Rules For Safe Operation (1)
l
Before using the Meter inspect the case. Do not
use the Meter if it is damaged or the case (or part
of the case) is removed. Look for cracks or
missing plastic. Pay attention to the insulation
around the connectors.
l
Inspect the test leads for damaged insulation
or exposed metal. Check the test leads for
continuity. Replace damaged test leads with
identical model number or electrical specifications
before using the Meter.
l
Do not apply more than the rated voltage, as
marked on the Meter, between the terminals or
between any terminal and ground. If the value
to be measured is unknown, use the maximum
measurement position and reduce the range step
by step until a satisfactory reading is obtained.
l
When measurement has been completed, disconnect
the connection between the test leads and the
circuit under test, remove the
test leads from the
input terminals of the Meter and turn the Meter
power off.
l
The rotary switch should be placed in the correct
position and no change of range made during
measurement, to prevent damage to the Meter.
l
Do not carry out the measurement when the
Meter’s back case and battery compartment are
not closed to avoid electric shock.
l
Do not input higher than 600V between the Meter’s
terminals and the ground to avoid electric shock
and damage to the Meter.
