TRED30-7 : Temperature Recorder with 30 day summary display PRODUCT SPECIFICATION Doc v 1.0 14/06/11 page 3/22
Overview
The LogTag®TRED30-7 Remote Probe temperature recorder features a data logging memory storing
up to 7770 temperature readings and a separate rolling 30 day statistical max/min reading and duration
memory.
During recording the display shows the current temperature (of the most recent reading), the status
(within or outside the acceptance range), an alarm trigger summary of up to the last 30 days (today and
29 days previous) of recording, the current time and battery status.
If a reading is outside the pre-set “Alarm” limits an alarm is generated and a “day alarm indicator”
appears on the display.
This display arrangement is designed to show ‘at a glance’ if temperature excursions have occurred for
both the current reading and up to 30 days in the past. Details of any excursions can be checked
directly by inspecting the statistics history on the recorder’s display or in more detail by downloading the
logged data.
Logged temperature data can be downloaded via a standard LogTag®Interface to the free companion
software LogTag Analyzer which provides facilities for displaying data in chart, table or statistical
formats and allows electronic archiving, export or transmission of the data in support of sophisticated
data management systems.
A number of Remote Probe options are available ST100x-xx (see page 21,22).
Button Actions Overview
Start/Stop/Clear button functions require the button to be pressed continuously for 4 seconds and then
released when the related flashing indicator stops flashing. This reduces the possibility of vibration or a
load being placed on the recorder that causes permanent or intermittent button press to falsely trigger a
function.
Review mode is exited immediately by pressing the STOP button.
Review/Mark button
Press to enter REVIEW mode and then press again to
advance through the day statistics.
This action also places an inspection mark in the log if
recording is active
Start/Clear/Stop button
Press to start recording
Press to clear alarm (if function enabled)
Press to Stop recording (if function enabled)
Press to exit day summary review.

Alarm triggering and function.
A visual alarm trigger is displayed if one or more of the configured alarm trigger conditions
have been met. An alarm trigger condition can be a single violation reading (a reading above the upper
or below the lower threshold value), a set of consecutive violation readings or a total of violation
readings encountered (called ‘accumulative’).
The alarm triggering structure within the recorder supports many different alarm trigger configurations..
For example, a possible alarm trigger configuration could be :-
High Trigger when temperature is 10°C or greater for an accumulative time of 10 hours.
Low Trigger when temperature is -0.5°C or below for continuous 1 hour.
This is configured in using LogTag Analyzer as shown below :-
Note: Accumulative or consecutive alarms automatically retrigger after the configured delay if the
temperature remains in violation.

TRED30-7 : Temperature Recorder with 30 day summary display PRODUCT SPECIFICATION Doc v 1.0 14/06/11 page 6/22
Real time clock
The time shown on the recording display is linked to the recorder’s internal real time clock.
A day change occurs when the display time rolls through midnight (i.e 00:00) and this is the main
function of the display clock.
The display clock value is set to the current time (or timezone) when the recorder is configured with
LogTag Analyzer and can be also directly adjusted using button actions. (see Adjusting the display
clock)
Note however that the recorder’s internal real time clock value is only updated when the recorder is
configured with LogTag Analyzer. This prevents the data logging becoming discontinuous with changes
to the real time clock.
LogTag Analyzer can display the data logged readings with the following time stamp options:-
UTC (GMT)
UTC + configuration time zone
UTC + download timezone
UTC + display clock timezone (default)

Reviewing day statistics
The Review of day statistics history is accessed by pressing the REVIEW button and is
accessible in RECORDING and STOPPED modes.
An example of a reviewing days statistics is shown below :-
Pressing Review button displays current day’s
max statistic.
The “Today” segment flashes and ‘Day 00’ is shown to
indicate the ‘Today’ selection.
In this screen example the selected day (Today) does
not have any recordings that are outside the
acceptance range.
Pressing Review button again displays the
day’s minimum statistic.
Pressing the Review button again
displays the next previous day’s max statistic.
In this screen example the selected day has recordings
that are above the upper limit and the duration value
shows the amount of time recorded above the limit.
The max statistic is above the upper limit so the up
arrow is shown and an alarm was triggered by this
statistic as indicated by the ALARM text shown.
Pressing the Review button again
displays the day’s minimum statistic.
The min statistic is not below the lower limit and did not
trigger an alarm.

