The process for the production PGU calibration sweep is the same as for the pre-production temperature calibration sweeps, but it only needs to be done at one temperature (typically room temperature) for each PGU being calibrated.

1. Select "Iterative Calibration" >> "Calibration" >> "Sweeps" from the menu on the left.
2. Set the PGU name.
3. Set the calibration temperature.
4. Select the connected light meter.

5. If using ND filters, the software can automatically correct for color offset introduced by the filter. Color correction data can be recorded during the first per PGU sweep and used in following sweeps.
6. Enter desired values for measurement delay, number of averaged measurements, min/max PWM values, and increment values. Default values are typically acceptable.
7. To start the sweep press the "Start Sweep" button.

8. As in the temperature sweeps, data from the per PGU sweep can be viewed in the "Sweep Summary" section.
9. Different PGU sweeps can be compared against each other.
