Detect the battery charge status, the test results are divided into four categories (full, normal, need recharging, completely empty), suitable for10AH--200AHBattery. The circuit of the tester does not require the separation of the positive and negative poles. The surface of the battery tester clearly indicates the open-circuit voltage of the battery being tested, along with the detection switch used during the test, which makes operation convenient. Connect the tester to the battery to be tested, and the voltmeter shows the voltage value of the battery. The nominal normal voltage of the battery is between 12.5v--13v。 Turn on the test switch, and the pointer will drop, indicating the state of the battery: normal, heavy charge, or completely discharged.12vThe generator can be used for direct testing of electricity generation.
Usage Method
1. Clamp the test instrument's clamps to the positive and negative poles of the battery, and the indicator light will turn on (the clamp end with the light is the battery's positive pole). The voltmeter will indicate the battery voltage, which is a false voltage (no-load voltage) at this time.
2If the light does not work or the voltage meter needle does not move, check whether the test instrument clamps are in good contact with the battery terminals.
3Turn the knob switch, the time shall not exceed5秒（此时测试仪以100ADischarge the battery, and the needle of the voltmeter will shift to the left. Based on the position of the shift, you can judge the battery's charge condition. The test results can be roughly divided into the following five situations:
1.The pointer is in the green zone, indicating that the battery is fully charged.
2.The pointer is in the yellow zone and the pointer is stable, indicating that the battery is low and needs charging.
3.The pointer falls quickly to the left, indicating that the battery no longer has power.
4.The pointer returns to zero, indicating that the battery may have a broken cell.
5.The pointer in the red zone indicates that the battery power is very low, and the battery may have defects.
