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.

• 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.

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

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.



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 Ω and 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 10Ω of lead resistance. Warning buzzer audio sound for lead resistance >10 Ω.

Measuring Loop Impedance



• The Tester is designed for measurement on single phase system only – AC

230V, 50Hz (operating voltage range: AC 230V +10%/-15%, 50Hz).

• Make sure the wiring is correct and the ground wire is reliably connected

earth. The tester displays symbols of “L-PE”, “L-N” and “N-PE” to indicate the correct wiring connections. Blinking of symbols “L-PE” or “L-N” or “N-PE” indicates incorrect wiring.

• Make sure the grounding of the socket-outlet is connected to Earth. The

symbol of “L-PE” and “N-PE” on the display means grounding wire is not connected to earth or not well-connected to earth.

• When measuring the loop impedance/prospective short-circuit current,

make sure line and neutral wires are connected correctly. Pay attention to the wiring symbols on display.

• Use Volts function to check the circuit voltage before the measurement.

• “HOT” symbol on screen indicates over-temperature. Allow time for the

Tester to cool down for next measurements.

• Use the NO TRIP function for loop measurements.

• An RCD with a nominal fault current of 15mA or above will trip.

To measure L-PE loop impedance NO TRIP mode:

1. Turn the rotary switch to NO TRIP position. L-PE symbol on the screen (upper-left corner) indicates L-PE loop impedance.

2. Use the red, green and black (L – PE – N) terminals for this test. You can use test leads or mains test cord when measuring loop impedance. Check the signs of wiring connection before proceeding test.

Measuring RCD Tripping Time



• The Tester is designed for measurement on single phase system only – AC 230V, 50Hz (operating voltage range: AC 230V +10%/-15%, 50Hz).

• Any test and measurement procedures in circuits equipped with residual current

devices should only be performed after having consulted the operator terminals (data processing systems, material processing, motors, etc.).

• Equipment, which is connected downstream of a residual current

protective device (RCD) may cause a considerable extension of the operating time. Examples of such equipment might be connected capacitors or running motors.

• The protective earth must be free of external voltage for the RCD test.

However if an extraneous voltage is present (>50V fault voltage), the

Tester indicates >50V Uf having been generated by the measurement. The measurement interruption caused by excess of Uf is only generated by the actual voltage present between the neutral conductor (N) and the protective earth (E).

• Time-delayed residual current devices trip at nominal residual current

within 130…500ms, for double nominal fault current within 60…200ms.

• Such RCDs are implemented as main residual current protection devices

(please refer to IEC 61008-1) and are marked with the symbol “ S ”.

• At a measuring circuit without probe, available voltages between PE and

earth can inﬂuence the measurement.

• Before using the N-conductor as probe check that all neutral points have

low ohm resistance to the main neutral line. A available voltage of the N conductor to the earth can inﬂuence the measurement.

• The measuring function uses the N-conductor as a probe. Check rst

the connection between the neutral point of the distribution system and earth before the test is started. A possible voltage between the N-conductor and earth may inﬂuence the measurements.

• Leakage currents in current circuits following the RC circuit breaker may

have an inﬂuence on the test as well as a voltage between protective conductor or neutral conductor and ground.

• Attached loads or operating supplies which contains capacitors or

circulating machines can elongate the trip time.

• Measurements may be inuenced by potential elds of other grounding

systems.

• Measurements must be carried out in compliance with the respectively

valid standards and regulations.

• Make sure the wiring is correct and the ground wire is reliably connected

Connecting to the circuit

Correct wiring: “L-PE” and“L-N” symbols are displayed – proceed to test

Incorrect wiring: when wiring symbols are blinking on display – STOP! Check the wiring connections.

MAINTENANCE AND REPAIR

If the Tester fails to operate, check battery, test leads, etc., and replace as necessary. Double check the followings:

1. Check the battery. Replace the battery immediately when the symbol ” appears on the display.

“

2. Review the operating instructions for possible mistakes in operating

procedure.

Except for the replacement of the battery, repair of the Tester should be performed only by an Authorized Service Center or by other qualiﬁed instrument service personnel.

The front panel and case can be cleaned with a mild solution of detergent and water.

Apply sparingly with a soft cloth and allow to dry completely before using. Do not use aromatic hydrocarbons, Gasoline or chlorinated solvents for cleaning.

BATTERY AND FUSE REPLACEMENT

WARNING

To avoid shock, injury, or damage to the Tester, disconnect test leads/test cord before opening case.

Replacing BATTERY follow below steps:

1. Disconnect the test lead probe from measuring circuit.

2. Turn the rotary switch to OFF position.

3. Remove the screws from the battery cover and open the battery cover

4. Remove the batteries and replace with 8 x 1.5V Alkaline Batteries (AA or equivalent). Pay attention to the polarity signs.

5. Put the battery cover back and re-fasten the screw.
