The PosiTest HHD C powers-up when the power button
pressed. To preserve battery life, it powers down after approximate-
ly 5 minutes of no activity. Alternatively, hold the power button
for 5 seconds for immediate power down. All settings are retained.
1. Review Operational Safety (pg. 1).
2. Assemble the detector for the application to be tested –
"Assembly Instructions" (pg. 5).
3. Properly ground the instrument – "Grounding" (pg. 5).
4. Confirm that the detector is in proper working condition –
"Operational Check" (pg. 5).
5. Verify and Set the test voltage and sensitivity – "Adjusting the
Test Voltage and Sensitivity" (pg. 6).
6. Perform the test – "Instrument Operation" (pg. 7).
The PosiTest HHD C has two primary operating modes:
1. Standby Mode: The detector is powered up but not generating
a high voltage. The detector continuously monitors the electrode
voltage, and will display the voltage and lightning bolt icon
voltages over 500 Volts are present on the electrode. DO NOT
touch the electrode or surface if the lightning bolt icon
on the display.
2. Detection Mode: The detector is generating a high voltage and
analyzing electrode voltage and current to determine if holidays
are present. Holidays can be detected when the charged
electrode is passed over a coated substrate. When a holiday is
encountered, current flows from the electrode into the substrate.
The current returns to the detector through the ground (earth)
wire, completing the circuit and triggering audible and visible
alarms. An integrated voltmeter measures and displays the
electrode voltage on the display while in use.
After the trigger is released the detector returns to Standby
Mode. The electrode voltage and lightning bolt icon will continue
to be displayed until the electrode and surface have discharged.
DO NOT touch the electrode or surface if the lightning bolt
shown on the display.
