Sensor is disconnected

The display shows instead of a temperature value if the external sensor of the UTRED30-WiFi is disconnected. This function is useful if the sensor is permanently mounted , but you wish to take the UTRED30-WiFi to a computer for downloading its data.

Any values recorded during this time will not be taken into account when calculating statistics values or alarms.

If, for example, the temperature was above 10 °C for 12 hours (which would normally trigger an alarm event), but the sensor was disconnected for 3 hours during this time, no alarm would be generated.

When evaluating data, any readings taken while the sensor is disconnected are shown as --.- in the data list. The chart in LogTag® Analyzer and in LogTag® Online will show a gap during this period

If the sensor was disconnected for a complete day, the minimum and maximum statistics for that day will show on the display and --.- in the list.

External sensor disconnected

Minimum and Maximum values shown on the display will remain visible and will not be updated until the sensor is plugged back in.
