1. Detect Car Circuit Easily
The traditional multimeter cannot support live line measurement, which may burn out the multimeter. Test lead generally allows only 1.5 meters for 2-hands testing. Outage measurement may damage the car. You’ll have to know where the GND is if judging by voltage… Godiag GT103 can help to avoid all these trouble.
