6. Touch the electrode to the bare ground wire or grounded
substrate of the part being inspected.
7. The PosiTest HHD C audible and strobe alerts should
activate.
NOTE:
8. Release the trigger to turn high voltage OFF and return the
PosiTest HHD C to Standby Mode, then remove the
electrode from the part being tested. Steps 5 – 8 can be
repeated several times.
WARNING:
electrode from the part under test. This ensures that the built-in
bleeder resistor will discharge the part being tested.
The PosiTest HHD C is now ready to use.
Adjusting the Test Voltage and Sensitivity
With the detector powered ON and in Standby Mode, the current
test voltage will be displayed. Press
following adjustment modes:
Adjust Test Voltage Use the
kV
the test voltage. The voltage can be adjusted in 10V increments
between 500V and 1,000V, and in 100V increments between 1kV
and 30kV. Press
Adjust to coating thickness (mils) Use the
mils
buttons to set your expected coating thickness in mils. Press
accept and exit. The test voltage will be calculated according to the
equation below.
Adjust to coating thickness (microns) Use the
μm
buttons to set your expected coating thickness in microns. Press
to accept and exit. The test voltage will be calculated according to
the equation below.
V = 1,500 + 1.5[170 + 2.48d + 58√d] (microns)
V = 1,500 + 1.5[170 + 63d + 293√d] (mils)
where
V = Voltage in volts
Always release the trigger before removing the
