) and current fault duration, I1Fault

DUR

(I2Fault

) 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.

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.

8.5.1 Temperature Measurement (T

MEAS

)

Address: 26

Default = 0

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.
