Functional features:
1. The main control chip adopts high-performance ARM, ensuring smooth and stable device operation
2. Using a 24 bit ADC for higher precision voltage and current testing than in the industry
3. The sequence of testing steps can be edited, and the testing parameters can be adjusted
4. The voltage and current are sampled using a four wire system, which has high voltage sampling accuracy and good long-term stability
5. Support battery barcode input, with traceable test data history
6. Hold multiple testing items: open circuit voltage, charging voltage, charging current, discharging voltage, discharging current, charging overcurrent protection, discharging overcurrent protection, short circuit testing, DC internal resistance, AC internal resistance, NTC and other items
