Introduction

The LogTag® TRED30-16R temperature recorder features a data

logging memory storing up to 15,905 temperature readings and a

separate statistical memory, storing maximum and minimum reading

as well as alarm duration for each of the last 30 days.

During recording the display shows the current temperature (of the

most recent reading), the status (within or outside t he 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.

Alarm events can be triggered when a number of readings are outside

pre-set Alarm thresholds and a “day alarm indicator” appears on the

display.

Logged temperature data can be downloaded via a standard LogTag®

Interface to the free companion software LogTag® Analyzer, where

you can display data in chart, list or summary formats. The software

also allows electronic archiving and exporting or transmitting data in

support of sophisticated data management systems.

Features

The TRED30-16R t emperature recorder features the familiar LogT ag®

case layout.

Display

The display shows ‘at a glance’ if alarm events have occurred for both the current day and up to 29 days in the past. Details of any alarm event can be checked directly on the unit by inspecting the statistics history on the recorder's display or in more detail by downloading the logged data.

Sensors

The TRED30-16R will accept any sensor from the ST100 product range.

Checklist - Required Equipment

l LogTag® TRED30-16R temperature recorder.

l A computer running Windows 7 or later. l A LogTag® interface cradle for configuring and downloading the

TRED30-16R.

l LogTag® Analyzer installed and ready to go.

Configuring the TRED30-16R

Before a TRED30-16R recorder can be used, it must be configured with the parameters required for starting and recording temperature values. This is done using LogTag® Analyzer software, which is also used for downloading and analyzing data.

l Start the LogTag® Analyzer software.

l Plug a LogTag® interface cradle into a USB port and wait for the

drivers to be installed. You can use more than one cradle to configure multiple devices at the same time, however it is practical to limit the number of units to about 6, using a powered USB hub.

l Insert the TRED30-16R into the interface with the three contacts

towards the back until it clicks in place.

l Select LogTag - Configure; LogTag® Analyzer will scan all USB

ports and display the configuration options for connected TRED30-16R‘s.

Figure 1: TRED30-16R features

Case

l Mounting lug for secure fastening of recorder to fixtures l Gold-plated, high-quality temperature sensor socket l Robust polycarbonate case, IP64 l Durable communications contacts

Buttons

START/CLEAR/STOP button; can be used to start and stop the

unit or to clear an alarm. It is also used to exit the statistics review.

REVIEW/MARK but ton; can be used to enter the statistics

review and to scroll through the statistical data directly on the display. It is also used to place an inspection mark in the data listing.

Standard Configuration Options

The standard configuration options are very similar to those of other

LogTag® recorder products and include settings such as User ID,

start method, pre-start recording, logging interval and duration,

start delay, and password.

Figure 2: TRED30-16R Standard Configuration Options

For detailed information about each parameter please read the section

about Configuring a LogTag® for logging in LogTag® Analyzer’s

User Guide or press F1 for help.

Each alarm trigger condition consists of a threshold temperature value, an act ivation type (which can be instant, consecutive or accumulative1) and a delay time, if it is not an instant alarm. If an alarm trigger condition requires readings to exceed an upper threshold temperature it is called an upper alarm. If an alarm trigger condition requires readings to go below a lower threshold it is called a lower alarm.

The alarm triggering structure in the recorder supports many different alarm trigger configurations.

For example, a possible alarm trigger configuration could be:

l Upper alarm is triggered when the temperature is 10°C or above

for an accumulative time of 10 hours.

Lower alarm is triggered when the temperature is -0.5°C or below continuously for 1 hour.

TRED30-16R Start Options

During configuration with LogTag® Analyzer you can decide when

the TRED30-16R starts taking temperature readings.

l ... via Push button start: The recorder will start taking

temperature readings after you have gone through a specific start sequence of pressing and releasing the START/CLEAR/STOP

butt on (see Starting the Recorder on page 9).

l ... via Date/Time start : The recorder will start t aking

temperature readings at the date and time you specify (local time).

