After 10 minutes (factory preset) without a connection between the device and the external sensor the whole display starts blinking. Pressing READ will stop the display from blinking.

Display status: external sensor error

How to fix the connection error

Please check the following two points:

  1. Is the external sensors properly connected with the device?
  2. Does the external sensor cable have any defects?

Note: As soon as the error(s) have been cleared, the measuring will continue. During max. 1 minute after the connection no temperature is displayed on the screen.
Fix the connection error before stopping the warning. Otherwise new temperature records will not be captured.
During a connection error no data will be recorded.
