(2) Recording with SD memory card
The measurement data is accumulated in the internal memory and output as a CSV file to an
SD memory card by pressing the SET/REC/STOP key.
The internal memory can accumulate approximately 8,500 data, output them to an SD
memory card without stopping measurement and collect the data when required
In the SD memory card, the measured data is saved in the folder having a unique name to
identify the Air Thermo Logger. Therefore, even if two or more Air Thermo Loggers are
controlled, the data of each logger can be collected with one SD memory card while the data
in each logger is normally saved in each internal memory.
Approximately 17 million data items can be recorded (can be stored for 5 years with one Air
Thermo Logger with a measurement interval of 10 seconds).
(3) Graphical display software
The data output to the SD memory card can be displayed as graphs with PC software. The
graphs can be displayed by just specifying the SD memory card drive on the PC. The data
items of different periods can be connected, and the data items collected from one or more Air
Thermo Logger can be displayed side by side.
For details, refer to " Multi Data Viewer Light Software Manual".
