CURRENT MEASUREMENTS
WARNING
These Snap-Arounds are designed to take current measurements
on circuits with a maximum voltage difference of 500VAC 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 500VAC 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.
1.
Set the Function/Range switch to the
/
position.
2.
Press the trigger to open the transformer jaws and clamp them around
a conductor. Jaws should be completely closed before taking a
reading.
3.
The most accurate reading will be obtained by keeping the conductor
across center of the transformer jaws.
4.
The reading will be indicated on the display.
5.
Reduce the range setting if set too high until a satisfactory best
resolution reading is obtained.

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 al-
ways measured in parallel across a test point.
5. Turn on power the circuit /device to be measured and make the
voltage measurement reduse the range setting if set too high until a
satisfactory reading is obtained.
6. After complating the measurement, turn off power to the circuit /
device under test , dischange all capacitors and disconnect the meter
test leads.
