Always check for voltage before testing and measuring on
a circuit. This instrument is intended for measuring Low Ω and
Insulation resistance on unenergized circuits only.
Use the procedure explained at points 9.2, 9.3, 9.4.
Connect the test leads to the circuit to be measured and wait
for a few seconds. The instrument will automatically discharge
any remaining energy which could be present on the circuit,
and will check for voltage at the same time.
Once you are sure that the circuit to be tested is not energized,
then press the button for a short test duration or press and
turn the button for a long test.
Once you end the test, allow a few seconds for the
instrument to automatically discharge the circuit
