TopDiag P60 Automotive Circuit Tester Diagnostic Diode Detector

P60 Automotive Electrical Circuit Tester, Component activation, Voltage detection, Diode detection, Continuity testing, Ground detection, Tracing and locating short circuits, Positive and negative pole detection. P60 Automotive Circuit Tester Feature: 1.Voltage and positive and negative detection: When the device is connected to the car's power supply, the display lights up white and the screen will show 0v. When the probe is touched to the positive circuit, the screen will show the current circuit voltage. (If the device power supply and the circuit being tested are separate, then the ground lead of the device needs to be connected to the negative terminal of the circuit being tested). If the probe touches the negative circuit, the display will light up green, the screen will show 0v, and the device will sound a beep.2. Diode detection: Connect the ground lead to the negative terminal of the diode and the probe to the positive terminal of the secondary tube, when the icon appears on
