Type SCCAL
The SkyVUE 8 will respond:
Stratocumulus calibration.
Enter height above sea level (m)? Press enter to continue:
Enter the sensor height above sea level, for example 70 m then type return.
The SkyVUE 8 will respond: 70 m entered, is this correct? “Y”, “N” or “Q”
Type
Y
to confirm. If you have entered an incorrect number, type
N
and you will be able to
replace it. Type
Q
to quit the calibration and return to the terminal command prompt.
The SkyVUE 8 will respond:
For correct calibration a trained human observer must confirm that the layer is between 250 m
(820 ft) to 2500 m (8200 ft) and has been stable for at least 10 minutes without drizzle. Has the
Stratocumulus been stable for at least 10 minutes? “Y” or “N”
To confirm, type Y and the SkyVUE 8 will respond:
Old Stratocumulus calibration = 0.0282
New Stratocumulus calibration parameters = 0.0258 70 1328
Do you want to apply this calibration? “Y” or “N”
In this example, 70 is the height of the sensor above sea level previously entered and 1210 is the
cloud base in met
re
s above the sensor.
As a rough guide, if the calibration factor has changed by less than 20%, there is no need to
change. If it has changed by a factor of 2, it is wise to run the service routine on the sensor (see
Service command (p. 58)).
Type Y to confirm and the SkyVUE 8 will respond:
Calibration saved.
The following error messages may appear during the process.
l
Error ... Time out
l
Error ... Cloud not detected or height not within limits
(250 m to 2500 m / 820 ft to 8200 ft)
l
Try again when layer is stable
l
Error ... Not enough data available try again in 10 minutes.
