If the unit has regular hardware, RMS values are in units of squared secondary, with two bytes of
fraction. That is, each count is 1/65536 of a squared volt. If the unit is supplied with 300V hard-
ware, RMS values are in units of squared secondary, with 14 bits of fraction. That is, each count
is 1/16384 of a squared volt. Units that have 300V hardware can be identified by the appropriate
setting in the programmable settings.
For example:

• The next byte holds eight bits representing the Delta of the High Speed Input States.
These RMS values report the maximum or minimum value during a surge or sag. A given
reading is only valid in the record recorded when a surge or sag ends and only for the channel or
channels on which surges or sags ended.
High Speed Digital Input States are in the following format:
A bit value of 1 means the input changed in the last cycle. A bit value of 0 means the input did
not change.
• The next byte holds eight bits representing the Current States of the High Speed Inputs.
The Current States of the High Speed Digital Inputs are in the following format:

A bit value of 1 means the input is open. A bit value of 0 means the input is closed.
