Features:Suitable range: suitable for cars, trucks, trucks, motorcycles.Internal application load switch - does not triggerSuitable for 6V and 12V batteriesAccurately display the voltage of the batteryTips:1. During the test, the surrounding should be well ventilated.2. Clean the battery after the measurement is over.3. Check the battery for broken parts or damage.4. If it is necessary to pull the battery out of the car, please remove the grounding battery first, and take out other accessories carefully to avoid electric shock.Introduction to use:1. Clip the two clips of the tester to the positive and negative poles of the battery. At this time, the indicator light is on (the end of the clip on the side of the lamp is the positive pole of the battery), and the voltmeter indicates the voltage of the battery. At this time, it is a virtual voltage (no-load voltage).2. If the lamp does not light or the voltmeter pointer does not move, check if the tester clip is in good contact with the battery pole.3. Twist the toggle switch for no more than 5 seconds. When the rated capacity of the battery is 20-500A, the discharge current is 100-120. (At this time, the tester discharges the battery with 100A), the pointer of the voltmeter is shifted to the left, according to The offset position determines the battery status of the battery.A. The pointer indicates sufficient power in the green zone.B. The pointer is in the yellow zone and the pointer is stable indicating that the battery is low and needs to be charged.C. The pointer falls back to the left, indicating that the battery has no power.D. The pointer returns to zero, indicating that the battery may be broken.E. The pointer indicates that the battery is very low in the red zone and the battery may be defective.Item Type:Battery TestersModel Name:T16594Voltage:6/12VItem Length:28Item Width:16Item Height:6Item Weight:1.08Material Type:PlasticElectronic:Noincludes:1x Battery Load Tester
