OPERATING THE DISPLAY MODULE

• When power is applied to the display module, the power on LED will light and the black
LCD display segments will illuminate. The display(s) will indicate ow data if the ow

meter(s) is connected and there is ow in the pipe.

• The letter “R” will precede the displayed value when the display is indicating a ow rate
such as GPM. Values shown without “R” preceding the number are totals.

• For displays congured to indicate both rate and total, use the SEL button to toggle the
display between rate and total values.

• Engineering units and multipliers are shown immediately below the display as shown
above. Multiply the current reading by the mulitplier to determine the correct rate

and/or total.

• The RST button, if enabled, will reset accumulated totals to zero when pressed. ONICON
display modules are shipped with the RST button disabled. Contact ONICON if you wish
to enable this function. The display will indicate “Cnt OVEr” when the total exceeds the
maximum count.
