71M6515H Demo Board User’s Manual
System Constants Area (9):
This area consists of two entry fields to the right of the Temperature Compensation area. Entries in these
fields determine the system parameters of the Demo Board.

IMAX
VMAX
Default
208A
600V
Function
IMAX is the RMS meter current that results in 250mV peak signal at the
ADC input. This variable reflects the scaling implemented by the voltage
sensing resistors of the Demo Board.
Note: When using shunt resistors as current sensors, IMAX must be
calculated as (V ppmax = 250mV):
V pp max
IMAX =
R sh ? 2
VMAX is the RMS meter voltage that results in 250mV peak signal at the
ADC input. This variable reflects the design of the current sensing circuitry
of the Demo Board, assuming a 2000:1 current transformer.
Warning Thresholds Area (10):
This area consists of seven entry fields to the right of the Temperature Compensation area.

Function
Determines the creep threshold. For each phase, if WSUM_X and
VARSUM_X of that phase are less than the value in the CREEP field, the
contents of I 2 h, Wh, and VARh for that phase will be set to zero for the
whole accumulation interval. If all phases are below the creep threshold,
the CREEP bit in the status word is set. The default value is 6000.
Threshold for over-voltage alarms, measured in Vrms.
Threshold for over-current alarms, measured in Arms.
Determines the voltage sag threshold. The peak voltage must exceed
the voltage entered in this field at least once each SAG_CNT samples in
order to prevent a sag warning.
Values can be entered directly in Volts. The GUI will round the entered
value to the next possible value that can be represented with the
resolution used for this parameter.
Determines the sag alarm setting. Sag must persist SAG_CNT *397 μ s
before the sag alarm is generated. Allowed range is 1 to (2 15 -1). Default
is 80 (31.7ms).
Determines the voltage below which the calculation of frequency, zero
crossings and voltage phase is suppressed.
Determines the current below which the calculation of current-related
values is suppressed.
