Download by Year
Measured data selected with the radio button can be downloaded by year.
For measurement data with more than 1 million data items, the measurement data is divided into 1 million items.
The file size displayed on the screen is the file size before decompressing the compressed file, and the file size after decompression is 10 to 15 times the file size before decompression.
