4. Single Pole Voltage Indication
Perform a function test prior to this test.
This unit can be used as a single pole voltage
indicator when the batteries are inserted.
The single pole test is intended only as a quick
check. The circuit must be checked again for the
presence of voltage using the two-pole method.
Connect test probe L2 to the voltage source and
keep finger on the contact electrode (8). If an AC
voltage above 100 V is present the LED (4) is
illuminated and the buzzer sounds.
The single pole test can be negatively affected
by unfavourable conditions such as electrostatic
field, good insulation etc.
