An overview,
Intelligent resistance tester is used to measure the battery internal impedance and battery acid membrane damage degree of instrument, hereinafter referred to as the instrument. It is the object to be measured 1 KHZ ac signal, ac by measuring the pressure drop and the internal resistance. (it is different from the principle of the multimeter to measure resistance, it is by measuring the value of the milliohm level, and the value of multimeter measurement is the ohm level; and multi-purpose table can only be measured object value, no power supply and internal resistance tester can not only test object value, no power supply is also measurable has a power resistance of an object, so both can not equal) using the resistance value to determine the size of the battery state of degradation, (in general) the resistance is smaller, the better the performance of battery. Therefore, adopting the method for measuring the battery internal resistance is high speed and reliability of a kind of good method.
Intelligent resistance tester is the biggest advantage is that can be set by the scope of the test parameters are not measured after the scope of the microcomputer system can automatically alarm, put an end to misjudgment misreading of human error, ensure the quality of products.
