MAKING MEASUREMENT

1. Use the proper function and range for measurements.
2. To avoid possible electrical shock, personal injury or damages to the
Tester, disconnect circuit power and discharge all high-voltage capacitors
before testing insulation resistance and continuity.
3. Connecting test leads:
• Connect PE test lead (green) to the circuit before connecting the live leads;
• After measurement, remove live leads before removing PE test lead
from the circuit

Measuring AC Voltage

• To avoid personal injury or damage to the tester, do not apply voltage
higher than 440V.
• Connecting test leads:
- Connect COM test lead (black) to the circuit before connecting the live leads;
- After measurement, remove live leads before removing COM test lead
from the circuit
To measure voltage and frequency:
1. Turn the rotary switch to Volts position.
2. Use red and black (V – COM) terminals for this test. You can use test
leads or 3-wire mains test cord when measuring AC voltage.
The primary display shows the Voltage.
The secondary (smaller digits on the right side) display shows the Frequency.

Measuring Insulation Resistance

• Make sure disconnecting circuit power and de-energize the circuit before test.
• When measuring insulation resistance, make sure test leads are separated
and are not twisted together.
• Do not short circuit two test leads when output DC voltage presents at
the output terminals.
• Do not measure insulation resistance at live high voltage circuit.
• Do not carry out measurement when the battery compartment is open or
accessible.

11
• When the measurement is completed, do not touch the circuit as the
circuit may store energy, which may cause electric shock. Allow time for
circuit to discharge
• Warning buzzer will sound when the Tester detects a voltage >30Vac or
dc. Display shows symbol and the detected voltage.
Figure 3: Tester detects a voltage >30Vac
Figure 4: Tester detects a voltage >30Vdc
To measure voltage and frequency:
1. Turn the rotary switch to Insulation position (250V, 500V, or 1000V).
2. Use the red and black (L – N) terminals for this test with test leads.
3. Press F1 to activate , buzzer will sound when resistance < 2MΩ.
4. Press F2 to activate Test Lock mode for continuous measurement.
Note: Testing is inhibited if voltage is detected in the circuit under
measurement.
5. Press TEST button to begin measurement.
The primary display shows the insulation resistance.
The secondary (smaller digits on the right side) display shows the actual
test voltage.

Measuring Continuity

• Disconnect circuit power and de-energize the circuit before test.
• Do not measure continuity at live high voltage circuit.
• Do not carry out measurement when the battery compartment is open
or accessible.
• Warning buzzer will sound when the Tester detects a voltage >30Vac or
dc. Display shows symbol and the detected voltage.

13
Figure 6: Tester detects a voltage >30Vac
Figure 7: Tester detects a voltage >30Vdc
To measure continuity:
1. Turn the rotary switch to Continuity position.
2. Use the red and black (Ω– COM) terminals for this test with test leads.
3. Before making a continuity measurement, use ZERO function to zero
the test leads.
Test lead resistance zeroing:
Step 1: Connect test leads to Ωand COM terminals and short-circuit the
test leads/probes.
Step 2: Press and hold F3 (ZERO) button. The measured resistance of
the test leads is shown on the primary display until a beep is heard and
the ZERO annunciator appears. When Display shows 0.00Ω, test lead
resistance zero is complete.
The tester measures test leads / probe resistance, stores the reading in
memory, and subtracts it from readings. The resistance value of test leads
/ probe is saved even when the Tester is switched off. When the next time
you switch on the Tester, you do not need to repeat test lead / probe
zeroing step every time you use the Tester. When using a different set of
test leads / probes, zeroing has to be repeated.
Note: The ZERO function can subtract up to 10Ωof lead resistance.
Warning buzzer audio sound for lead resistance >10 Ω.
