4. Placing the Fridge-tag 2 L

Placing the Fridge-tag 2 L with an internal sensor

The activated Fridge-tag 2 L must be placed immediately after activation (see chapter 5.) in its predetermined location. It is recommended and important to place the device in the center of the refrigerator for an optimal temperature observation. Please do not place the device into a freezer as the screen will freeze and the battery will lose power prematurely.

Placing the Fridge-tag 2 L with an external sensor

Two hours before activating the Fridge-tag 2 L the external sensor must be placed in its predetermined location. It is recommended and important to place the external sensor in the center of the refrigerator for an optimal temperature observation and to avoid any incorrect measurements when starting the device.

For the right positioning of the external sensor within the fridge, please follow the instructions of WHO, CDC or any other governmental requirements of your country.

Internal sensor : Alarm temperature limits must be no lower than

–20°C (–4°F) and no higher than +50°C (+122°F).

External sensor : Alarm temperature limits must be no lower than –35°C (–31°F) and no higher than +55°C (+131°F).

First you have to choose the range of the desired temperature limit. You have the choice between negative and positive temperatures. In case of a positive limit in Fahrenheit you may further choose if the limit shall be equal or above +100°F. This choice is done by repeatedly pressing READ until the desired range is indicated.

Note : The temperature measurement unit (°C/°F) can only be changed after the device is activated in the menu. See chapter

“6. Read and change settings / How to correct setting mistakes.”

(external sensor only)

After 10 minutes (factory standard) without a connection between the device and the external sensor the following display appears and:

• The buzzer will beep twice at intervals of three minutes for a maximum of 168 hours (7 days).

• The whole display starts blinking.

• Any confirmation will stop the display from blinking.

• The buzzer only stops if the connection error is corrected. If the error still exists, the buzzer continuously beeps at a three-minute interval for 168 hours (7 days).

8. Alarm trigger function

8.1. Single-event alarm triggering

The upper or lower alarm triggering is done with a single-event alarm algorithm. Any kind of alarm is triggered if the temperature is continuously out of the preset alarm limits for longer than the preset alarm trigger time.

Upper alarm triggering

Setting upper limit : Temperature >8.0°C, duration >10 hours

For the upper alarm to be triggered the temperature needs to be continuously above 8°C for more than 10 hours.

8°C

>10 h

Alarm triggered : alarm symbol and warning symbol

displayed.

0 h 12 h 24 h

In the example below the sum* of the daily upper temperature deviation is about 20 hours. No alarm will be triggered! The temperature was not continuously out of the preset alarm limits for more than 10 hours in one row.

8°C

No Alarm triggered :

OK symbol on the display.

>9 h >6 h >5 h

0 h 12 h 24 h

* The sum of the deviations is visible in the daily statistics in the column “Cumulative daily time above the limit.”

Lower alarm triggering

Setting lower limit : Temperature <–0.5°C, duration >1 hour

For a lower alarm to be triggered the temperature needs to be continuously below –0.5°C for more than 1 hour.

– 0.5°C

>1 h

Alarm triggered : alarm symbol and warning symbol

displayed.

0 h 12 h 24 h

In the example below multiple low temperature deviations* are occurring. No alarm will be triggered. Each temperature deviation was less than 1 hour out of the preset alarm limits.

– 0.5°C

No Alarm triggered :

OK symbol on the display.

<1h <1h <1h <1h

0 h 12 h 24 h

8.2. Alarm display and confirmation options

Option 1 : Alarm indication “all alarms”

With this option the alarms will be visible on the display with an alarm symbol for 30 days.

By pressing the READ button, the warning symbol

Note

• In this mode only one upper and one lower alarm will be triggered per day.

• The alarm symbol will be present on the display for 30 days.

• The warning symbol !

can be deactivated by confirming all existing alarms in the readout mode.

• The alarm buzzer stops when the alarm is confirmed within the set alarm limits. Otherwise the buzzer pauses for approx. 1 hour and starts again for up to 168 hours (7 days).

* The sum of the deviations is visible in the daily statistics in the column “Cumulative daily time below the limit.”

Option 2 : Alarm indication “unconfirmed alarms”:

The alarms are shown with the alarm symbol until all alarms

(in the 30-day history) have been confirmed as solved by pressing the READ button. Afterwards the display will show the OK symbol until a new alarm is triggered.

3. Temperature is back within the alarm limits. Now the alarm

can be successfully confirmed. (OK symbol) on display.

Note : How the alarm symbol and the warning symbol !

react is specified during configuration of the device in the factory settings.

8.3. Cumulative daily time above/below the limit

The alarm trigger algorithm is based on a single event, although the Fridge-tag 2 L is measuring on a daily basis the individual total time above or below the temperature limits. This measurement is not used for any alarm condition. These recordings are only available in the generated PDF/ASCII files.

Note : It could be that the total cumulative time above/below the temperature limits is longer than the configured single-event alarm time without any alarm triggering.

–0.

5°C

<1 h <1 h <1 h <1 h

Example setup : lower temperature limit

< – 0.5°C, duration

>1 hour

0 h 12 h 24 h

In the above example multiple low temperature deviations with exposure times of less than 1 hour occurred.

The cumulative daily time below the limits adds up to about 3.5 hours but no alarm will be triggered. The same behavior also applies to the upper alarm.

9. Audio alarm (optional factory setting)

In case an upper or lower alarm is triggered, 3 audible alarm signals are emitted immediately (500 ms ON / 500 ms OFF).

Thereafter:

• Every minute 1 alarm signal for maximally 168 hours (7 days).

• After 168 hours (7 days) the buzzer will stop.

• If an alarm event is confirmed (READ is pressed) while the limits are still exceeded the buzzer pauses for approx. 1 hour and then restarts beeping every 3 minutes.

• Confirmation within the alarm limits will stop the buzzer.

In case of a connection error see chapter 5.8.

10. Reading the history / Readout mode

The information of the temperature deviations can either be viewed for the past 30 days directly on the device or for

28/56/84/112 days in the generated files (PDF/ASCII).

Note : The external sensor of the Fridge-tag 2 L can remain at its location for the readout process. Please consider that there may occur a connection error after more than 10 minutes without connection between the device and the sensor.

10.1. Option 1: Read out day per day
