Operation
Safety
Testing
If the coating has been applied recently, it should be cured in
accordance with the manufacturers instructions before
testing.
In the absence of manufacturers instructions the coating
should be cured for at least 10 days.
The surface of the coating should be free of oil, dirt and other
contaminants before testing.
The Holiday Detector must be switched off and the multiturn
voltage control turned fully anticlockwise.
Connect the plugs on the High Voltage Handle and Earth
Cable to the colour coded sockets on the front and back of the
instrument.
Fit the required Brush or Rolling Spring to the High Voltage
Handle.
Connect the Earth Cable to the base metal of the item under
test. It is essential that the base metal of the item being
tested is also connected to a true earth.
Switch the Holiday Detector on to switch position A.
The green fault indicator will illuminate and there will be a low
reading on the display.
Press the switch on the High Voltage Handle and turn the
multiturn voltage control on the instrument in a clockwise
direction until the required test voltage is displayed.
Test Voltage
The test voltage should be set in accordance with the coating
manufacturers instructions.
In the absence of manufacturers instructions the test voltage
table shows the test voltage required for the testing of the
coating thickness in compliance with ISO 29601.
The Holiday Detector can be used on coatings above 300
microns in compliance with ISO 29601.
The 0.5 to 6kV Holiday Detector (S4001) can be used on
coatings above 100 microns.
Replacing Batteries
When the batteries require replacement, the red Lo Bat
indicator will illuminate.
To replace, pull out the 2 drawers located on the rear of the
instrument.
Replace with 2 lithium PP3 batteries, ensuring correct polarity.
