Readout mode:
In order to avoid incorrect data, the Fridge-tag does not measure the temperature while settings are changed or during or 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.
External sensor:
After 10 minutes (factory setting) without connection between external sensor and device, two audio signals sound every three minutes for a maximum of 168 hours (7 days) and the entire display starts flashing.
HI or LO indicator (external sensor):
If the Fridge-tag measures temperatures above +0°C (+32°F) or below –95°C (-139°F), it shows HI or LO on the screen. The temperature will not be logged and not be shown in the PDF/ASCII file. The regular measurements and monitoring of alarm limits will continue as usual. As soon as the temperature is between +0°C (+32°F) and –95°C (-139°F) numbers will be displayed again.
