Warning
These safety warnings are provided to ensure the safety of
personnel and proper operation of the instrument.
Read the following safety information carefully before attempting
to operate or service the meter.
Safety is the responsibility of the operator!
Tests are to be carried out only on dead circuits! Check for live
circuits before making resistance measurements.
The megohmmeter is a source of high voltage, as is the sample
connected to them. All persons performing or assisting in the
tests must employ all safety precautions to prevent electrical
shock to themselves and to others.
AEMC®considers the use of rubber gloves to be an excellent
safety practice even if the equipment is properly operated and
correctly grounded.
When testing capacitive samples, make sure that they have
been properly discharged and that they are safe to touch.
Electrical equipment and cables may have sufficient capacitance
to store a dangerous charge from the instrument test current.
For proper discharge to occur the push-to-measure button must
be in the OFF position with the lock OFF and with the sample
connected between the EARTH (+) and LINE (-) terminals.
On prolonged tests, the TEST button may be locked ON. Care
should be taken in this mode that no damage is done if the
instrument is left unattended.
Megohmmeters should never be used in an explosive
environment.