When you choose the push button start option, you can select to

record pre-start readings or Begin recording after a delay.

l If you configure the TRED30-16R to start after a delay period, the

recorder will not immediately record temperature readings after you have pressed START/CLEAR/STOP, but start a countdown

timer instead, and record readings only after the timer has ended.

It will, however, continue to take pre-start readings, if enabled. You cannot combine a date/time start with pre-start readings or the start delay funct ion.

Alarm Configuration Options

The TRED30-16R can display an alarm if either of the configured alarm trigger conditions have been met. This is indicated on the display by showing the Alarm Indicator ( ) and the Day Alarm

Marker for today ( ).

Figure 3: S ample Alarm Configuration Settings

All alarm trigger conditions are configured using LogTag® Analyzer, please see the Standard Configuration Options above.

Once an alarm has triggered, the alarm indicator ( ) remains shown until the alarm is cleared (see Clearing an Alarm on page 11).

The day alarm marker remains shown until midnight, then it

turns off and the marker for the previous day is shown ( ) to indicate the alarm was registered against what is now the previous

day. When midnight passes next, this marker will move to and so on. Once an alarm event occurred, all alarm counters are reset, and the alarm processing starts again. Accumulative or consecutive alarms will re-trigger, if the alarm conditions are met again, and the A larm

Indicator ( ) and the Day Alarm Marker ( ) will be shown once again.

Alarm Re-triggering

Instant = one temperature reading is above (below) the th reshold

Consecutive = temperature readings are above (below) the threshold for the time defined in th e activation de lay without interruption

Accu mulative = temperature readings are above (below) the threshold for the total time defined in th e activation delay time, but may not necessarily be sequential.

Audible Alarm

The TRED30-16R is fitted with a beeper, which can be turned on when an alarm event has been registered to provide extra feedback. This function is enabled or disabled when configuring the recorder with LogTag® Analyzer, please see the Standard Configuration

Options on the previous page or the Sample Alarm Configuration Settings on the previous page.

Please note, that c ontinual activation of the audible alarm will reduce the working life of the battery. When an alarm event is triggered, the alarm should be cleared as soon as possible.

The alarm will sound once every four seconds for the first 24 hours. To preserve battery life, the interval at which the alarm sounds will increase to 8 seconds when the clock passes midnight after the initial 24 hour period (i.e. the alarm will sound every 4 seconds between 24 and 48 hours, depending on when during the day the alarm was first triggered). When the clock passes midnight again, the interval changes to 12 seconds. It will remain at 12 seconds until the alarm is cleared, the unit stops or is re-configured.

Note: The interval will increase, even if the alarm is re-triggered! Please see more information about Alarm Re-triggering on the previous page

The beeper will temporarily turn off when you are reviewing data.

Advanced Configuration Options

Select Advanced Options for additional configuration settings. These settings decide how some of the elements are displayed on the screen and set certain options specific to the TRED30-16R.

Display Overview

Figure 5: Display Overview with all segmen ts turned on

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 4 character, 7-segment display shows the last recorded temperature while the TRED30-16R is recording . Once the recorder has stopped, nothing will be displayed.

Day Number

During Review, t his shows the day number of the currently displayed

day statistic. Today is 00 DAYS, days in the past are represented between yesterday -0 1DAYS and -29 DAYS. During configuration of

the recorder 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 TRED30-16R's battery is low and requires changing. Please follow the instructions provided in Appendix 1 - Battery

Replacement on page 17. 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 TRED30-16R 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 TRED30-16R is currently recording data.

If the READY symbol is shown, the TRED30-16R is ready to be started. Depending on the configuration it may already record pre-

start readings.

If the STARTING symbol is shown, the recorder 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 TRED30-16R 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 TRED30-16R has finished recording temperature data.

Time Value and Time Indicators

The time value display is used to show one of the following:

l a clock with the current time, l time remaining to start of logging with a delayed start or l 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 dt s tappears in place of a time value if the recorder 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 t he 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.

