Resetting minimum and maximum values for phase-specific measurement
You can also reset the minimum and maximum values on a phase-specific basis using the
output data.
Follow the procedure for "Resetting minimum and maximum values for all 3 phases" as
applicable.
1. Select the categories of minimum and maximum value that you want to reset on a phase-
specific basis.
– In byte 7, set the bits for the category of minimum and maximum values in phase 1.
– In byte 9, set the bits for the category of minimum and maximum values in phase 2.
– In byte 11, set the bits for the category of minimum and maximum values in phase 3.
2. Set the reset bit (bit 0 and bit 1) for minimum or maximum values.
– in byte 6 for phase 1
– in byte 8 for phase 2
– in byte 10 for phase 3
If there is an edge change of the phase-specific reset bits from 0 to 1, the module resets the
minimum or maximum values for the given phase.
Procedure for module version with 2 bytes of output data
If you use the module version with 2 bytes of output data, you always reset
the minimum
and maximum values simultaneously.
Set the reset bit (Bit 0 or Bit 1) in Control byte 1 from 0 to 1 through an edge change.
