Specification:
Item Type: Circuit Tester
Material: Plastic + Metal
Operation Voltage: 6-24V DC
Cable Length: Approx. 4m/4.4yd
Overload Protection: 10A (When the current exceeds 10A, this item will disconnect the current automatically.)
Wiring: Red to Positive, Black to Negative
Applications:
- Test for continuity
- Test for polarity of a voltage
- Check switches, relays and the on-off of diodes, fuses and circuits
- Test for polarity of electric cables and plugs
- Track and locate short circuits
- Test for bad ground contacts
Do's and Don'ts:
- Do not use the item around explosive gas, vapor, or dust. When the power switch is pressed (or rocked), battery current is conducted directly to the tip which may cause sparks when contacting ground or certain
- The unit is not to be used with 110/220V house current, it is only use for DC 6-24V systems.
- Do not use on AC voltage.
- After you finishing checking vehicle, correctly restored all the connection-s which you disconnected.
- Always follow the instructions and procedures indicated in the vehicle's service manual before attempting to disconnect any part or subsystem of the electrical circuit.
- Never touch any dangerous part of the vehicle with your hand for safety. Don't touch any live conductor with hand or skin.
- Don't use it if it is damaged.
- Some components of vehicle work on low voltage, they cannot withstand the voltage allied by the item. To avoid damage for these components, don't use the item to apply voltage directly or indirectly.
- Before driving, please always make sure that the vehicle is safe and reliable.
- Don't use this item when driving.
Features:
1This power probe can help you quickly identify the positive and negative polarity of cables and plugs. The red light indicates positive polarity, and the green light indicates negative polarity. 2You can also test the continuity with the help of the auxiliary ground wire. Check the continuity of switches, relays, diodes, fuses, spark plugs, and circuits. 3Fast track short circuit, when the fuse blows, it may be caused by a short circuit or a sudden increase in component load. The circuit tester can help you trace the problem cable and find the breakpoint. 4For some components that require a large current to flow through the negative terminal, the shortcircuit protection circuit tester can immediately test the bad ground contact and start lead. 5The test pen has an overload shutdown protection function. If the current or load is too large during power distribution, the test pen will automatically disconnect to protect the battery and issue a buzzer warning. 6The insulating material used in the electrical tester has passed the CCC national safety compulsory certification, which is safe and reliable. It is widely applicable to all 6-24VDC vehicle electrical systems. 7With a 4 meters long cable, you can easily test. This device is the best electrical tester to reduce the diagnostic time of automobile electrical systems.
