PosiTest HHD C Troubleshooting
Check Electrode Connections: With the detector powered OFF,
PosiTest HHD C will not detect holidays
check all connections. Ensure the electrode is fully engaged
within the electrode collar of the PosiTest HHD C and the thumb
screw is secured.
Check Ground Connections: With the detector powered OFF,
remove the ground cable and then fully reinsert it into the ground
socket. Finger tighten the nut by turning clockwise. Ensure the
opposite end is clean and well connected to the substrate of the
coating system being inspected.
Check Test Voltage: If the test voltage is too low, the PosiTest
HHD C will not find holidays.
Reduce Travel Speed: Recommended travel speed of the
PosiTest HHD C is a maximum of 0.3m/second (1ft/second).
Check Batteries: Low or defective batteries will not be able to

actual voltage being generated (± 5%). Although the PosiTest
HHD C will regulate the output voltage to match the test voltage,
there are circumstances when it is not possible to generate the
test voltage. For example, overloading of the electrode by setting
the voltage higher than recommended for the coating system
under inspection may result in a generated voltage lower than the
test voltage. Reducing the brush or electrode size will also reduce
loading.
The PosiTest HHD C meets the Electromagnetic
Compatibility Directive and Low Voltage Directive
when operated in Standby Mode.
