6. Mode d'emploi
The GT101 is designed for use on DC 6-40V vehicle electrical systems, including cars, motorcycles, trucks, buses, construction vehicles, ships, and tractors.
Vol 6.1tage and Polarity Testing
Touch the probe tip to the circuit or component to be tested. The digital display will show the voltage, and the LED indicator lights will indicate polarity:
- Voyant rouge : Indicates a positive (+) circuit. A short, quick buzzer sound will accompany this.
- Voyant vert : Indicates a negative (-) circuit. A gentle buzzer sound will accompany this.

6.2 Essai de continuité
To perform a continuity test, 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 tester will indicate continuity (e.g., a specific light or sound, refer to device display for exact indication).
6.3 Test du circuit de signal
Connect the probe to the signal wire. The tester will display the signal voltage, allowing for diagnosis of signal integrity.
6.4 Essai actuel
The GT101 can measure current. Refer to the device's display for current readings. Ensure the circuit does not exceed the 20A limit of the built-in circuit breaker.
6.5 Circuit Breaker Protection
The tool features a built-in 10 amp circuit breaker. If the current drawn during testing exceeds 20A, the breaker will automatically trip to protect the equipment and the vehicle's electrical system. Reset the breaker before continuing operations.
6.6 Test de relais
Use the provided Simple Relay Test Adapter and Connection Leads to test automotive relays. Connect the adapter to the relay and the GT101. The tester can activate the relay and check its operational status.
6.7 Injector Test and Cleaning
The GT101 includes a DIY injector cleaning adapter kit.
- Test de l'injecteur : Connect the fuel injector to the GT101 using the appropriate adapter. The tester can drive the injector to open and close. Observe the current display; a normal value indicates a functional injector. Abnormal readings suggest damage.
- Nettoyage des injecteurs : If an injector is clogged, connect it to the GT101 and a pressurized cleaning tank (not included). The GT101 can activate the injector to facilitate cleaning.

6.8 Component Activation and Testing
The GT101 can supply power to electrical components for activation and testing. This allows for verification of component function without needing to fully reassemble the circuit. Use caution to avoid over-powering components.
6.9 Poor Ground Testing
By applying a known good ground or positive voltage, the GT101 can help identify poor ground connections in a circuit.
6.10 Tracking and Locating Shorts
The GT101 can assist in tracing and locating short circuits by providing power and monitoring current draw, helping to isolate the fault area.
