3.1 LIBERO CE
LIBERO CE is a multi-level and multi-use PDF Logger with USB and Bluetooth®
interface for external Pt100 probe and the ideal PDF Logger to simplify storage
and shipment process for products with known stability data.
It covers a wide measurement range from -200 °C to +400 °C and monitors
temperature of cell and drug deliveries with cryogenic containers, dry ice or
other applications using an external Pt100 probe.
Basically it can be used in all cases where the logger is to be mounted outside,
also for equipment, e.g. refrigerators. For easy mounting, a stainless steel
bracket can be ordered as an option.
Supporting up to eight temperature alarm zones, MKT and duration as alarm
criteria –LIBERO CE allows you to create temperature profiles for individual
products. In addition, you have the option to switch the alarming function off
and on again if alarming criteria is required. This can be useful in cases where a
transportation box has been cleaned, or liquid nitrogen has been refilled in a
cryogenic container.
LIBERO CE is reconfigurable and reusable for up to 3 years (depending on
usage of Bluetooth® interface). The external Pt100 probe and M8 connector
enables reliable, superior temperature data transfer to the data logger. Up to
75’500 temperature values can be stored on the data logger.
Release products with confidence based on the OK or ALARM status on the
display, the PDF report can be easily downloaded via the PC's USB interface or
read out to a smart device via the LIBERO Cx BLE app (available for iOS and
Android), thanks to the logger's Bluetooth® interface. The app can be used to
start or stop the logger without having to remove it from your equipment or
consignment.

4Devices - LIBERO CE CL CH
4.1 Functionality and Modes
Unless otherwise noted the following information applies equally to all three LIBERO Cx models.
After configuration of the logger measured values for temperature and relative humidity (LIBERO CH
only) are recorded, stored and evaluated with regard to the defined alarm criteria. The display shows
the current mode.
In configuration mode the device can be configured using the free liberoCONFIG software, this is shown
on the display as follows:
or
After configuration, the logger is ready to start recording, this is indicated in the display accordingly.
In this start mode the configuration of the device can be changed again if required. When plugged into
the USB port of a PC, the device is automatically recognized by the liberoCONFIG software and set to
"ConF"-mode without the need to press any keys.
The logger can be started by pressing and holding (3 seconds) the "Start/ON" key, the display shows the
current measured value and the flashing "Run" symbol.
If a temperature- or time-dependent delayed alarm activation has been configured a corresponding
note appears in the display after the device is started:
- Temperature-based delay: - Time-based delay:
The delay until the configured temperature The display shows the remaining time in
threshold is reached is indicated by "dELAY". The minutes before the device automatically
device then automatically switches to alarm activated switches to alarm activated measuring mode
measuring mode (see below). (see below).
(Countdown to zero takes place in measuring interval steps,
e.g. measuring interval = 10 min. >> recounting 60 - 50 - 40 - …)

1000475V01E DOC_Operation Manual LIBERO Cx BLE.docx | Page 8 / 34
Depending on the device’s configuration we can distinguish between the following two types of
measurement mode:
- Measurement mode without "Alarming ON/OFF" function:
Display of current temperature measured value (in the lower section of the display), the alarm status (in
the upper right section of the display) and the flashing measurement mode- / "Run"- indicator (top left
on the display).
LIBERO CH alternatively displays the humidity value after briefly pressing the "Stop/OFF" key. Press the
key again briefly to display the temperature value again.
- Measurement mode with "Alarming ON/OFF" function:
Display of current temperature measured value (in the lower section of the display), the alarm status (in
the upper right section of the display), the flashing measurement mode- / "Run"- indicator (top left on
the display) and the status "Alarming ON" (top center section of the display), which indicates that the
measured values are evaluated according to set alarm criteria.
LIBERO CH alternatively displays the humidity value after briefly pressing the "Stop/OFF" key. Press the
key again briefly to display the temperature value again.
Users who wish to take advantage of pausing the alarm (e.g. when refilling or cleaning) can do so by
pressing and holding (3 seconds) the "Stop/Alarming OFF" button in measurement mode.
In this case the note "AL on" appears in the lower half of the display every 2 seconds alternating with
the currently measured value, to inform the user that the alarm is suspended and can or should be
reactivated. This is done very simply by pressing and holding (3 seconds) the "Start/ON" button.
From measuring mode without configured function "Alarming ON/OFF" or from measuring mode with
status "Alarming OFF", the device can be stopped by pressing and holding (3 seconds) the "Stop/OFF"
button.

1000475V01E DOC_Operation Manual LIBERO Cx BLE.docx | Page 9 / 34
Two different display states are possible in stop mode:
Immediately after stopping the logger "Make PdF" appears on the display. This message ensures that
the user does not forget to read out the device and it disappears after the PDF report has been created
by plugging the device into the USB port of a computer.
After the device has been read out, "Stop" appears on the display. In this situation, the device can either
be restarted (based on the existing configuration) or reconfigured via liberoCONFIG software by
connecting it to a USB port on the computer without pressing any more buttons.

4.2 Logger service life / battery runtime
PDF Loggers LIBERO Cx BLE are designed for an extended usage period of up to 3 years. The actual
service life is reduced by operation at low temperatures (especially below 0 °C) and frequent use of
Bluetooth® connection to a smart device.
Shortening the period of use
Should the period of use for the devices be deliberately limited to 12 or 24 months, the user can order
this option from ELPRO as a factory-made configuration.
Note: This factory-configured expiry date cannot be reset by the user by reconfiguring with
liberoCONFIG.
Reaching the end date is indicated in the display by the message "EoL" (End-of-Life), the logger can no
longer be used.
Reduction of battery runtime
Depending on the Bluetooth® mode selected, there is a reduction in the service life due to increased
energy consumption, according to the following table:
Bluetooth® mode
Runtime
BLE permanently OFF
36 months
BLE temporarily ON (by pressing "Start" button)
24 months
BLE permanently ON
14 months
Conditions: Measuring interval: 10 minutes, operating temperature range,
Customer usage behavior: average assumptions.
Battery warning
If the capacity of the battery has reached a minimum level, this is indicated by a warning symbol in the
logger display.
From this moment on, the logger should no longer be used and can therefore no longer be started. If
the logger is in "Run" mode, a remaining period of use of approx. 8-10 days can be assumed.

6Configuration
liberoCONFIG is the free software to configure LIBERO PDF data loggers. It allows users to define all
necessary configuration parameters and to save them as profiles. A profile contains all settings for the
monitoring task and is summarized in the PDF report generated by the logger or in a special
configuration report that can be generated in liberoCONFIG.
The configuration of a single LIBERO Cx is done with liberoCONFIG.
With SmartStart Pack & Go a profile can be assigned to a larger number of LIBEROs quickly and safely.
SmartStart Pack & Go .exe files can be used on any PC without installation and without special drivers.

described.

1000475V01E DOC_Operation Manual LIBERO Cx BLE.docx | Page 20 / 34
Logging
"Loop" has been added as an additional recording mode, since LIBERO CE/CL/CH loggers are for
multiple use.
NOTE: When memory capacity of the logger is reached, newly measured values continuously
overwrite the oldest stored values!
For temperature- or time-delayed alarm activation the option has been added that such activation is
also possible in case the alarm is subsequently switched on again after a phase of "alarming OFF" mode.
