1 WHAT YOU CAN DO WITH DATALOGGER (FEATURES)
Datalogger is a device that logs data of temperature and/or humidity and
stores this data in its memory so that you can manage or analysis it on a
computer.
• Storage of up to 8100 lines of data. ( →P.43)
Ensuring long-term measurement:
If the Datalogger is set to log data every 30 minutes, approximately 165
days.
If the Datalogger is set to log data every 90 minutes, approximately 480
days.
• Four logging options to allow for selection of the setting
that best suits your needs ( →P.43)
1. Once (default)
The Datalogger keeps logging until the memory becomes full or 8100
lines of data are collected.
2. Repeatedly (overwriting)
The Datalogger overwrites the existing data from the start once the 8100
lines of data are collected. This setting is ideal for collecting data during
a certain period.
3. Ends at… (limited amount)
The Datalogger only collects a certain amount of data (up to 8100 lines)
as specified by the user. This setting is ideal when you want to limit the
amount of data to be collected.
4. By pages (partitioning)
The Datalogger performs four different logging tasks in sequence by
storing each task's data in the four divided memory blocks. This setting is
ideal if you want to collect data from multiple sites with one Datalogger.
• Scheduled logging ( →P.51)
You can preset the time to start logging. This setting is ideal if you want to
start logging automatically.
• Real-time communications ( →P.54)
The logged data of temperature and/or humidity can be downloaded to
computers while the Datalogger is still logging.
• USB connection
USB easily offers a connectivity to your computers than the conventional RS-232C.

2 |
• Displays the approximate amount of memory currently used. ( →P.44)
Easy to determine how much more logging is possible.
• Probes can be interchangeablely used.
The sensors are fully compatible among the series models so that, in case
of probe failure, it is easy to replace by interchanging with another probe.
• 14 logging intervals ( →P.42)
The logging intervals available are in seconds (1, 2, 5, 10, 15, 30) and in
minutes (1, 2, 5, 10, 15, 30, 60, 90).
• ID on each Datalogger ( →P.40)
The ID numbers of 1 to 9 can be set for easy identification when multiple
Dataloggers are used.
• No data loss even if the batteries go dead
There is no data loss even if there is a power failure, as the logged data is
stored in the EEPROM.
• Warning display for upper/lower limit of temperature or humidity
The Alarm mark lights on the LCD if the temperature or humidity exceeds
the preset threshold. This helps to prevent damage to your product.
• Easy to use software program for data analysis
The logged data can be fully utilized by plotting in graphs and displaying
in real time. Data can also be saved in CSV format and analyzed by
commercial spreadsheet software.
