DISPLAY FILTER CONSTANT:
Display filtering may be required in applications where
large fluctuations in currents and/or voltages are normally present. This setpoint
allows the user to enter the PQM filter constant to average all metered values. If the
DISPLAY FILTER CONSTANT
setpoint is set to
1
, the PQM updates the displayed
metered values approximately every 400 ms. Therefore, the display updating equals
DISPLAY FILTER CONSTANT
×
400 ms.
