[0002] When battery testing equipment calibrates or adjusts channel voltage / current, it requires a current or voltage source for input and output. The traditional approach involves using calibration tooling in conjunction with calibration software to automatically calibrate during calibration or adjustment. However, some battery testing equipment operates at high currents and supports input / output as a voltage or current source. Developing high-current calibration tooling, as is traditionally done, would be prohibitively expensive and hinder marketability.
