Measuring principle of lithium battery insulation resistance tester:
Lithium battery insulation resistance tester is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment. Its a kind of insulation resistance test set. The rated output test voltage range is 250～5000V, and the insulation resistance measurement range is 0.01MΩ～5.00TΩ. The measuring range of DC voltage is 0～1000V, and the measuring range of AC voltage is 0～750V.
Insulation resistance measurement uses a voltage generator to generate a voltage V, which is applied to both ends of the resistance, by measuring the current I flowing at both ends of the resistance, and calculating the grounding resistance value R according to the formula R=V/I.
Please note the measurement principle of the lithium battery insulation resistance tester: insulation resistance measurement can only be carried out on uncharged circuits. Before measurement, please check whether the test circuit wire is intact and whether the circuit under test is charged. The charging of the circuit may damage the meter and affect the measurement. Accuracy.
