2.1. Use
The testo 184 data loggers are used to save and read out individual
readings and measurement series. They have been specifically
designed for monitoring the transportation of products subject to
cold chain requirements.
Temperature and humidity readings are saved throughout the
entire duration of the measurement program.
Acceleration readings are monitored throughout the duration of the
measurement program and saved when the set limit value is
exceeded.
Data logger programming and measurement report output are
implemented via PDF files, no software needs to be installed.
Product versions T1 and T2 are single-use data loggers with a
time-limited service life.

For technical reasons, the display speed of liquid crystal
displays becomes slower at temperatures below 0 °C
(approx. 2 seconds at -10 °C, approx. 6 seconds at -20 °C).
This has no influence on the measuring accuracy.
For technical reasons, battery performance decreases at
lower temperatures. This has no influence on the
measuring accuracy. We recommend the use of fully
charged batteries in order to avoid a reset of the instrument
at low temperatures.

3.4. Important information and glossary
of terms
• Single-use data logger (versions T1 and T2): the data logger
has a time-limited service life, which begins from the first time
the program is started.
• Start and stop setting: the criteria for starting and stopping the
program are defined in the configuration file.
One of the criteria must be selected for starting the program.
When selecting the criterion, a time delay can be entered
(program starts x minutes after pressing the key).
Both criteria can also be selected for stopping the program. The
criterion that occurs first stops the program.
• Measuring interval: the measurement interval defines the
intervals at which readings are saved.
• Time mark: time marks can be set for documentation by
pressing the START key for 3 seconds during the
measurement, e.g. when responsibility is switched to another
institution. A maximum of 10 time marks can be set. Setting a
time mark resets the statistical values Min, Max and MKT.
• Acceleration (shock): the (positive and negative) acceleration
is measured in 3 measurement axes. Only those readings that
exceed the set limit value (maximum value per 1 second) are
stored and displayed.
The acceleration readings of the 3 measurement axes are
displayed separately on the display of the data logger.
The maximum cumulative value (peak) of the 3 measurement
axes is displayed in the PDF report.
• Report time zone: defines the time zone to which all time
specifications in the measurement report refer. Any time zone
changes during the measurement are not taken into account.
If the logger was in rSt mode and could not be
reconfigured, configuration via a copy of an XML file
may result in the time & time zone not being correct.
• Reset mode (rSt): is triggered by an interruption to the power
supply, e.g. during battery replacement. A reconfiguration of the
logger is required to resume operation. Data that has already
been recorded will not be affected.
• MKT (mean kinetic temperature): the MKT is a single calculated
temperature. MKT may be considered an isothermal storage
temperature. It simulates the non-isothermal effects of storage
temperature variations.

Tmkt = mean kinetic temperature in degrees Kelvin
∆E = activation energy (standard value: 83.144 kJ/mol)
R = universal gas constant (0.0083144 kJ/mol)
T1 = average temperature in degrees Kelvin during the first time
period
Tn = average temperature in degrees Kelvin during the nth time
period
• MKT activation energy: the default activation energy is set at
83.144 kJ/mol, as recommended in USP <1160>. If other
estimates are available as a result of studies that have been
carried out, the activation energy can be customised.
• Individual alarm: an alarm is triggered when the set limit value
is exceeded.
• Cumulative alarm (only for temperature and humidity
measurement): an alarm is not triggered when the set limit
value is first exceeded, but only once the overall duration,
during which limit values are exceeded, exceeds the set waiting
period (allowed time).
• Wall bracket (delivery includes version G1): for the
acceleration measurement, the data logger must be
permanently connected to the object to be monitored.
Mount the wall bracket using 2 screws or 2 cable ties and then
push the data logger into the wall bracket.
