7.6.1 Reset Run Hours and Energy Count
To reset the run hours and/or energy count of a lamp actuator click on the
Reset Run

7.6.2 Calibrate Light Sensor
To calibrate the light sensor click on the
Calibrate Light Sensor …
button. The dialog
shown in Figure 156 is opened.
Figure 156: Light Sensor Calibration
To counter any non-linearity the sensor can be calibrated for up to seven different daylight
illumination levels. However, in most cases it is sufficient to calibrate the sensor only once.
The best result is achieved if the illumination level is near the setpoint. To calibrate the
sensor perform the following steps:
1.
Measure the current lux level at the reference area (e.g. desk) using a luxmeter.
2.
Enter the measured lux level in the input field
Measured Lux Level
.