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). This is the primary function of the display clock.

Each time the recorder is configured with LogTag® Analyzer the display clock value is set to the PC's current local time (or timezone). The time can also be adjusted directly on the unit using the buttons (see

Adjusting the Display Clock below).

Note 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, which would be the case if the real time clock were to be changed together with the display clock.

LogTag® Analyzer can display the logged readings in the following times:-

l UTC (GMT) l Configuration time zone l Download timezone l Display clock timezone (default)

Adjusting the Display Clock

The display clock of the recorder can be set to the correct time, either by using LogTag® Analyzer software or directly on the unit, using the butt ons.

To set the clock, press and hold the button, then press and hold the

button. Keep holding both buttons together continuously for a

period of 8 seconds. Press the buttons firmly!

During this period the CLOCKADJ icon flashes. Release the buttons when the flashing stops. The clock can now be adjusted.

Initially, the minutes digits flash.

Accept the hours value by pressing . The new clock value is now stored, and the display shows the normal screen.

NOTE: It is advised that t he real time clock is only adjusted when the product is not recording (STOPPED or READY) to avoid large shifts in day boundary data.

If a display clock adjustment is made while in RECORDING mode, the next log taken will be identified in the downloaded data with a time change mark.

Changes to the display clock do not affect the internal real time clock value, so the logged data does not show time gaps.

Press the button to increment the minutes digit (once it reaches 59 it rolls back to 00 on the next press).

Accept the minutes value by pressing . The hours value now flashes.

Press the button to increment the hours digits (once it reaches 23 it rolls back to 00 on the next press).

Starting the Recorder

Push button start

The recorder must be in READY mode for it to be started.

Current time and the READY symbol are shown.

Press and hold the START/CLEAR/STOP button. First, STARTING is shown in addition to READY:

Then READY disappears:

Push button start, quickstart disabled

Again, the recorder must be in READY mode for it to be started.

Press and hold the START/CLEAR/STOP button. The STARTING symbol starts flashing for about 4 seconds. Then the symbol remains on

permanently for 2 seconds. If you release the but ton during this time,

The symbol is shown, the STARTING symbol goes off and the recorder starts taking temperature readings.

If the but ton is released earlier than 4 seconds or later than 6 seconds,

the display shows READY again, and t he recorder does not start.

Once READY disappears, release the button within two seconds.

STARTING will also disappear, and the symbol will be shown.

The TRED30-16R now records temperature data.

The recorder will not start if you…

…

release the button before READY disappears

…

keep holding the button for more than 2 seconds after READY disappears.

Push Button Start with Start Delay

If the recorder has been configured for push button start with a start

delay (regardless of quickstart settings), t he word DELAY is shown instead of the symbol.

The delay time is shown in hours and minutes. The time counts down

and the TRED30-16R starts recording when it reaches 0:0 0.

Automatic date/time start

If you configured the TRED30-16R for a date/time start, it will start recording temperature values as soon as the entered start time is reached. T he recorder will display the following if a Date/Time Start has been chosen:

Hibernating the recorder using LogTag® Analyzer will disable the Date/Time start function.

The timer can be cancelled and the recorder re-set to READY.

While STARTING and DELAY are shown, press and hold the

START/CLEAR/STOP button. STOPPED will now show. Release the

butt on when STARTING disappears.

STOPPE D and DELAY will both disappear, and READY will show,

together with the current t ime, and the recorder can now be started again as normal.

The TRED30-16R will not be re-set if you …

…

release the button before STARTING disappears, or

…

if you keep holding the button until STOP PED disappears.

During Recording

During normal operation the display shows the most recently recorded temperature. This temperature is updated at the same rate as the logging interval. The current time is also displayed (in 24 hour format).

A tick symbol is shown as long as no alarm event has occurred. If an

alarm event is registered, a cross symbol is shown instead of the tick.

