Synchronized demand

You can configure the demand calculations to be synchronized using an external pulse input, a command sent over communications, or the device’s internal real-time clock.

Input synchronized demand
This method allows you to synchronize the demand interval of your meter with an external digital pulse source (such as another meter’s digital output) connected to your meter's digital input. This helps synchronize your meter to the same time interval as the other meter for each demand calculation.
Command synchronized demand
This method allows you to synchronize the demand intervals of multiple meters on a communications network. For example, if a programmable logic controller (PLC) input is monitoring a pulse at the end of a demand interval on a utility revenue meter, you can program the PLC to issue a command to multiple meters whenever the utility meter starts a new demand interval. Each time the command is issued, the demand readings of each meter are calculated for the same interval.
Clock synchronized demand
This method allows you to synchronize the demand interval to the meter’s internal real-time clock. This helps you synchronize the demand to a particular time, typically on the hour (for example, at 12:00 am). If you select another time of day when the demand intervals are to be synchronized, the time must be specified in minutes from midnight. For example, to synchronize at 8:00 am, select 480 minutes.
NOTE: For these demand types, you can choose block or rolling block options. If you select a rolling block demand option, you need to specify a subinterval.
