An introduction to measuring lithium battery internal resistance with a multimeter
1. Electricity measurement: The main goal of electricity measurement is to evaluate the charge and discharge of an electrical system, set the ohm gear appropriately, and then use two test leads to connect each of the system's two feet. When the pen is switched, the situation is the same as it was before. At this point, the number on the meter will progressively rise until it reaches Infinity.
2. Measuring resistance: The major goals of measuring resistance are to check the accuracy of the resistance value, set it to the ohm gear, connect its two feet to a test pen, and determine whether the reading from the multimeter matches the resistance value in question.
3. Inductance measurement coil: The inductance measurement coil, which is likewise in the ohm range, is mostly used to evaluate whether something is conductive. Just use a test pen to join its two legs. Simply a wire, the inductance should have a very low resistance value.
4. Measuring a transformer: Measuring a transformer and measuring an inductance have a lot in common.
