Checking TS Sensor Temperature
PWD can compute the offset at any temperature of Tref, but Vaisala
recommends a temperature close to 0 °C because it is used to identify
freezing rain.
To check the TS sensor temperature:
1. Connect to PWD using a laptop computer and a terminal program.
2. Depending on whether your PWD has an internal or an external
temperature sensor, perform either a. or b.
a. If your PWD has an internal temperature sensor:
Use a 2.5 mm Allen key to open the small cable cover under the
receiver housing, remove the cover plate, and pull the light grey
4 mm thick TS sensor cable out of the tube. Make sure you do not
pull the other end of the cable that comes through the rubber gasket
as that would degrade the watertightness of the enclosure.
