Technical specification
Using battery internal resistance meter
The device is used to measure the internal resistance of batteries and voltages of a maximum of 100 V and only direct current. The device can also measure the resistance of resistors in the circuit and other components. In this case, make sure that such a circuit is not under load. Failure to follow these instructions may result in irreversible damage to the device.
