Description

Reset:

-Write 30078 (0x757E) to clear all energy accumulators to 0 (all).

-Write 21211 (0x52DB) to begin new demand sub-interval calculation cycle. Takes effect at the end of the next 1 second calculation cycle. Write no more frequently than every 10 seconds.

-Write 21212 (0x52DC) to reset max. demand values to present demand values. Takes effect at the end of the next 1 second calculation cycle. Write no more frequently than every 10 seconds.

-Write 16640 (0x4100) to reset logging.

-Write 16498 (0x4072) to clear pulse counts to zero.

-Read (returns 0).

PT Ratio: The meter scales this value by 100 (i.e. entering 200 yields a potential transformer ratio of 2:1). The default is 100 (1.00:1), which is with no PT attached. Set this value before setting the system voltage (below).

System Voltage: This voltage is line to line, unless in system type 10 (register 130), which is line to neutral. The meter uses this value to calculate the full scale power for the pulse configuration (below), and as full scale for phase loss (register 142). The meter will refuse voltages that are outside the range of 82-660 volts when divided by the PT Ratio (above).

Theoretical Maximum System Power – This read only register is the theoretical maximum power the meter expects to see on a service. It is calculated by the meter from the system type (register 130), CT size (register 131), and system voltage (register 134) and is updated whenever the user changes any of these parameters. It is used to determine the maximum power the pulse outputs can keep up with. This integer register has the same scale as other integer power registers (see register 140 for power scaling).
