Time Needed for Low Temperature Test

After golden learning and accuracy test at room temperature, users also need to perform an accuracy test at low temperature. This includes test items below. These tests can take approximately 3-4 days.

  1. Charge at room temperature and discharge at low temperature.
  2. Discharge at room temperature and charge at low temperature.
  3. Charge at low temperature and discharge at low temperature.

If there is something wrong during the accuracy test at low temperature, then users need to run the Gauging Parameter Calculator (GPCRB). This optimizes room and low temperature performance Impedance Track gauges. This can also help to improve the low temperature performance.

For detailed instruction, users can refer to the Golden GG Maker and Resistance Temperature Compensation Optimizer application note.

After GPCRB, users need to also run room temperature and low temperature accuracy tests to verify if the performance gets improved. This can take approximately 4-5 days.
