The internal resistance tester uses the resistance value of the internal resistance to identify the deterioration of the battery. (Generally speaking) the smaller the resistance value, the better the performance of the battery. Therefore, the method of testing the internal resistance to expand the test battery is faster. A good method for fast and high stability. So today we mainly talk to you about the maintenance methods and precautions of the internal resistance tester?

maintainance

1. The internal resistance tester is a high-precision electronic measuring instrument. It is not allowed to modify the power supply circuit without permission to prevent damage.

2. The test pen cannot be connected to a working voltage higher than 50V DC, and cannot be connected to an AC voltage or an AC power supply.

3. It must not be used when the back cover of the instrument is not completely covered.

4. To replace the battery, it must be unfolded after taking out the test leads and turning off the AC power supply. Slowly press and push the battery cover slightly to remove the battery cover, and replace the battery according to the specifications specified in the detailed description.

Precautions

1. The user must strictly follow the actual operation of this manual, and cannot violate the regulations or rude actual operation.

2. Attention should be paid to waterproof, moisture-proof and fireproof during product storage.

3. The schematic diagram and detailed description in the manual may have slight differences with the entity, and the entity shall prevail.

4. Non-manufacturer maintenance personnel or authorized maintenance personnel cannot repair without permission!

5. If you disassemble and repair the machine without the permission of the manufacturer, the warranty period will not work!
