RUN
The main display shows the units selected from the Units/Mode menu,
Flow or Velocity rate being measured, TOTALIZER and RELAY states.
The DFM 5.0 will start-up with this display and will return to this screen
after a timeout if keys are not pressed in other menus.
MESSAGE
Press Ç from the RUN display to view status of the data logger and
error/warning messages provided by the instrument. The word Message
will appear on the RUN display if error messages are being generated by
the instrument. Refer to the manual section Error/Warning Messages for a
description. Press ü to return to the main display.
STATUS
Press È from the RUN display to view instrument status. Velocity will be
displayed in ft/sec or m/sec.
Tot Displays the current totalizer reading.
Signal Cutoff Adjust the setting in percent to suppress flow readings
at zero flow when fluid swirling or pipe vibration may cause the
instrument to continue reading. Example: Signal Cutoff at 5% will force
the display and outputs to zero when signal strength drops below 5%.
Signal Strength Displays percentage of signal being received by the
ultrasonic sensor.
Sig Confidence This indicates consistent or widely varying flow rates
and helps gauge the quality of the velocity signal in the application.
Relays Energized relays will display as a white character on a black
background.
20mA at Displays the flow rate set as 20mA in the Calibration menu.
Press ü to return to the main display.
