MRCARTOOL B550 Car Electric Tester Features :

1.[AC & DC Voltage Detection Mode]: AC detects the maximum and minimum voltage, supply frequency and duty cycle of the circuit under test. While DC volt. detection detects the voltage value of the circuit under test.

2.[Resistance Test & Diode Test Mode]: It detects the resistance between the circuit probe under test and the auxiliary ground; While Diode Test can quickly test the operation of the diode assembly and determines if it is conducting.

3.[Ultra Extension Inspection Cable 10m ]: Covering from the front to the rear of the vehicle, you can easily inspect the entire electrical circuit system.
