1. Transmission losses
Sometimes transmission losses may arise, indicated by missing
temperature data in the sensor’s curve display.
Data losses may be caused by:
1. Problems inside the transceiver
2. Problems in the sensor module
3. Problems in the signal transfer between temperature sensor
module and transceiver
1.1. Problems inside the transceiver
The transceiver does not registrate a single data signal, even if the
sensor is located at a minimum distance to the receiver.
Potential problems:
- USB-cable between receiver and computer is missing or defect
- Improper installation of the USB driver
- Unknown software problem in the computer system
- Internal battery is empty
(replace the battery)
Suggested solutions:
- Check the display window in the temperature logger display
for a eld in the lower left area. The eld is to display the value
‘ready’ continously. If the display intermittently displays
‘RF_USB-Communication failure’, the Windows operating
system failed to nd the USB-module.
- Remove the USB-cable, wait about ten seconds and reconnect
the cable.
- Deinstall the temperature logger application software and
reinstall it again.
Please check the internal clock baery (Type CR2032)
The lifeme of the baery is about 5 years!
