Introduction to the internal resistance of lithium batteries measured by multimeter
1. Electricity measurement: Electricity measurement is mainly to measure the quality of its charge and discharge, adjust to the ohm gear, and then use two test leads to connect its two feet respectively. At this time, the number on the meter will gradually increase, and finally become Infinity, and then change the pen, the situation is the same as before.
2. Measuring resistance: Measuring resistance is mainly to measure whether the resistance value is accurate, adjust to the ohm range, connect its two legs with a test pen, and check whether the reading of the multimeter is the same as the actual resistance value of the resistance.
3. Inductance measuring coil: The inductance measuring coil is mainly used to test whether it is conductive, and it is also in the ohm range. Just connect its two legs with a test pen. The inductance is simply a wire, and its resistance should be very small.
4. Transformer measurement: There are many similarities between transformer measurement and inductance measurement.
