Day Alarm Markers
This grid shows 3 rows of 10 markers, named Today (
) to Day -29 (
), which are switched on when an alarm event occurred on that day.
Temperature
This shows the last recorded temperature while the UTRED30-WiFi is recording. Once the logger has stopped, nothing will be displayed.
Day Number
During Review, this shows the day number of the currently displayed day statistic. Today is 00 DAYS, days in the past are represented between yesterday -01 DayS and -29 DayS. During configuration of the logger in LogTag® Analyzer you can also enable this to show the total number of days on which data were collected while recording.
Battery Low
A battery test is performed hourly. The battery low symbol 
will appear if the UTRED30-WiFi's battery is low and requires changing. Please follow the instructions provided in Appendix 1 - Battery Replacement. If the symbol is not shown while the display is turned on, the battery is still OK.
ALARM/OK indicator
The 
symbol is shown as soon as the UTRED30-WiFi has registered an alarm event. If no alarms have been registered, or if an existing alarm has been cleared, the 
symbol is shown.
Recording state indicators
The recording state indicators show if the UTRED30-WiFi is currently recording data.
- If the Ready symbol is shown, the UTRED30-WiFi is ready to be started. Depending on the configuration it may already record pre-start readings.
- If the Starting symbol is shown, the logger has been configured with a start delay. The word DELAY is also shown, together with the time in hours and minutes until the start.
- If the
symbol is shown, the UTRED30-WiFi is recording temperatures at the sample interval defined during configuration with LogTag® Analyzer. - If is shown together with the word Paused, the product is also recording, but the recorded values are not taken into account when calculating alarm events and durations.
- If the word Stopped is shown, the UTRED30-WiFi has finished recording temperature data.
Time Value and Time Indicators
The time value display is used to show one of the following:
- a clock with the current time,
- time remaining to start of logging with a delayed start or
- duration, for example of an alarm.
The time indicators identify, which of those is displayed:
- If the word TIME is shown, the time value represents the current time in hours and minutes (24- hour format).
- If the word deLay is shown, the time value represents a start delay in hours and minutes.
- If the word duRatIoN is shown, the time value represents the length of time in hours and minutes an alarm threshold was exceeded, for example the time above the upper alarm threshold.
The word dtstappears in place of a time value if the logger is configured for a date/time start, and the start time has not yet passed.
Reading Type
The word Current is shown when the temperature on the display represents the last recorded temperature.
The word MAX is shown in Review mode, when the temperature on the display represents the maximum recorded temperature for the day displayed.
The word MIN is shown in Review mode, when the temperature on the display represents the minimum recorded temperature for the day displayed.
Alarm Threshold Markers
The up-arrow 
is shown when the temperature displayed (i.e. last recorded) is above the specified upper temperature threshold. The down-arrow 
is shown when the temperature displayed is below the specified lower temperature threshold.
Temperature Units
Depending on the selected display temperature units during configuration, this shows either °F or °C.
