4. Ρύθμιση

1. Συνδέστε το κλιπ Alligator: Securely attach the alligator clip to a known good ground point on the vehicle chassis or the negative terminal of the battery. Ensure a clean, solid connection for accurate readings.
2. Prepare the Probe: Remove the protective cover from the stainless steel probe tip.

5. Οδηγίες λειτουργίας

5.1. Τομtage Δοκιμή

1. Ensure the alligator clip is securely grounded.
2. Carefully touch the probe tip to the circuit or component you wish to test.
3. Η ψηφιακή οθόνη θα εμφανίσει την έντασηtage reading. The LED indicator will illuminate (red for positive, green for negative) to indicate polarity.
4. Αν ο τόμtage exceeds the tester's maximum capacity (90V DC), the display may show an error or an "H" indicating high voltage. Disconnect immediately.

5.2. Δοκιμή συνέχειας

1. Ensure the circuit is de-energized before performing continuity tests.
2. Connect the alligator clip to one end of the component or wire to be tested.
3. Touch the probe tip to the other end.
4. If continuity exists, the LED indicator will light up (typically green for continuity, or red if connected to a positive source through the component) and the display may show a low resistance value or a specific continuity symbol.

5.3. Fuse Testing

1. With the circuit energized, connect the alligator clip to a known good ground.
2. Touch the probe tip to each test point on the top of the fuse.
3. If both sides of the fuse show a voltage reading, the fuse is good. If one side shows voltage and the other does not, the fuse is blown.
