To avoid possible electric shock, instrument damage and/or
equipment damage, do not attempt to take any voltage
measurements if the voltage is above 600 V AC/DC are the
maximum voltages that this instrument is designed to measure.
The “COM” terminal potential should not exceed 600 V measured
to ground.
4. Plug the red test lead into the V/Ω-Input jack on the meter and
connect the circuit where a voltage measurement is required.
Voltage is always measured in parallel across a test point.
5. Turn on power the circuit/device to be measured and make
the voltage measurement reduce the range setting if set too
high until a satisfactory reading is obtained.
6.2. Current Measurements
WARNING! These Snap-arounds are designed to take current
measurements on circuits with a maximum voltage difference of
600 V AC between any conductor and ground potential. Using the
snap-around for current measurements on circuits above this
voltage may cause electric shock, instrument damage and/or
damage to the equipment under test. Before measuring current
make certain that the test leads are removed from the instrument.
The snap-around is overload protected up to 600 V AC for up to 1
Min. Do not take current readings on circuits where the maximum
current potential is not known. Do not exceed the maximum
