AC Current Measurement
IMPORTANT: Make sure that all test leads are disconnected from the meter
Note: This mode is typically used in commercial or industrial installations and is not functional
for standard domestic AC cables which have an insulated sleeve covering individually
insulated live and neutral conductors. Do not remove important safety insulation in order to
take a measurement.
1. Rotate the Dial (4) to the 1000A~ setting, as shown approximately bottom left on Fig. I
2. Make sure the Data Hold Button (3) is not pressed
3. Press in the Clamp Lever (10) to open the Clamp (1) and insert one conductor ONLY into
the Clamp Area (2) (Fig. II). It is impossible to make measurements when two or three
conductors are clamped at the same time
4. If the display indicates one or more leading zeros, shift to the 200A~ range to improve the
resolution of the measurement
5. Allow a few seconds for the reading to stabilise. To read the display more clearly, push in
the Data Hold Button, unclamp the conductor and move the meter to a more convenient
location
AC Voltage Measurement
1. Set the Dial (4) to the 750V~ position. Do not use the meter if you are unsure whether the
voltage exceeds 750V.
2. Connect the probes to the circuit under test in parallel and take the reading
DC Voltage Measurement
1. Set Dial (4) to the 1000V⎓
2. Do not use the meter if you are unsure whether the voltage exceeds 1000V
3. Connect the probes to the circuit under test in parallel and take the reading. A '-' will
precede a negative value in the LCD Display (9)
IMPORTANT: Disconnect circuit power and discharge all capacitors before testing resistance
and continuity.
Resistance Measurement
1. Set the Dial (4) to 200Ω or 20kΩ position
2. Connect test lead probes to the circuit or cable to be tested and take the
resistance reading
• With the test lead probes open the LCD Display (9) should indicate '1'
(over range)
• Connecting the Positive/Live Probe (12) and Negative/Common Probe (13) together will
indicate '0.00' on the LCD Display
Continuity Check
This allows fast checking of continuity using an audible buzzer.
1. Set the Dial (4) to 200Ω position
2. Connect the test lead probes to the circuit or cable to be checked for continuity
• For resistance readings:
50Ω or less - the buzzer will sound
50 - 100Ω - the buzzer may not sound
100Ω or greater resistance - the buzzer will not sound
Insulation Resistance Test
• Follow the instructions provided with the Insulation Tester
Troubleshooting
Problem

Intermittent connection in one of the test leads
Battery low
Maintenance
Cleaning
• Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives
or solvents
• Dirt or moisture in the meter sockets and test lead connectors can affect readings. To
clean remove any loose dirt/debris first and then use a cotton bud dipped in neat alcohol
cleaning fluid. Work the cotton bud around the full area of each connector and socket.
Storage
Switch off the meter and disconnect the test leads. Refit the Test Lead Connector Covers (11)
and store meter, test leads and these instructions in the supplied case. For long-term storage,
remove the battery.
Disposal
Always adhere to national regulations when disposing of tools that are no longer functional
and are not viable for repair.
• Do not dispose of waste electrical and electronic equipment (WEEE), with household waste
• Contact your local waste disposal authority for information on the correct way to dispose
of tools
