Kľúčové komponenty:

• Test Probes (L1, L2): Na kontakt s elektrickými obvodmi.
• LED displej: Označuje objtage levels (AC/DC), continuity, and phase rotation.
• Tlačidlo baterky: Aktivuje vstavané svietidlo.
• Testovacie tlačidlo GFCI: Initiates a GFCI trip test.
• Priestor na batériu: Located on the rear of one unit.

5. Nastavenie

5.1. Inštalácia batérie

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. Vložte 2 batérie typu AAA a dodržte správnu polaritu (+/-) uvedenú vo vnútri priehradky.
4. Bezpečne zatvorte kryt priestoru pre batérie.

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

6. Návod na obsluhu

6.1. Zvtage Testing (AC/DC)

Na meranie objtage:

1. Uistite sa, že tester je čistý a nepoškodený.
2. Connect the L1 and L2 test probes to the points where voltage sa má merať.
3. The LED display will illuminate to indicate the detected voltage level (e.g., 12V, 24V, 50V, 120V, 230V, 400V, 690V).
4. Pre DC objtage, the polarity will also be indicated (+/-).
5. An audible signal will sound when voltage sa zistí.

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

6.2. Testovanie kontinuity

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. Vstavaná baterka

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. Údržba

7.1. Upratovanie

Clean the tester regularly with a damp handričkou. Nepoužívajte abrazívne čistiace prostriedky ani rozpúšťadlá. Pred uskladnením alebo ďalším použitím sa uistite, že je zariadenie suché.

7.2. Výmena batérie

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. Skladovanie

Tester skladujte v suchom a čistom prostredí, mimo dosahu priameho slnečného žiarenia a extrémnych teplôt. Ak ho skladujete dlhší čas, vyberte batérie, aby ste predišli vytečeniu.

8. Riešenie problémov

• No Indication / Device Not Turning On:
  • Skontrolujte inštaláciu a polaritu batérií.
  • Vymeňte batérie za nové.
  • Ensure probes are making good contact with the test points.
• Nekonzistentné čítania:
  • Verify the tester on a known live source.
  • Skontrolujte, či nie sú poškodené testovacie káble alebo sondy.
  • 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.
