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 USB-receiver
2. Problems in the temperature sensor module
3. Problems in the signal transfer between temperature sensor
module and USB-receiver
1.1. Problems inside the USB-receiver
The receiver 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-module
- Unknown software problem in the computer system
- Internal battery BS-510 is empty
(replace the battery)
Suggested solutions:
- Check the display window in the temperature logger display

‘ready’ continously. If the display intermittently displays
‘RF_USB-Communication failure’, the Windows operating

- 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 BS-510 clock baery (Type CR2032)
The lifeme of the BS-510 baery is about 5 years!
