• Log File, 1 Hour Interval
Energy (watthour) and pulse counts per hour for each channel is stored on the hour every hour.
Each data storage cycle takes 1 row, and at the maximum of 1 month data is stored in a CSV (divided with comma) format
file. The first row of the file contains the data contents descriptions and the second contains the engineering unit descriptions.

• Log File, 1 Minute Interval
Voltage, current, power, energy (watthour), and pulse counts per minute for each channel is stored.
Data transfer for the whole hour to the SD card is executed only at the same moment as for the hourly data.
Each data storage cycle takes 1 row, and at the maximum of 1 day data is stored in a CSV (divided with comma) format file.
The first row of the file contains the data contents descriptions and the second contains the engineering unit descriptions.
