3． If the mains warning LED lights and/or the buzzer sounds DO NOT
PRESS THE TEST BUTTON but disconnect the instrument from the
circuit. Make the circuit dead before proceeding.
4. Press the test button when the display will show the insulation resistance
of the circuit or the appliance to which the instrument is connected.
5. Note that if the circuit resistance is greater than 20MΩ the instrument will
automatically range to the 200MΩ reading.
6. When testing is complete release the test button BEFORE disconnecting
the test leads from the circuit or from the appliance. This will ensure that
the charge built up by the circuit or the appliance during insulation test
is dissipated in the discharge circuit. In the discharging process, an LED
illuminates and the live circuit warning buzzer will sound.

CAUTION
NEVER TURN THE FUNCTION DIAL WHILE THE TEST BUTTON IS
DEPRESSED AS THIS MAY DAMAGE THE INSTRUMENT. NEVER
TOUCH THE CIRCUIT, TEST LEAD TIPS OR THE APPLIANCE
UNDER TEST DURING INSULATION TESTING.
Note： If the reading measured greater than 200MΩ the over range reading
"OL" will be displayed.
At 1000V range, the buzzer sounds during testing (being pressed or
locked down the test button).
