Voltage sag duration, V1Sag DUR ( V2Sag DUR ) and current fault duration, I1Fault DUR ( I2Fault DUR ) determine
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.
8.4.2 Voltage Sag and Current Fault Level (V1Sag LEVEL , V2Sag LEVEL , I1Fault LEVEL , I2Fault LEVEL )
Address: 1 ( V1Sag LEVEL ), 9 ( V2Sag LEVEL ), 5 ( I1Fault LEVEL ), 13 ( I2Fault LEVEL )

Voltage sag level, V1Sag LEVEL ( V2Sag LEVEL ) and current fault level, I1Fault LEVEL ( I2Fault LEVEL ) establish
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.

The Temperature Measurement ( T MEAS ) register is used to cycle-steal voltage channel2 for temperature
measurement. Writing a one to the LSB causes the temperature to be measured and the Temperature register
( T ) to be updated.
Refer to 6.13 Temperature Measurement on page 22 for more information.
