"SUN CAL": Configuring the brightness threshold for sunshine duration
The WS888 weather station measures the sunshine duration with its combination sensor. The threshold value is set
at the display console and is then transmitted to the combination sensor. The sensor then evaluates the data:
Measured brightness greater than threshold
¨
sun is shining
Measured brightness smaller than threshold
¨
sun is not shining
The brightness threshold can be set individually by the user to adjust the sensor to the local conditions. The threshold
value should be defined when the sun begins or stops to shine to make conclusions from the present brightness value
to the threshold.
• Select the "SYSTEM" menu and here (via "BEEP", "DCF", "DST", "INTERVAL", "ALTITUDE" and "RAIN CAL")
the option "SUN CAL":
SUN CAL ENTER
SUN CAL ENTER
SUN CAL ENTER
SUN CAL ENTER
SUN CAL ENTER
• Touch "ENTER" and you will see:
SUN CAL 131 + 085 -
SUN CAL 131 + 085 -
SUN CAL 131 + 085 -
SUN CAL 131 + 085 -
SUN CAL 131 + 085 -
The medium display range (131 in the above example) shows the present brightness value.
The direct conversion into lux is not possible.
The right display area (085 in the above example) shows the adjusted threshold value.
• Touch "+" or "-" to set the threshold value. The setting range is from 0 to 255.
• Wait a few seconds until the station resumes normal mode.
