CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz . No
adjustments are necessary for voltages within this range.
Optional DC input model requires 9-32 VDC/7 Watts. Connect to + and −terminals. Connect L (Live)
N (Neutral) and AC Ground.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay
connection wires must have conduit entry to the instrument enclosure. Installation requires a switch,
overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked
as the disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.
Note: User replaceable fuse is 2 Amp 250V (T2AL250V).

OPTIONAL FEATURES
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 Çfrom 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 üto return to the main display.
STATUS
Press Èfrom 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 üto return to the main display.

24 HR LOG (Data Logging option only)
Press Åfrom the RUN display to view a formatted flow report from
instruments with a built-in data logger. Press Èto scroll down one day or
repeatedly to scroll to a specific date. Up to 365 days can be stored.
Newest date will overwrite the oldest. Press üto return to the main
display.
PASSWORD
The password (a number from 0000 to 9999) prevents unauthorized access
to the Calibration menu.
From the Run display press the Ækey to get to Password. Factory
default password is 0000 and if it has not been changed press the üto
proceed to the Menu Selections screen.
If a password is required, press Æto place the cursor under the first digit
