5. Instrukcja obsługi
The THINKCAR ACT20 offers various testing modes for comprehensive electrical diagnostics.
5.1. AC/DC ObjętośćtagTest
This function allows you to measure both alternating current (AC) and direct current (DC) voltages in the vehicle's electrical system.
- Connect the ACT20 to the vehicle's power source as described in Section 4.
- Touch the precision probe to the circuit or component you wish to test.
- Na wyświetlaczu cyfrowym pojawi się zmierzona objętośćtage. The device automatically detects AC or DC voltage.
- Observe the polarity indicator on the screen for DC voltage odczyty.
5.2. Polarity Verification
Quickly determine the positive or negative polarity of a circuit.
- With the device powered on, touch the probe to the test point.
- The display will indicate whether the point is positive (+) or negative (-).
5.3. Test ciągłości
Use this function to check for open circuits or good connections.
- Przed wykonaniem testu ciągłości należy upewnić się, że obwód jest odłączony od napięcia.
- Connect the ACT20's ground lead to a known good ground point on the vehicle chassis.
- Touch the probe to one end of the circuit or component you want to test.
- If continuity exists, the device will emit an audible tone and/or display a specific indicator.
5.4. Short-Circuit Detection
Identify short circuits quickly and safely.
- Connect the ACT20 to the vehicle's power source.
- Carefully probe the suspected shorted circuit.
- The device will indicate a short circuit, often with an audible alarm or specific display message, and its internal protection will activate to prevent damage.
5.5. Aktywacja komponentów
Safely activate components directly from the device to test their functionality.
- Connect the ACT20 to the vehicle's power source.
- Connect the probe to the positive terminal of the component you wish to activate.
- Use the activation button on the device to supply power to the component. Observe the component's reaction.
- Ostrożność: Ensure the component's current draw does not exceed the device's maximum output to prevent damage.
6. Konserwacja
Proper maintenance ensures the longevity and accuracy of your THINKCAR ACT20.
- Czyszczenie: Wipe the device and cables with a soft, dry cloth after each use. Do not use abrasive cleaners or solvents.
