5. Tatūnga

5.1. Tāuta Pūhiko

The Testo 750-2 requires 2 AAA batteries for operation. These are typically included.

1. Locate the battery compartment cover on the rear of the tester.
2. Use a suitable tool (e.g., a small screwdriver) to open the compartment.
3. Whakauruhia kia toru ngā pākahiko AAA, me te tirotiro i te polarity tika (+/-) e whakaaturia ana i roto i te wāhanga.
4. Me tino kati te taupoki o te waahanga o te papahiko.

The device will perform a self-test upon battery installation or when first used, indicated by all LEDs briefly illuminating.

6. Nga Tohutohu Whakahaere

6.1. Rererangitage Testing (AC/DC)

Hei ine voltage:

1. Me whakarite kia ma te taputapu whakamātautau, kia kore hoki he pakaru.
2. Connect the L1 and L2 test probes to the points where voltage me ine.
3. The LED display will illuminate to indicate the detected voltage level (e.g., 12V, 24V, 50V, 120V, 230V, 400V, 690V).
4. Mo DC voltage, the polarity will also be indicated (+/-).
5. An audible signal will sound when voltagka kitea e.

Note: The Testo 750-2 is designed to provide a clear indication of voltage presence even with discharged batteries, ensuring safety.

6.2. Whakamatau Tonu

To test for continuity (low resistance):

1. Ensure the circuit or component is de-energized before testing for continuity.
2. Connect the L1 and L2 test probes across the circuit or component.
3. If continuity is detected (resistance below a certain threshold), the "Rx" LED will illuminate, and an audible signal will sound.

6.3. Phase Rotation Testing

To determine phase rotation in three-phase systems:

1. Connect the L1 probe to the first phase (e.g., L1).
2. Connect the L2 probe to the second phase (e.g., L2).
3. The "L" or "R" LED will illuminate to indicate the direction of the rotating magnetic field (left or right).
4. For a complete three-phase test, connect the L1 probe to L1, L2 probe to L2, then L1 probe to L2, L2 probe to L3, and finally L1 probe to L3, L2 probe to L1, observing the sequence.

6.4. GFCI Trip Test

To test Ground Fault Circuit Interrupter (GFCI) functionality:

1. Connect the L1 and L2 test probes to the live and ground terminals of the GFCI-protected outlet or circuit.
2. Press and hold the GFCI test button on the tester.
3. The GFCI device should trip, interrupting power to the outlet/circuit.
4. Release the button and reset the GFCI device.

CAUTION: This test will temporarily cut power to the circuit. Ensure no critical equipment is connected or that appropriate precautions are taken.

6.5. Ko te rama rama-i roto

To activate the flashlight, press the flashlight button located on one of the tester units. Press again to turn it off. This feature is useful for illuminating dark work areas.

7. Tiaki

7.1. Te horoi

Clean the tester regularly with a damp kakahu. Kaua e whakamahia he kaihoroi whakakoi, he wairewa rānei. Me whakarite kia maroke te taputapu i mua i te rokiroki, i te whakamahinga rānei e whai ake nei.

7.2. Whakakapinga Pūhiko

When the battery low indicator appears (if applicable) or the device's performance degrades, replace the batteries as described in Section 5.1. Always use new AAA batteries of the same type.

7.3. Rokiroki

Store the tester in a dry, clean environment, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.

8. Te Raru

• No Indication / Device Not Turning On:
  • Check battery installation and polarity.
  • Whakakapihia nga pākahiko ki nga mea hou.
  • Ensure probes are making good contact with the test points.
• Panui Tauriterite:
  • Verify the tester on a known live source.
  • Check for damaged test leads or probes.
  • Ensure proper contact with the circuit.
• GFCI Test Not Tripping:
  • Ensure the GFCI outlet/circuit is properly wired and functional.
  • Confirm the tester is connected correctly (live to ground).
  • If the GFCI still does not trip, the GFCI device itself may be faulty and requires inspection by a qualified electrician.

If problems persist, contact Testo customer support.
