2) There are two ways to calculate THD:
THDf (based on Fundamental):
where I
n
represents the RMS value for the n
th
harmonic and I
1
represents the RMS value of the
Fundamental harmonic.
THDr (based on RMS):

3) The Self-Read Time applies to both the Maximum Demand Log as well as the Max./Min. Log and
supports the following three options:
A zero value means that the Self-Read will take place at 00:00 of the first day of each month.
A non-zero value means that the Self-Read will take place at a specific time and day based on
the formula: Self-Read Time = (Day x 100 + Hour) where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For
example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day
of each month.
A 0xFFFF value means the automatic self-read operation is disabled and the log will be
transferred manually.
