Accurate and rapid measurement of various battery parameters during production is a key link in the battery production process and a necessary means of battery quality control.

[0003] In the process of measuring OCV and ACIR, the common practice is to use a high-precision digital multimeter and a battery tester to measure the OCV and ACIR of the battery. The instrument needs to be zeroed before measurement. When zeroing, the input signals of the instrument probes need to be short-circuited. When using automated equipment for testing, the input leads of each instrument are connected to the measurement channel. If the input signals need to be short-circuited manually during zeroing, the operation is extremely inconvenient. A test fixture suitable for automated equipment that can quickly adjust to zero is needed. Utility Model Content