At the bottom of the display you can see an alarm day summary, where any days on which an alarm was recorded are highlighted.

Following are some sample display screens:

At 1:29 pm the display shows the following:

l Alarm events were recorded 7, 19, 20 & 25 days ago l These alarms were cleared by an inspector, as the display currently

shows the OK tick ( ).

l The current temperature is over the upper alarm threshold, as

indicated by the upper alarm marker ( ).

l the duration, however, of this temperature excursion has not yet

triggered an alarm

At 1:49pm (20 minutes later) the display shows the following:

l The temperature has remained above the upper alarm threshold

and has now triggered an alarm event. l The alarm symbol is shown to indicate an alarm event occurred l

The day marker for the current day ( ) is shown.

Marking a reading with an inspection mark

When you press the REVIEW/MARK button, the next reading taken by the TRED30-16R will be identified in the downloaded data with an

inspection mark.

An inspection mark will also be recorded if you clear an alarm.

Clearing an Alarm

During configuration with LogTag® Analyzer you can allow a user to clear an alarm on the display. This is a useful function for an inspector, so new alarms can be recognised easier.

This display screen shows an existing alarm that occurred yesterday, but has not yet been cleared:

To clear this alarm (quickstart enabled), press and hold the

START/CLEAR/STOP button.

After approx. 2 seconds the cross will be replaced with t he tick . Release the button when the tick appears. The normal recording display is shown.

If the quickstart option is disabled, the symbol will flash for approx. 6 seconds. When the symbol remains permanently on, release the butt on within 2 seconds. The symbol now turns off, and the alarm is cleared.

The alarm will not be cleared if you …

…

release the button before the appears, or

…

if you keep holding the button after the appears until the cross

appears again. … release the button before the symbol remains permanently on, or … if you keep holding the button after the symbol remains

permanently on for more than 2 seconds.

In this example the paused function was activated, and the paused symbol is shown on the display. For more information about paused readings please see the section about Paused Readings on the next page.

At 1:49am on the next day the display shows the following:

A mark will be placed in the readings when you clear an alarm.

l The temperature has returned to within the accepted range (none

of the alarm threshold markers are visible), but the alarm remains present, as it has not been inspect ed and cleared

l The day summary has shifted by 1 day as the display time has

passed through midnight (00:00).

Note: Only the Alarm Indicator can be cleared! The day alarm marker

( in the above example) remains shown, as it is part of the statistic summary.

Paused Readings

During configuration of the TRED30-16R you can set the option to ignore up to 15 readings for alarm- and statistics calculations after either butt on is pressed. The readings are still shown on the graph and in the data listing, but they are labelled as paused, and their value is ignored when determining alarm trigger conditions, minimum/maximum values and other statistical calculations. This function is useful when you wish to review readings during the recorder's operation (or clear an alarm), but you do not wish to trigger an alarm due to your handling the product. It also allows the recorder to acclimatise to the environmental conditions again, before furt her readings are processed.

After a button press the display shows the word PAUSED next to the

symbol.

Paused readings are specially marked in the graph and data listings.

The option is set in the advanced options dialogue in LogTag® Analyzer during configuration and is expressed in number of readings after the last button press (see Advanced Configuration Options on page 6).

PAUSED will turn off as soon as the last ignored reading has been

recorded. It will show longer, if your last button press was just after the recorder took a temperature reading, but will be displayed for a short er period if you pressed the butt on just before a reading is taken. With the options configured in the example on page 5 and on page 6 the time for

PAUSED to show could be as short as 10 minutes, but as long as 20

minutes.

If the sensor was disconnected for a complete day, the minimum and

maximum statistics for that day will show --.- on the display and --.on the list.

Power Save

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 only 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 seen frequently, such as in transit monitoring applications.

Pressing any button will re-activate the display.

The power save mode is enabled or disabled when configuring the TRED30-16R via LogTag® Analyzer in the Advanced Options dialogue (see Advanced Configuration Options on page 6).

