Probe Is Disconnected; Power Save - LogTag Recorders UTREL30-16 Product User Manual

During Recording

Probe is disconnected

The display shows
temperature probe is disconnected. This function is useful if the probe is permanently
mounted, but you wish to take the UTREL30-16 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 -70 °C for
12 hours (which would normally trigger an alarm
event), but the probe was disconnected for 3 hours
during this time, no alarm would be generated.
When evaluating data, any readings taken while the probe is disconnected are shown as -
-.- in the data list. The chart in LogTag
Minimum and Maximum values shown on the display will remain visible and will not be
updated until the sensor is plugged back in.
If the probe was disconnected for a complete day, the minimum and maximum statistics
for that day will show
