1. Outstanding Features
The positive measurement digits show the voltage value, allowing accurate result reading. When it is removed, the value is delayed by about 3 seconds, convenient for recording results. The negative pole measurement no voltage value showing, but the green LED lights up, and the beeper ringing. Measuring range 0.3 ~ 60VDC, suitable for many automotive electrical systems. Can be tested without battery vehicle, test with ground contact aid. With 100CM double clamp ground contact wire, flexible during operation.
2. Practical Applications
Testing positive voltage on automotive electrical systems with digital display. Identifying negative pole via green LED and beeper sound. Testing vehicles without battery thanks to ground contact aid. Supporting circuit fault diagnosis on passenger cars and light trucks. Checking voltage signals in electronic control systems. Used in garages, service workshops and technician training. Suitable for quick checks when installing auxiliary electrical equipment.
3. How to Use
Step 1: Connect the 100CM double clamp ground contact wire to the device.
Step 2: Clamp the ground end to earth point or vehicle frame.
Step 3: Touch the probe to the point to be tested on the circuit.
Step 4: Observe the digital display to read the positive voltage value.
Step 5: Record the value within the 3 second delay after removing the probe.
Step 6: Check negative pole via green LED and beeper sound.
Step 7: Disconnect and store the device after testing is complete.
4. Device Maintenance
Clean device body and probe with soft damp cloth after each use. Do not immerse device in water or strong solvents. Check the 100CM double clamp ground contact wire periodically for breakage or cracks. Check green LED and beeper periodically. Replace battery when display is weak or does not turn on. Store in dry place, avoid direct sunlight and high temperature. Do not use device outside 0.3 ~ 60VDC measurement range. Store in carrying case when not in use.
