Readout mode
In order to avoid incorrect data, the Fridge-tag does not measure the temperature while settings are
changed or during Readout mode (e.g. changing time, date and during reading of history). The Fridge-
tag will fall back into normal operation after approx. 60 seconds without pressing any buttons. The LOC
function will be activated (internal sensor).
External sensor: After 10 minutes (factory preset) without connection between external sensor and
device the entire display starts flashing.
HI or LO indicator: If the Fridge-tag measures temperatures above +55°C or below –40°C, it shows HI
or LO on the screen. The regular measurements and monitoring of alarm limits will continue as usual. As
soon as the temperature is between +55°C and –40°C numbers will be displayed again.
