8. Temperature
8.1 Ambient temperatur (AMB TEMP):
The FLYTEC 3040 is provided with a temperature sensor inside of the housing for the
temperature compensation of pressure sensors, this Ambient temperature is displayed in
the lower display when the Arrow is pointed to AMB TEMP
Notice: the temperature sensor measures the internal circuit board temperature, and not
directly the outside air temperature! The inside temperature of the housing may be higher
or lower than the ambient air temperature, especially when the instrument is exposed to
direct sunlight.
8.2 Envelope Temperature (Env Temp)
The envelope temperature is being transmitted by radio to the radio transmission unit
TT34 (Option). The TT34 radio transmission unit is being switched on automatically by an
active envelope temperature, and is being switched off automatically if the envelope is not
being used any more.
The temperature sensor transmits its data in a cycle of four seconds. During a balloon
event where you find many balloons close to each other the TT34 does not interferes with
each other. In order to avoid interferences each TT34 has an individual identity number
(ID), which is being transmitted with the radio protocol. The 3040 instruments only accepts
radio dates, which are identical with the ID-number registrated in the 3040 instrument.
Note: A received signal with an invalid ID-number is being indicated as „ID“ in the display
field ENV TEMP
