Short press "enter key " to turn on. 2. Long press "enter key " to shut down. 3. Press the "set key" to enter the setting state, then press the "select key" to select different functions, and then press the "enter key" to enter the corresponding function. 4. Enter the resistance calibration/voltage calibration state. At this time, the test line should clamp the calibration resistance or voltage, press the "set key" to select the gear to be calibrated, and then press "+" and "-" to adjust the displayed value to be equal to the calibration resistance or voltage , Press the "select key" to select "ok" or "Cancel", and finally press the "enter key " to decide whether to save or cancel. As can be seen from the table below, the larger the battery capacity, the smaller the internal resistance. It is generally believed that if the internal resistance of the battery is greater than 1.25 times of the factory standard, it indicates that the battery has been severely aged and needs to be replaced in time. Actual Use Case Sampling resistance PC Software Interface Frequently Asked Questions 1. Zero adjustment problem, the clip short circuit is not zero? Answer: The short circuit of the two clips is not zero and there is x.xxxm, which is a normal phenomenon. Only when the two clips are in perfect contact will the minimum value (it may be 0 or very close to 0). It does not matter if it is not 0. During the measurement process, the internal program has calculated the theoretical zero point, which does not affect the accuracy and does not need to be calibrated to zero. 2.Does the battery need to be fully charged for measurement? Answer: The battery's full and depleted state will not affect the battery's internal resistance, and can be measured, with minimal changes in internal resistance (except for defective batteries). 3.The measurement result is jittery, inaccurate, unstable? Answer: The test result is unstable. It may be that the test clip is in poor contact with the battery, or the battery under test is unstable, the electrode has an oxide layer, or there is a strong magnetic field around it. 4.The measured internal resistance is greater than the battery internal resistance? Answer: When measuring large-capacity batteries (the internal resistance is very small), you must pay attention to the position of the clip during the measurement. The internal resistance of the battery electrode or connecting wire is often greater than the internal resistance of the battery itself. Pay attention to the position of the clip and make good contact. 5. Is it possible to measure xxxx batteries? Answer: The instrument can measure any type of batteries, including lithium batteries, lead-acid batteries, nickel-chromium batteries, dry batteries and so on. 6.Why can the internal resistance be measured to judge whether the battery is good or bad? Answer: The same battery will gradually wear out during use, the capacity becomes smaller and smaller, and the internal resistance becomes larger and larger. The smaller the internal resistance of the same battery, the stronger the load capacity, otherwise it will heat up or fail to move. The better the performance of the battery, the slower the aging, the worse the quality of the battery, the faster the aging. 7. What is the general internal resistance of an 18650 lithium battery? Answer: The internal resistance of the new 18650 lithium battery is generally below 50 milliohms, the better is about 20 milliohms, the general is about 30 milliohms, and the worse is above 50 milliohms. 8.How much battery capacity can be measured? Answer: You can measure batteries of any capacity, no matter how big it is, as long as the internal resistance is within 0-200 milliohms and the voltage is within 100V. 9. Can the internal resistance be measured online, and can the UPS power supply be tested? Answer: It can be tested online without affecting the working of the battery, so the battery can be tested continuously during UPS maintenance.
