Check the listing for details. Auto Diagnostic Multimeter Oscillometric AC/DC Voltage Current Circuit Tester. Condition: New. Listed at 129.00 USD. 12 TEST FUCTION - DC/AC Voltage Measurement, DC/AC Current Measurement, Resistance Measurement, Frequency Measurement, Diode Test, Oscilloscope Test, Automotive Circuit Test, Cranking Test, Injector Test, Relay Test, Analog Signal Test, Ignition Signal Test, K/CAN Line Data. The Multimeter Mode: The multimeter mode can measure the AC / DC voltage and current, resistance, diode forward voltage drop, on-off and frequency. Oscilloscope Mode: Oscilloscope mode is a complete itelligent measurement system，which includes signal input, data sampling, data processing and automatic search, with the waveform test bandwidth of 500KHZ. With a variable sampling frequency, the slowly varying signal amount can be measured. It is applicable to measuring and observing various signals on the automobile circuit during the car overhaul, including the motor drive signal and motor power voltage of new energy vehicle, fuel car engine ignition pulse signal, camshaft signal, crankshaft signal, wheel speed sensor signal, oxygen sensor signal and so on. Car Circuit Detection: Car circuit detection can online test the low voltage circuit, prompt high voltage or line leakage and output the power supply voltage. It can also output the power voltage to test the parts of the car, or lower the voltage to drive the parts of the car, such as lights; Test the battery voltage when the oil-fueled vehicle starts, and judge whether the vehicle starting system and the battery are in good condition; The Analog Signal Output: The analog signal output can be applied to the car ECU detection and can simulate the square wave and sine wave output and simulate the fuel injection signal to drive the fuel injection nozzle; Check the data signal K line and CAN bus signal in the vehicle.
