CAUTION!
Do not attempt to make a current measurement with the test
leads connected in parallel with the circuit to be tested. Test
leads must be connected in series with the circuit. Do not
attempt to make a current measurement of circuits with more
than 600V present. Instrument damage and/or personal injury
may result. Make sure the temperature probe is NOT plugged
in during this test.
