Calculating The Charges For 2 Months Ago Or Earlier; Periodically Saving Usb Output To A Pc - Mitsubishi Electric AE-200A Instruction Book

4-2. Calculating the charges for 2 months ago or earlier

CSV files can be retrieved from a USB memory on the AE-200 for periods of up to 62 days (2 months) prior to
the previous day. It is recommended that you periodically (once a month) back up CSV data in order to calculate
charges for periods earlier than that.
To calculate charges for
62 days ago or earlier,
you need to periodically
save CSV data.

*1 If CSV data (apportioned results) is retrieved from the AE-200 as shown in the figure above, charges for the period from Dec. 21 to Dec.
31 where the CSV data is missing cannot be calculated.
*2 To calculate the charge from Oct. 16 to Dec. 15 in the figure above, calculate for the period from Oct. 16 to Nov. 30 using the CSV file for
Sep. 30 to Nov. 30, and then calculate for the period from Dec. 1 to Dec. 15 using the CSV file for Oct. 20 to Dec. 20.
The total of these two output files will be the calculation result for Oct. 16 to Dec. 25.
Where a total is taken from two files for different periods (on the same AE-200), the charge cannot be calculated in a single operation.

4-2-1. Periodically saving USB output to a PC

Periodically save your data (at least once per month).
Important
• When multiple AE-200 units are used, output to a USB for each AE-200 unit.
Refer to section 3-2-2 [1] "CSV files (apportioned results) in systems where electric energy is metered
(with-metering-device method)" or 3-2-2 [2] "Systems where the electric energy is entered manually (no-
metering-device method)" for how to make a backup.
