Description

technical field [0001] The invention relates to a calibration device for a storage battery charging and discharging detector. Background technique [0002] The battery charge and discharge detector not only needs to measure the test parameters, but also needs to control the battery charge and discharge, so it is not only a testing instrument, but also a control device. Before the detector leaves the factory, the manufacturer of the detector must perform two parts of work: the calibration of the measured value (voltage and current measured value) and the calibration of the control value (constant current output and constant voltage output) of the instrument. [0003] At present, the calibration of the battery tester is manually calibrated by the operator for each parameter. When the measured value is calibrated (such as voltage and current calibration), high-precision voltage and ammeter must be used to observe the value displayed by the detector and the value displayed by t...
