MEASUREMENT
Zero point suppression level as a percentage of the primary
rated current of the external current transformer:
The minimum current measurement is used for zero point
suppression so that zero is displayed below this limit.

POWER DEMAND
SUBPERIOD
Period for calculating the load profile data according to the
"fixed block" or "rolling block" method.
SENTRON PAC4200 supports the fixed block method as a
special case of the rolling block method. The most important
distinguishing feature is the number of subperiods.
The length of the demand period is defined as the product of
the length of a subperiod and the number of subperiods.
Length
demand_period
= n * length
subperiod
; n = number of
subperiods
SUBPERIOD TIME
Length of the subperiods:
Range: 1 ,2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 min
Default value: 15 min
