Data No. Description
0 Time T + Average power P + Time T + Average voltage V + Time T + Average current I
1 Time Tp + Minimum power P + Time Tv + Minimum voltage V + Time Ti + Minimum current I
2 Time Tp + Maximum power P + Time Tv + Maximum voltage V + Time Ti + Maximum current I
* The unit of time is second. The maximum time is 5400 seconds, where the time is reset to 0.

Time T is a lapse of time between the last data communication and the one before. Tp, Tv, and Ti
are lapses of time between the time when the maximum or minimum value of power, voltage, and
current was measured, respectively, and the time when data communication to collect its statistics
occurred.
Example
To use Category B to send a command to read out “Time T + Average power P + Average
voltage V + Average current I”:

• A thin underline “_“ indicates a command. A thick underline “_“ indicates data to be read
out.
• Response data do not actually have spaces in between. Spaces are inserted in the
example above to make numbers easy to read.
• For analysis of response data, refer to Appendix, “ASCII Code Table.”
