Operation

AC Current Measurement

1. Set the Range Selector Switch to the

proper range (20, 200 or 600 ACA).

Note: If measuring an unknown current,

start at the highest range, then

adjust to the proper lower range

for best resolution.

2. Press the trigger to open the jaws.

Clamp around one conductor only.

Make sure that the jaws are firmly

closed around the conductor.

3. Read the value on the digital display.

Press DATA HOLD to hold displayed

value. Press again to release.

Electrical Shock Hazard.

Contact with live circuits will result in severe injury

or death.

AC Voltage Measurement

1. Connect the red test lead to the + input terminal and the black test lead to the

- input terminal.

2. Set the Range Selector Switch to the proper range (250V or 750V).

Note: If measuring an unknown voltage, start at the highest range, then adjust to

the lower range for best resolution.

3. Connect the test leads across the source or load being measured and read the

display. Press DATA HOLD to hold displayed value. Press again to release.

Note: Voltage reading should always be taken in parallel with the circuit.

Electrical Shock Hazard.

Contact with live circuits will result in severe injury

or death.

Resistance Measurement

1. Turn off device being tested. Discharge any capacitors. Voltage should not be

present.

2. Connect the red test lead to the + input terminal and the black test lead to the

- input terminal.

3. Set the Range Select Switch to the 2KΩResistance Range.

4. Connect the test leads across the resistance being measured and read the

display. Press DATA HOLD to hold displayed range. Press again to release.

Note: Resistance readings should always be taken in parallel with the circuit.

Never connect a source of voltage with the Range Selector Switch in the

Ω(ohms) position. Personal injury or damage to the meter may result.

Failure to observe this warning may result in severe injury or death.
