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. Connect L (Live) N (Neutral) and AC Ground.
Optional DC input model requires 9-32 VDC/9 Watts. Connect to + and - terminals.
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), located on the power supply.

QUICK BENCH TEST:
In the TTFM Calibration menu set parameters to perform a bench test:
-Set Pipe OD = 1.000 inch
-Set Pipe wall = 0.25 inch
-Set Pipe material to ABS
-Press twice to exit Calibration and return to main display.
From main display press to view Status menu. Apply coupling compound to the face of transducers
and press together as indicated in the illustration below.
The Status menu should indicate Echo Confidence of 100% and a high Signal Strength (75-100% for
TTFM with standard options).

KEYPAD SYSTEM
The diagram on page 8 shows the TTFM 1.0 menu system. Arrows show the four directions to leave a
menu box. Pressing a corresponding keypad arrow will move to the next item in the direction shown.
Move the cursor (underline) under numerals and increase or decrease numerals with the and keys.
To store calibration values permanently (even through power interruptions), press the .

RUN
The main display shows the units selected from the Units/Mode menu, Flow or
Velocity rate being measured, TOTALIZER and RELAY states. The TTFM 1.0
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 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 to return to the
main display.
STATUS
Press 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 Strength Displays magnitude of signal being received by the
ultrasonic transducer.
EC Echo Confidence - displays percentage of good echoes
received.
Relays Energized relays will display as a white character on a
black background.
20mA at Displays the flow value entered in Calibration
menu for 20mA output.
