4. Plug the red test lead into the V/-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. After completing the measurement, turn off power to the
circuit/device under test, discharge all capacitors and
disconnect the meter test leads.
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 current that this instrument is designed to measure.
