† If these are bad, the applicator most
likely will not rotate because the atomizer
card will shut the air to the turbine off.
HIGH VOLTAGE TEST
In-Direct Charge Test (70kV
Maximum)
1. Install the High Voltage Cable to the High
Voltage Ring and Cascade as prescribed in the
applicator service manual. Ensure all components
are properly grounded.
2. Install the ground cable into the HV/GND port
of the mounting manifold.
3. Turn on the main power to the Micro Pak.
Display should be reading 00 on the kV and µA
display.
4. Turn on the kV enable switch. kV should be
reading what has been set by adjusting the dial.
5. Using the High Voltage probe (76634-00) check
the actual voltage from the High Voltage Ring by
placing the High Voltage Test Probe on the High
Voltage Ring Probe tips. Test Probe display
should match the Micro Pak display.
6. Turn off the power supply to the MicroPak.
Direct Charge Test (90 kV
Maximum)
1. Install the High Voltage Cable to the applica-
tor and Cascade as prescribed in the applicator
service manual. Ensure all components are
properly grounded.
2. Turn on the main power to the Micro Pak.
Display should be reading 00 on the kV and µA
display.
3. Turn on the kV enable switch. kV should be
reading what has been set by adjusting the dial.
4. Using the High Voltage Probe (76634-00)
check the actual voltage from the High Voltage
Ring by placing the High Voltage Test Probe on
the bell cup. Test Probe display should match the
Micro Pak display.
5. Turn off the power supply to the MicroPak.

low 5K RPM.
C A U T I O N !
† During any part of the turbine tests
where the applicator bell is rotating, DO
NOT come near or in contact with the spin-
ning bell. Because of the bell rota-tional
speed, injury can easily occur. Locate the
bell in a posiiton where mini-mal exposure
to anyone passing by may come in contact
with the spinning bell.
† NEVER use any fluid other than distilled
or de-ionized water to test the applicator
performance. Using any other material will
cause a risk of fire or severe personal injury.

† DO NOT use your hand or any object to
stop bell cup rotation.
