Naudojimo instrukcijos

ttage ir poliškumo tikrinimas

Norėdami patikrinti ttage and polarity, contact the probe tip to the circuit point. The tool's display will show the voltage reading, and the LEDs will indicate polarity:

• A RAUDONA LED indicates positive voltage.
• A ŽALIA LED indicates negative voltage (ground).

Vaizdo aprašymas: The allsun GMEM287 circuit tester held in a hand, with its display showing operation voltage, DC ttage range, and overload protection specifications. The probe tip is visible.

Tęstinumo testavimas

Connect the auxiliary ground lead to a known good ground. Touch the probe tip to the component or wire you wish to test. If the circuit is continuous, the green LED will light and a beep tone will sound.

Short Circuit Tracing

The tool's long cable allows you to follow and locate short circuits along the entire length of the vehicle without constantly searching for suitable vehicle grounds. The audible tone and LED indicators will guide you to the fault location.

Komponento aktyvinimas

By depressing the power switch (rocker switch) forward or backward, you can conduct a positive or negative battery current to the probe tip for testing the function of an electrical component without the use of jumper wires. This is useful for activating components like fuel pumps, starter solenoids, magnetic clutches, blower motors, cooling fans, and lights.

Žemės bandymas

Nedelsdami patikrinkite, ar nėra prastų įžeminimo kontaktų, neatlikdami tūriotage drop tests. The green LED will indicate a good ground connection.

Apšvietimo funkcija

The tool features a built-in flashlight to illuminate the test area, enabling automotive technicians to work in dark environments.

Priežiūra

Valymas

Keep the tool dry, clean, and free from oil, water, or grease. Use a mild detergent on a clean cloth to clean the outside of the tool when necessary.

Apsauga nuo perkrovos

The tool is short-circuit protected. Its internal circuit breaker will trip if it becomes overloaded (current exceeds 8A). This protects the tool from damage. If the circuit breaker trips, allow it to cool before resuming use.

Trikčių šalinimas

• Nėra galios: Įsitikinkite, kad akumuliatorius yra klamps are securely connected to the correct terminals of the vehicle battery. Check for corrosion on battery terminals.
• Neteisingi skaitymai: Verify that the probe tip is making good contact with the circuit. Ensure the tool is in the correct operating mode for the test being performed.
• Circuit Breaker Trips: If the internal circuit breaker trips, it indicates an overload. Disconnect the probe from the circuit, allow the tool to cool, and check the circuit for shorts or excessive current draw before retesting.
• No Audible Tone/LED Indication: Check battery connections. Ensure the tool is functioning correctly by performing a quick self-test on a known good circuit.
