When Radiosonde RS41 is connected to Ozone Interface Board OIF, it sends the OIF measurement data through the additional sensor interface. The following information is contained:

  • Instrument type and number
  • Ozone pump temperature
  • Ozone current
  • Battery voltage
  • Ozone pump current
  • External voltage measured once per second

OIF measurement data contains the following information:

xdata= <Instrument type is 05><Instrument number is 01><Ozone pump T [0.01 ºC]><Ozone current [0.0001uA]><Battery voltage [0.1V]> <Ozone pump current [1 mA]><Ext. voltage [0.1V]>CR

This means that if OIF sends

xdata=050108CA186A0750B637CR

it is interpreted as shown in the following table:
