Vehicle Wiring Electrical System Tester

AUTOOL BT250 electric circuit tester 6Volts - 30Volts AUTOOL BT250 electric circuit tester is suitable for diagnostic in all 6V to 30V vehicle electrical systems. With a simple hook-up of the tool to the vehicle's battery, AC voltage detection, DC voltage detection, Resistance Detection, Diode Test, Current overload protection 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 1.5m ]: Covering from the front to the rear of the vehicle, you can easily inspect the entire electrical circuit system.
