Asennus
Yhdistäminen ajoneuvon akkuun
The allsun GMEM287 is powered directly by the vehicle's battery. Follow these steps to connect the tool:
- Yhdistä PUNAINEN akku clamp kohtaan POSITIIVINEN ajoneuvon akun napa.
- Yhdistä MUSTA clamp kohtaan NEGATIIVINEN ajoneuvon akun napa.
- Once connected, the tool will power on, and the display will activate.

Käyttöohjeet
Voitage & napaisuuden testaus
Testaa voltage 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 PUNAINEN LED indicates positive voltage.
- A VIHREÄ LED indicates negative voltage (ground).
Kuvan kuvaus: The allsun GMEM287 circuit tester held in a hand, with its display showing operation voltage, DC voitage range, and overload protection specifications. The probe tip is visible.
Jatkuvuuden testaus
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.
Komponenttien aktivointi
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.
Maatestaus
Testaa huonot maadoituskontaktit välittömästi ilman voltage drop tests. The green LED will indicate a good ground connection.
Valaistustoiminto
The tool features a built-in flashlight to illuminate the test area, enabling automotive technicians to work in dark environments.

Huolto
Puhdistus
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.
Ylikuormitussuoja
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.
Vianetsintä
- Ei virtaa: Varmista, että akku on kiinniamps are securely connected to the correct terminals of the vehicle battery. Check for corrosion on battery terminals.
- Väärät lukemat: 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.
