- Display brightness is adjustable to conserve power.
- State of charge is shown for normal use, sleep mode and charging.
- When switched OFF with the AC power module connected the flashing battery indicates charging,
solid battery shows fully charged.
- The PDFM 5.0 will switch off automatically when the battery is fully discharged.
- Full charge requires approximately 6 hours charging.
- Sleep mode extends battery life for long term data logging. Maximum log time is 18 days at 5 minute
sample rate.

RUN
The main display shows the units selected from the Units/Mode menu,
Flow or Velocity rate being measured, TOTALIZER. The PDFM 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. 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.
20mA at Displays the flow rate set as 20mA in the Calibration menu.
Press ü to return to the main display.

24 HR LOG
Press Å from the RUN display to view a formatted flow report from
instruments with a built-in data logger. Press È to 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 ü to 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 Æ key to get to Password. Factory
default password is 0000 and if it has not been changed press the ü to
proceed to the Menu Selections screen.
If a password is required, press Æ to place the cursor under the first digit
and È or Ç to set the number, then Æ to the second digit, etc. Press Æ or
ü to proceed to the Menu Selections screen.
A new password can be stored by going to Special Functions/New
Password.

UNITS/MODE
From >Mode press the Æ and then the Ç or È to select Flow or
Velocity. Flow mode displays the flow rate in engineering units (e.g.
gpm, litres/sec, etc.) Press the ü to store your selection then the È to the
next menu item and Æ to enter.
From >Linear press the Æ key and then the Ç or È to select your units
of measurement. Press the ü to store your selection.
Press the È key to move the > symbol to each subsequent menu item and
the ü to save your selections.
Note: the volume selection "bbl" denotes U.S. oil barrel.
Press Å or ü to return to the Menu Selections screen.

CALIBRATION
Press the È to >Calibration and Æ to enter. Use È or Ç to position
> before each menu item and Æ to enter. When settings are completed
press ü to store and return to the Calibration menu
*20mA at Press Æ then È or Ç to change the numbers and decimal
point. Use this menu to set the corresponding flow rate that will be
represented by 20mA analog output. If maximum flow is unknown, enter
an estimated flow rate and observe actual flow to determine the correct
maximum value. Any velocity or flow rate up to +40 ft/sec (12.2 m/sec)
may be selected.
*4mA at Press È or Ç to set the flow rate corresponding to 4mA analog
output. This setting may be left at zero flow (or velocity or can be raised
to any value less than the 20mA setting, or lowered to any velocity or
corresponding flow rate down to -40 ft/sec (-12.2 m/sec).
Pipe ID Place the cursor under the digits and then È or Ç to change the
numbers and decimal point. Pipe ID should be entered as the exact
inside diameter of the pipe where the sensor is mounted. Refer to the Pipe
Charts Appendix in this manual for inside diameter of common pipe types
and sizes.
Damping - Increase damping to stabilize readings under turbulent flow
conditions. Decrease for fast response to small changes in flow. Damping
is shown in percentage (maximum is 99%). Factory default is 20%.
Press ü from the Units/Mode display to return to Menu Selections.
*Note 4-20mA circuitry is only powered by the AC power module.
To conserve power this output is not active in battery power mode.
