6.3. Power Measurements
WARNING! These transformer jaws 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 clamps 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 transformer jaw 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.
1.
Set the Function Switch to 40kW or 240kW position.
2.
Connect the test leads to the voltage source in parallel with
load.
- Red test lead to the positive point (DC) or to the phase
conductor L1 (AC)
- Black test lead to the negative point (DC) or to the
neutral conductor N (AC)
