Voltage sag duration, V1Sag
the count of output word rate (OWR) samples utilized to determine a sag or fault event. These are integers in
the range of 0 to 8,388,607 samples. A value of zero disables the feature.
Address: 1 ( V1Sag
Default = 0
Voltage sag level, V1Sag
an input level below which a sag or fault is triggered. These are two's complement values in the range of
-1.0 ≤ value < 1.0, with the binary point to the right of the MSB. Negative values are not used.
Default = 0
The Temperature Measurement ( T
measurement. Writing a one to the LSB causes the temperature to be measured and the Temperature register
( T ) to be updated.
