Product Overview:
This instrument is used to measure the internal impedance and voltage of the battery. It applies a1KHz AC signal to the object to be measured and obtains its internal resistance by measuring its ACvoltage drop (it is different from the principle of measuring resistance with a multimeter, which measuresthe value at milliohm level, while the multimeter measures the resistance at ohm level, and themultimeter can only measure the resistance of objects without power supply, while the internalresistance meter can measure the resistance of both passive objects and active objects), It judges thequality of the battery by measuring the internal resistance. Not only the testing speed is fast, but also thereliability is high. Its greatest advantage is that it can set the range of test parameters, the measuredresults are not within the set range, and the microcomputer system can automatically alarm. To preventhuman misjudgment and misreading and ensure product quality.
