Preparing the Sounding
Follow these steps to prepare the sounding:
1.
Start a new sounding with the sounding system. The sounding
system goes through reconditioning, frequency tuning, and timer
setting. For detailed instructions, see the relevant sounding system
manuals.
2.
When prompted, connect the radiosonde cable to the GC25/
radiosonde cable interface in the radiosonde. Text "UP" on the
connector faces upwards.
3.
When the sounding system is finished, the message "Ready for
sonde release!" appears on the display. Disconnect the radiosonde
cable.
4.
Set the sensor boom into flight position; Back of the radiosonde
facing you, press the sensor boom gently forward with your thumbs
until the plastic clips on both sides of the sensor boom click (you
may have to spread the plastic clips slightly) and the sensor boom
sits firmly in the bent position.
NOTE
Radiosonde RS92-D is typically operated with the radiosonde cable or
by reading the calibration coefficients via radio. See the relevant
sounding system manuals for details. For instructions on using the
Ground Check Set GC25, see Ground Check Set GC25 User’s Guide.
CAUTION
Only touch the bottom of the boom. Do not touch or hit the sensors.
