NOTE:
Actual content of the OLED screen may vary depending on
the model and device configuration.
The main DPM flow meter screen shows current instrument Pressure, Temperature,
Mass Flow, and Totalizer Volume readings in previously selected units of measure.
NOTE:
5 seconds after the initial powering of the DPM flow meter,
the status LED will emit a constant GREEN light (normal operation,
ready to measure).

If a flow of more than 133% the nominal maximum flow rate of the Mass Flow
Meter is taking place (displayed mass flow reading is flashing), a condition
known as "swamping" may occur. Readings of a "swamped" meter cannot be
assumed to be either accurate or linear. Flow must be restored to below 133%
of maximum meter range. Once flow rates are lowered to within calibrated
range, the swamping condition will end.
