Operation

Connecting Test Leads

For all measurements connect the red test lead to the VΩ input terminal and the black test lead to

the COM input terminal.

Test Lead Check

1. Set the rotary switch to the Ω range.

2. Touch the test lead tips together.

3. Resistance should read less than 0.5Ω and the audio tone should sound.

4. With the leads not touching, the display should read OL indicating over-range.

5. Readings displayed other than the readings described above are evidence of a problem and

the test leads must be replaced before using the meter. Failure to do so could result in damage

to equipment and electrical shock. If replacing the test leads does not solve the problem, return

the instrument for repair.

Warning

Ensure that the circuit under test does not include components that can be damaged by 1000VDC; such

devices include power factor correction capacitors, low voltage mineral insulated cables, electronic light

dimmers, and ballasts/starters for fluorescent lamps.
