• DEFAULT MESSAGE TIME: Up to 10 default messages can be selected to scan
sequentially when the PQMII is left unattended. If no keys are pressed for the interval
defined by the
DEFAULT MESSAGE TIME setting, then the currently displayed message is
automatically overwritten by the first default message. After 3 seconds, the next
default message in the sequence is displayed. Alarm messages will always override
the default message display. Note that any setpoint or measured value can be
selected as a default message.
See 3.4: Default Messages for details on default message operation and programming.
• DISPLAY FILTER CONSTANT: Display filtering may be required in applications where
large fluctuations in current and/or voltage are normally present. This setpoint allows
the user to enter the PQMII filter constant to average all metered values. If the
DISPLAY
FILTER CONSTANT setpoint is set to 1, the PQMII updates the displayed metered values
approximately every 400 ms. Therefore, the display updating equals
DISPLAY FILTER
CONSTANT × 400 ms.
