Default = 1.25
System Gain ( G ) is applied to all channels. By default, G = 1.25, but can be finely adjusted to compensate for
voltage reference error. It is a two's complement value in the range of -2.0 ? value ? 2.0, with the binary point to
the right of the second MSB. Values should be kept within 5% of 1.25.

Default = 0
System Time ( Time ) is measured in output word rate (OWR) samples. This is an unsigned integer in the range
of 0 to 16,777,215 samples. At 4.0 kHz, OWR it will overflow every 1 hour, 9 minutes, and 54 seconds. Time
can be used by the application to manage real-time events.

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.

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.
