Chapter 3 ________________________________________________________________ Operation CHAPTER 3 OPERATION This chapter contains information that is needed to operate this product. General It is essential that you carry out the pre-launch steps as instructed and always in the same way. Follow the instructions in the sections below and refer to Appendix A on page 39 for proper and safe balloon preparation. The workorder for a sounding is as follows: 1.
User's Guide ______________________________________________________________________ Preparing the Balloon and Optional Sounding Accessories The balloon and the optional sounding accessories must be prepared before connecting the radiosonde battery and thereby activating the radiosonde. This is necessary because the radiosonde should be launched within 15 minutes of battery connection. WARNING Read the safety instructions in Appendix A before proceeding.
Chapter 3 ________________________________________________________________ Operation 2. Attach the balloon to the gas nozzle by securing the balloon with a piece of string or a clamp. 0705-017 Figure 3 3. Inflate the balloon following the balloon manufacturer’s inflation instructions. Do not leave the balloon-filling shed while inflating the balloon. 0705-018 Figure 4 4.
User's Guide ______________________________________________________________________ 0705-019 Figure 5 5. Balloon Raises the Gas Nozzle Secure the neck of the balloon tightly with a string before removing the balloon from the gas nozzle.
Chapter 3 ________________________________________________________________ Operation 0705-021 Figure 7 6. Fold the neck of the balloon over and secure it firmly. Tie the string high enough to ensure that the unwinder fits easily. 0705-022 Figure 8 7. Removing the Balloon from the Gas Nozzle Folding the Neck of the Balloon Leave the balloon waiting in the balloon-filling shed while you prepare the radiosonde. Make sure the balloon does not touch anything. Hold the balloon by the neck.
User's Guide ______________________________________________________________________ NOTE When using a balloon with an integrated parachute, make sure that a sufficiently long piece of the parachute string is poking out of the balloon neck in order to fasten the string to the radiosonde unwinder. Optional Sounding Accessories The RS92 unwinder RSU911 is designed to be attached directly to the folded balloon neck.
Chapter 3 ________________________________________________________________ Operation See Figure 9 on page 20 for details. For unwinder attaching instructions, see section Totex Parachute on page 29. Radar Reflector Attach the unwinder to the radar reflector with a rubber plate accessory (Vaisala code RS46158). The rubber plate accessory lets the unwinder swing properly, making sure that the suspension string is unwound smoothly. 1.

Chapter 3 ________________________________________________________________ Operation Unpacking the Radiosonde Follow these steps to unpack the radiosonde: CAUTION Do not touch or hit the sensors on the sensor boom. By carefully handling the radiosonde and the sensor boom, you ensure that the radiosonde functions properly during the sounding. 1. Open the foil bag as indicated on the bag. 0912-232 Figure 10 2. Opening the Foil Bag Lift the cardboard flap protecting the sensor boom.
User's Guide ______________________________________________________________________ 3. Remove the radiosonde from the package, straighten the antenna, and take the unwinder out of the package. 1002-102 Figure 12 4. Placing the Antenna Into Flight Position Remove the small plastic rubber wire from the unwinder. 0601-048 Figure 13 Unwinder Details 1 = Rubber wire 2 = Unwinder lip 5. Make sure the plastic lip under which the string runs is level with the unwinder bottom plate.
Chapter 3 ________________________________________________________________ Operation Preparing the Sounding 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. Follow these steps to prepare the sounding: CAUTION 1. Start a new sounding with the sounding system.
User's Guide ______________________________________________________________________ 0905-083 Figure 14 Placing the Sensor Boom into Flight Position The sensor boom is now in the flight position and remains so throughout the sounding. Now proceed to connect the radiosonde battery.
Chapter 3 ________________________________________________________________ Operation Connecting the Battery Set General The RS92-D battery set ordering codes are given in Table 4 on page 25.
User's Guide ______________________________________________________________________ Connecting the Battery Follow these steps to connect the battery to the radiosonde: 1. Open the foil bag as indicated on the bag. 0912-138 Figure 16 2. Battery Package Take out the battery connector (number 1 in Figure 17 on page 26) by gently pulling the wires.
Chapter 3 ________________________________________________________________ Operation 3. Connect the battery connector (number 1 in Figure 18 on page 27) to the radiosonde (number 2). 0912-141 Figure 18 Connecting the Battery Connector to the Radiosonde 4. The radiosonde has now been activated. Close the battery case. 5. Check from the sounding system software that the telemetry link is working well. For detailed instructions on using the sounding software, refer to the sounding system user manuals.
User's Guide ______________________________________________________________________ Removing the Battery Case If you need to remove the battery case from the radiosonde, use, for example, a small coin to loosen the battery case. Push the coin into the small opening between the radiosonde and the battery case to loosen the case and remove it. See Figure 19 on page 28. 0809-005 Figure 19 Removing the Battery Case Launching the Radiosonde The radiosonde is now ready for launch.
Chapter 3 ________________________________________________________________ Operation needed to restrict the movement of the unwinder. For instructions, refer to section Optional Sounding Accessories on page 18. Attaching the Unwinder to the Balloon Follow these steps to attach the unwinder directly to the balloon: 1. Pass the unwinder hook through the loop created by the tied balloon neck. 2. Make sure that the hook comes out the other side, as shown in Figure 20 on page 29.
User's Guide ______________________________________________________________________ other side in the same fashion as with the folded balloon neck (see section Attaching the Unwinder to the Balloon on page 29). Radar Reflector There is a rubber plate attached to the radar reflector. Attach the unwinder to this plate. Non-Totex Parachute There is a hanger board tied to the parachute.
