7.7. Connection error (external sensor only)
After 10 minutes (factory standard) without a connection between the device and the external sensor the
following display appears and:
• The buzzer will beep twice at intervals of three minutes for a maximum of 168 hours (7 days).
• The whole display starts blinking.
• Any button pressed will stop the display from blinking.
• The buzzer only stops if the connection error is corrected. If the error still exists, the buzzer
continuously beeps at a three-minute interval for 168 hours (7 days).
Display status:
external sensor error
How to fix the connection error
Please check the following two points:
1. If 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 and the connection error
buzzer stops to beep automatically. During max. 1 minute after the connection no temperature is
displayed on the screen.
During a connection error no data will be recorded.
