BATTERY
- A built-in rechargable NiMH battery supplies power for 18 hours continuous operation when fully
charged.
- 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 5.1 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.

MESSAGE ICON
Press from the MAIN display to view error/warning messages provided by the
instrument. The Message icon will appear on the MAIN display if error messages
are being generated by the instrument. Press to return to the main display.
STATUS
Press from the MAIN 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.
20mA at Displays the flow rate set as 20mA in the Calibration
menu. Press to return to the main display.

CALIBRATION
Press the to

before each menu item and to enter. When settings are completed press to
store and return to the
Calibration menu.
*20mA at Press then or 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 or 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).
Min Vel Press and enter a minimum velocity cutoff. Forward and
reverse velocities less than
Min Vel will be forced to zero.
Pipe ID Place the highlight under the digits and then or 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 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.
