Battery Tester. KM05 12/24V Car Circuit Tester Digital AC/DC Voltage Power Circuit Probe Kit Battery Tester Electrical Diagnostic Tool

1. Voltage and polarity testWhen the instrument is in DC voltage mode,1) If the probe contacts the positive electrode circuit, the red LED light will light up, and the display will display a voltage with a resolution of 0.1V.The beep will sound.2) If the probe contacts the negative electrode circuit, the green LED light will light up, and the display will display a voltage with a resolution of 0.1V.The beep will sound.3) If the probe contact is open, neither of the two LED lights will light up.2. On-off testWhen the instrument is in resistance mode, a probe (chassis grounding) or auxiliary grounding wire can be used to test the lines connected or disconnected from the vehicle.Or the on-off properties of the components.When the probe is well grounded, the display will display "0.0", the green LED will light up, and a beep will sound.3. Signal Circuit TestingOnce you extract a DTC from the vehicle and realize that troubleshooting begins with some kind of sensor circuit, there is a quick test you can perform to verify the code. Testing your sensor is easy while using the tool.4. Manually activate the elementThe steps to activate the bulb are as follows:Press the power switch forward to activate the light bulb.the probe contacts the positive terminal of the light bulb.Connect the negative electrode auxiliary clip.SpecificationsDisplay: TFT color display (160*128dpi)Operating Temperature: 0 to 60 (32 to 140)External Power: 12 or 24V DC power provided via vehicle batteryDC voltage range: 0-65V +1digitResistance range: 0-100 kFrequency response of tone pass through 0Hz to 10Khz.Circuit BreakerRating current: 1-10 AmpTesting Standard:100% current: Hold > 1 hour150% current: trip in one hour200% current: trip in 3-30 seconds.300% current: trip in 0.5-4.0 seconds.Package list1 × KM10 Main Unit1 × 13ft.