TRED30-7 : Temperature Recorder with 30 day summary display PRODUCT SPECIFICATION Doc v 1.0 14/06/11 page 12/22
Pressing the Review button again
displays the next previous day’s max statistics.
The “-2day” day marker flashes and DAY ‘-02’ is
displayed.
In this screen example the selected day does have
recordings that are above the upper limit however did
not exceed the alarm trigger durations so only the up
arrow is shown and no ALARM trigger has occurred
Pressing the Review button again
displays the day’s minimum statistic.
Each time the Review button is pressed the cursor
advances to the next previous day.
If less that 30 days of recordings have been collected
so far then the day marker only advances as far as
there is data available after which the next press rolls
the summary back to the statistic for Today
Pressing the button at any time reverts the display back to the normal mode.
The display will revert back to normal mode after 30 seconds of no button activity.
Note
1. If exposure to alarm temperatures occurs in a continuous period of time that is cut with the day shift
(midnight) then the time count continues and if the alarm period is finally exceeded then the day in
which the time count was completed is displayed with day alarm indicator and the time exposure split
appropriately over the two days.
2. The duration values above or below the specified High/Low temperature are always displayed.
Presence of a day alarm trigger marker means that exposure to an alarm temperature for a continuous
period greater than the configured trigger duration has occurred on that day.

Paused function
The recorder can be configured to suspend processing of readings for alarms and max/min statistics for
a period of time after button press activity.
This allows the user to review the current statistics or clear an alarm without causing a false alarm or
statistic while handling or re-positioning the external probe.
The delay is expressed in multiples of logging interval and is set in the LogTag Analyzer Configure
TRED - Advanced Options configure dialogue.
Paused processing is indicated on the display by the PAUSED icon being present as shown in the
display example below :-
Note
Data logging continues but each log that is taken during the paused period is flagged and labelled as
paused. Logs that are flagged as ‘paused’ are not used in the summary statistics.

Power save mode
When Power save mode is enabled the display will automatically switch off after 30 seconds of no
button activity.
The recorder uses significantly less battery power with the display off (typically to around 1/3 of the
average power with the display on).
This function is appropriate in applications where the current temperature display is not required to be
often seen such as a transit monitoring application.
Press any button to cause the display to re-activate.
The power save mode is enabled or disabled via LogTag Analyzer software configuration function

Adjusting the display clock
The display clock of the recorder can be set to the correct time zone either by using LogTag Analyzer
software or directly using key actions on the recorder itself.
The clock can be adjusted to local time by pressing the and buttons together continuously
for a period of 8 seconds.
During this button press period icon flashes. Release the buttons when the flashing stops
to enter clock adjustment mode.
The display then changes as shown in the example below with the minutes digits flashing.
In the example below the hours is 18 and the minutes is 38:-
Press the button to increment the minutes digit (rolls
back to ‘00’ after ‘59’ with multiple presses).
Press the button to accept the minutes value and the
display then flashes the hours value.
Press the button to increment the hours value digits
(rolls back to ‘00’ after ‘23’).
Press the button to accept the hours value and the
display then reverts to the normal display.
NOTE: It is advised that the real time clock Hours is only adjusted when in STOPPED or READY
modes (i.e not recording) to avoid large shifts in day boundary data.
If a display clock adjustment is made while in RECORDING mode then the next log taken records a flag
indicating a time change took place.
Changes to the display clock do not affect the internal real time UTC+timezone offset value so the
logged data does not experience time gaps.

TRED30-7 : Temperature Recorder with 30 day summary display PRODUCT SPECIFICATION Doc v 1.0 14/06/11 page 18/22
Hibernation
When hibernated, the recorder’s power consumption falls nearly to zero and the battery life approaches
the shelf life of the battery (typically 5+ years).
This state is useful for conserving battery life during periods of non use.
A hibernated recorder has no active display however a button press will wake the recorder up and it will
display just the battery status for a few seconds then revert back to display off.
A hibernated recorder can be placed into the Ready state by pressing the and buttons
together continuously for a period of 6 seconds.
During this button press period the READY icon flashes. Release the buttons when the flashing stops to
enter READY state.
Recorders can only be placed into Hibernation with LogTag Analyzer.
Note
The real time clock is not running in a hibernated recorder and must be setup once hibernation is
manually exited to the READY state (see ‘Adjusting the display clock’).
