Q-tag CLm
Monitoring of the entire cold chain
The Q-tag CLm can be programmed with 5 individual alarm limits from -25 °C to +50 °C. Thanks to the
break-off tab, it is clear whether the device has actually started. Immediate and easy decision-making is
ensured due to precise date and time information on the device’s display. With its long lifetime of up to 5
years, the Q-tag CLm is ideal for monitoring the entire cold chain.
• Individual alarms programmed to customer specifications
• Displays minimum and maximum temperature extremes
• Cumulative duration of the overrun for each alarm limit

4.3. Activation of the Q-tag CLm
Please always verify the expiry date prior to using any device (see Chapter Expiry Code Explanation).
The device is activated by breaking off its green start tab.
The active recording is shown by
OK symbol and the flashing dot on the LCD.
Page 7 of 19

User Manual Q-tag CLm - 1
4.4. Start delay time (optional)
If a start delay has been factory preset, the Q-tag CLm starts recording the temperature after the
completion of the start delay time.
The delay is displayed by the flashing “OFF” indicator.
Note: To avoid accidental deactivation of the device, the stop function is locked during the start delay
time.

4.5. Temperature recording
Placing the Q-tag CLm
The activated monitor must be placed immediately in its predetermined location. It is recommended to
place the device as close to the supervised goods as possible. This is an important prerequisite to
ensure the temperatures observed by the device are as close to the product temperature as possible.
Note: It is recommended to “precondition” the device for about 30 minutes to the desired mean
temperature before use, especially if no start delay time has been programmed. This is to insure against
false readings during start up.

4.6. Display indication during temperature
recording
Display examples of temperature recording:
OK
Display
A
(OK symbol) is indicated during normal
operation as long as no alarms have been
recorded.
ALARM
Display
This
(OK symbol) will be replaced by
(Alarm symbol) as soon as any alarm has been
triggered. Additional arrows are shown in the
left display area to indicate which limit has been
violated.

User Manual Q-tag CLm - 1
4.7. End of temperature recording / Stop
Mode
The Q-tag CLm may be stopped if the recording shall be finished, e.g. if a shipment has reached its final
destination. To do so, the STOP-button shall be pressed for at least 2 seconds.
The display indicates “OFF” and the flashing dot disappears.
All other indicators such as
(OK symbol) or
(Alarm symbol) and individual alarm arrows remain
stable for at least 3 months.
Display recording has been stopped: Example shows OK display

4.8. Gathering information after activation of
the device or in Stop Mode
Important note for reading information from activated devices:
To avoid misreading the Q-tag CLm interrupts its recording if and as soon as the INFO-button is pressed
(e.g. caused by hand temperature). Reading and recording will automatically resume after 14 minutes
without any button pressing.
The chart below explains the information indicated on the LCD screen upon successive INFO-button
pressing after activation or in STOP Mode:

6. Explanation of terms
Sleep Mode / State of delivery
This is the state of delivery of the device. It is the lowest current consumption state of the Q-tag CLm.
The device is not activated and no data is recorded. (see also point: State of delivery / Sleep Mode).
Measurement Mode / Recording of temperature
After breaking the green start tab, the device starts recording and analyzing the temperature. (see this
chapter).
Start delay time (optional)
The start delay is an optional functionality. If a start delay has been factory preset, the Q-tag CLm starts
recording the temperature after the completion of the start delay time. (For more information see also
point: start delay, optional).
End of temperature recording / Stop Mode
No more measurements are taken after pressing the STOP-button for more than 2 seconds. (For more
information see also point: End of temperature recording / Stop Mode).
Single Event Alarm
These alarms are triggered if the corresponding temperature limit has been violated for longer than the
allowed time in one go.
Cumulative Alarm
These alarms are triggered if the corresponding temperature limit has been violated for longer than the
allowed total time (all violations summed up).
Total duration in measurement range
This is the summarized time (single or cumulative) the temperature was recorded in an individual alarm
range, e.g. in single event high.
Running indicator
The dot on the display flashes as long as the device remains in Sleep Mode or is activated. It will
disappear when the device is deactivated by pressing the STOP-button for more than 2 seconds.
Time Expired Indicator (optional)
A maximum allowed recording time can be factory preset upon customer requirements. If the device is
Page 15 of 19

not manually deactivated by its STOP-button before the preset recording time has been exceeded, the
violation will be shown on the display by indicating “TIME EXP” and a
(ALARM symbol).
Display shows:
Time Expired, device has been stopped, with additional alarms.
