Tracking File

The tracking file contains the temporal voltage and current data of the tracking phase of the measurement.

The columns are the following:

  • Time (Hours)
  • Voltage (V)
  • Current Density (mA/cm²)
  • Power (mW/cm²)

In addition, if an environment is configured (see environments), an additional column is added after the power column for each sensor.