Note: The display will not turn off if there is a pending alarm!

Total Number of Days Statistics Collected

The recorder can be configured to show the total number of days for which statistics data was collected. This feature is enabled when configuring the TRED30-16R via LogTag® Analyzer and can be located in the Advanced Options dialogue (see Advanced Configuration

Options on page 6).

When enabled, the total number of days for which statistics data was collected are shown on both the Recording Display and the Stopped

Display.

Sensor is disconnected

The display shows --.-, if the external sensor of the TRED30-16R is disconnected. This function is useful if the sensor is permanently

mounted , but you wish to take the TRED30-16R to a computer for downloading its data.

Any values recorded during the time the sensor is disconnected 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.

After downloading the TRED30-16R with LogTag® Analyzer, any readings taken while the sensor is disconnected are shown as --.- in the data list. The graph will show a gap during this period.

Figure 6: TRED30-16R re cording, showing ‘18’ days of data has been collected.

Figure 7: TRED30-16R stopped, showing ‘27’ days of data has been collected.

Note, this is not always the number of days the recorder has collected data. Depending on the sampling interval the recorder can hold more than 30 days of temperature readings, but since the maximum number of days for which statistics can be collected is 30, the highest number that can be shown here is 30.

Reviewing Day Statistics on the TRED30-16R

The review of day statistics history is accessed by pressing the

REVIEW/MARK but ton .

You can review the data regardless of whether the recorder is still logging data, or has already been stopped.

Following are some sample display screens you might see during a statistics review. All display screens are based on the alarm settings made in Alarm Configuration Options on page 5:

Today's data

Pressing the button displays the current day’s maximum statistic:

l the duration value shows the amount of time recorded above the

limit yesterday, which was 12 hours 30 minutes

l an alarm was triggered, indicated by the , as this duration was

longer than the allowed time above the threshold

l The maximum temperature recorded yesterday was 12.9°C.

Pressing the button now displays yesterday’s minimum statistic:

still flashes and -0 1 DAYS still shows, as we are still looking

at yesterday's data.

l Yesterday, no temperature values were recorded below the lower

alarm threshold. The alarm for the day was generated by the

upper alarm, not by the lower alarm, so a is displayed in t he

minimum statistics.

l The minimum temperature recorded yesterday was 2.0°C.

The Today marker flashes and 00 DAYS is shown to indicate that today's data are being displayed.

l Today, no temperature values were recorded above the upper alarm

threshold, and no alarm event was generated ( ). l The maximum temperature recorded today was 4.8°C. l The paused function is enabled

Pressing the button again displays the current day’s minimum statistic:

still flashes and 00 DAYS is still shown, as the same day's data

(today) is being displayed. l Today, no temperature values were recorded below the lower alarm

threshold, and no alarm event was generated. l The minimum temperature recorded today was 1.4°C.

Yesterday's data

Pressing the button now displays yesterday’s maximum statistic:

Data from the day before yesterday

Pressing the button now displays the maximum statistic from two days ago:

The flashes and -02 DAYS is shown to indicate that the data being displayed is from two days ago.

l Two days ago recordings above the upper threshold were recorded,

indicated by the upper alarm threshold marker

l The duration was 1 hour 20 minutes, which was shorter than the

allowed period, so no alarm event was generated

l The maximum temperature recorded on the day before yesterday

was 11.5°C. Pressing the button now displays the minimum statistic from two days ago:

still flashes and -0 2 DAYS still shows, as we are still looking

at the data from 2 days ago.

l Yesterday, no temperature values were recorded below the lower

The -1 marker flashes and -01 DAYS is shown to indicate that yesterday's data is being displayed.

l Yesterday, recordings above the upper threshold were recorded,

indicated by the upper alarm threshold marker

alarm threshold, and no alarm event was generated .

l The minimum temperature recorded on the day before yesterday

was 7.8°C.

