DIGITAL + ANALOGUE HIGH VOLTAGE INSULATION TESTER
OPERATOR’S MANUAL
OPERATING INSTRUCTION
4.4.6 Loosen the button after the measurement, wait several seconds and then disconnect the test line
from the tested circuit, which is to release the charge stored in the circuit tested.
ATTENTION
Due to huge power consumption in the measurement, continuous measurements for long time should be
avoided.
WARNING
Never touch the circuit under test during insulation measuring.
Never rotate the range switch while the test button is pressed. This may damage the meter.
When measuring is complete ensure that the test button is released before the test clips are
disconnected. This is because the system may be charged up and it must be allowed to
discharge through the tester's internal discharge resistor.
