring the voltage on an electrostatic
gun, line up the hole in the test probe and the
electrode. Slide the test probe straight over the
electrode wire of the gun. Be sure to push the
test probe tight against the nozzle to minimize
any voltage that may leak into the air during
the test.

To provide proper equipment to operator
ground, the conductive handle of the probe
MUST
be held in the bare hand of the op-
erator. To avoid a shock hazard, the meter
should
NEVER
be disconnected fromthe
probe during high voltage contact.
These operating instructions MUST be read and
thoroughly understood by all personnel who use
this equipment. Special care should be taken to
ensure that all Warnings and Requirements for
operating the equipment safely are followed.
The user should be aware of and adhere to all
relevant local and company safety and fire codes
and ordinances and the Occupational Heath Act
of 1970 (OSHA) prior to operating this equipment.
1. Set the meter dial to the kV scale (see Figure 7).
Plug the high voltage probe into the side of
the meter.

Electrostatic AIr Spray Gun
4. Holding the metal part of the high voltage probe
in your hand, trigger the gun so voltage exists
at the electrode.
5. Read the voltage displayed on the meter in 30
seconds or less.
6. Turn the voltage to the gun OFF, and pull the
test probe straight off the electrode.
For Bells or Disks
7. Turn the high voltage power supply on.
8. Make and maintain sure contact between the
test probe and the applicator (see Figure 8).
Make sure all grounded objects are
at least 2 feet away.
NOTE
Ensure that the applicator is
NOT
rotating
when contacting it with the probe. Also, to
get proper readings on resistive applicators,
the probe must be placed in contact with the
atomizing edge of the bell or disk as shown
in Figure 8. As this edge is sensitive to me-
chanical damage, use care when contacting
it with the probe. Rough handling may cause
damage to the applicator.
