APPENDIX D
CALIBRATING THE TS SENSOR
This appendix describes how to calibrate the TS sensor.
Vaisala recommends checking the TS sensor accuracy once a year. If the
TS value differs more than 2.5 °C from the ambient temperature, it is
recommended that you calibrate and adjust the sensor.
For optimal results, perform the checking, calibration, and adjustment
procedure at the PWD site on a cloudy day when the ambient
temperature is close to 0 °C (0 … +10 °C).
The checking and calibration is carried out with the TS sensor removed
from the cross arm to avoid the possible heating effects by electronics or
hood heaters.
The known ambient temperature is gained from a calibrated reference
sensor, such as Vaisala HMT330TS.
