Power tuning can be used to adjust the incident light level that is
currently being received to the power tuning target value (default: 2,000).

The power tuning target value can be changed. Refer to Detailed Settings.
The incident light level may change when the detection method is changed.
If necessary, retune the power after changing the detection method.
