2 Specifications 2 Specifications 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.

3 Product description - 3.4. Hibernation mode is activated. 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.
4 Using the product Calculation: ∆ / ∆ / • • • • ∆ / ∆ / 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>.
4 Using the product 4. Make changes to the configuration. Please note: • The type of instrument used must be set correctly. • Existing configuration data can be imported by clicking on the Import button. The configuration data to be imported must be available in XML data format. • When using the Configuration Assistant, some functions are predefined or filled in automatically. Expert Mode must be enabled in order to use and manually set all instrument functions. 5.
4 Using the product Changing the logo for the measurement data report A logo is inserted in the measurement data report. This can be customised. The logo must be available in JPEG data format, the file size should not exceed 5 kB and the file name must be Logo.jpg. > Create a logo that meets the above criteria and copy it to the data logger. Configuring the data logger using Testo PC software Alternatively, the data logger can also be configured using testo Comfort Software Professional (version 4.
4 Using the product • • - 4.3. Button Stop: hold down the STOP key for > 3 seconds. Time Stop: the measurement stops automatically once the configured time has been reached. The logger switches to End mode, the Mode status LED flashes red. Reading out data Displaying a measurement data report Adobe Reader software (version 5 or later) or compatible software is required to display PDF/A files. 1. Connect the data logger to a Windows PC via the USB port.
5 Maintaining the product 5 Maintaining the product 5.1. Changing the batteries It is not possible to change the batteries for instrument types T1 and T2 (single-use data loggers). A battery replacement stops a measurement that is currently running. However, stored measurement data are preserved. An interruption of the power supply leads to the testo 184 data logger's time settings being reset.
6 Tips and assistance Do not use any aggressive cleaning agents or solvents! Weak household cleaning agents or soap suds can be used. 6 Tips and assistance Questions and answers Question Possible causes/solution E0x is displayed An error has occurred. (instruments with display), • E01: Configuration unsuccessful / all status LEDs are flashing PDF file faulty. red • E02, E03, E04 or E05: sensor faulty. • E06: maximum number of time marks set, new time mark cannot be set.
6 Tips and assistance Question Possible causes/solution Different time or time zone > The testo 184 data logger has not been configured after a battery in the report replacement. Repeat the configuration to restore the correct time settings. > Check whether the PC which was used for the configuration has the correct time settings. 18 No measurement protocol was created. > Please check whether the data logger is in record/end mode. > Please reconnect the data logger to the PC.
6 Tips and assistance Question Possible causes/solution The humidity value measured is out of tolerance. a b c Was the t99 response time achieved? Was the H1/G1 data logger stored for longer than 60 hours at a relative humidity of more than 80% without an airtight bag? Was the H1/G1 data logger used for longer than 60 hours at a relative humidity of more than 80%? Solution for points b and c: > Store the device for 12 hours at 50°C and a relative humidity of less than 20%.