Data from 7 days ago

After pressing the button for a few times (skipping days -3 to -6) the maximum statistic from seven days ago is displayed:

Stopping the TRED30-16R

Automatically

The TRED30-16R automatically stops recording temperature when the maximum number of readings specified during configuration has been reached. Your unit can also be set up to stop automatically when it is downloaded. This option needs to be set up at the factory and cannot be changed during configuration with LogTag® Analyzer. Your distributor can supply more information about this option.

The flashes and -07 DAYS is shown to indicate that the data being displayed is from seven days ago.

l Seven days ago recordings above the upper threshold were recorded,

indicated by the upper alarm threshold marker

l The duration was 6 hour 30 minutes, which was shorter than the

allowed period, so no alarm event was generated

l The maximum temperature recorded seven days ago was 10.5°C.

Data from 8 days ago

After pressing the button twice (skipping the minimum statistics for day -7) the maximum statistic from eight days ago is displayed:

The flashes and -08 DAYS is shown to indicate that the data being displayed is from eight days ago.

l Eight days ago recordings above the upper threshold were recorded,

indicated by the upper alarm threshold marker l The duration was 5 hour 30 minutes l An alarm event was generated . Neither duration from day -7 or -8

by itself would cause an alarm event, however the combined

duration is 10 hours 50 minutes, which is more than the allowed 10

accumulative hours. l The maximum temperature recorded eight days ago was 11.5°C.

Tip: Pressing and holding the button will get you back to the previous screen, rather than advancing one screen.

Manually

You can configure a TRED30-16R so it can be stopped with the

START/CLEAR/STOP button. This feature is useful when you take the

recorder out of a shipment and don’t want to falsify the statistics with readings taken after the shipment completion. The stop function is enabled in the Advanced Options dialogue during configuration (see

If an ALARM is present ( ) and the Clear alarm by pressing STOP

button function is enabled, you will need to clear the alarm first

before you can stop the recorder. Please see Clearing an Alarm on page 11 for more information on how to clear an alarm.

Once the recorder has stopped, t he alarm status will no longer be indicated with a cross or a tick symbol, and the audible alarm will turn off.

Resetting the Recorder

You can reset a recorder back to its original READY state. Once re-set, recording can be started again as described in Starting the

Recorder on page 9.

Note that when performing this procedure all recordings and statistics stored in the recorder are deleted and cannot be recovered. Please ensure your data has been saved!

This is useful for conserving battery life when the recorder is not used for extended periods .

TRED30-16R recorders are placed into Hibernation using LogTag® Analyzer by clicking Hibernate on the LogTag menu.

The display shows SLP for a few seconds, before turning itself off.

A hibernated recorder has no active display, however a button press will wake the recorder up briefly. The display will show:

the low battery symbol if the battery requires replacing.

the t ext n o t rd Y if the battery is OK, and the recorder can be reactivated at a later point.

For this process to work, the recorder must be in the STOPPED state.

Press and hold the button. T he READY symbol will flash.

When the READY symbol remains permanently on, release the

butt on within 2 seconds. The recorder is now ready to be started

again.

The ability to reset a recorder is enabled or disabled in the Advanced

Options dialogue when configuring the TRED30-16R via LogTag®

Analyzer (see Advanced Configuration Options on page 6).

A hibernated recorder can be activated again by pressing and holding the and buttons together for a period of 6 seconds. During this

time the text n ot r dY appears and the READY symbol flashes. Release the buttons when the flashing stops.

You can re-activate a recorder with a low batt ery, however it is not recommended t o commence another trip.

Note: The real time clock is not running in a hibernated recorder and must be set up if the recorder is manually activated. Therefore, the

CLOCKADJ procedure is automatically invoked (see Adjusting the

Display Clock on page 8).

Once the clock has been set, the recorder is ready to be started again.

Hibernating a TRED30-16R

When hibernated, the recorder’s power consumption is near zero and the life of the battery approaches its shelf life (typ. 5 or more years).
