Abstract
A clamp meter system with a battery-internal-resistance-measuring function includes a first processing unit, an analog-to-digital converting circuit, a current-measuring circuit, a direct-current current sensor, a voltage-attenuating network and a voltage probe set. The first processing unit uses the analog-to-digital converting circuit, the current-measuring circuit, the direct-current current sensor, the voltage-attenuating network and the voltage probe set to measure a battery current and a battery total voltage of a plurality of batteries to obtain a second digital current signal and a second digital voltage signal. A first digital voltage signal subtracts the second digital voltage signal to obtain a voltage difference. The second digital current signal subtracts a first digital current signal to obtain a current difference. The voltage difference is divided by the current difference to obtain an overall internal resistance value of the batteries.
