4.1.2 Display Refresh Rate
The M2110F Flow gauge converts signal data from the differential pressure sensor at a rate of ten conversions per
second depending on the operating mode of the gauge. The display is then refreshed at a rate of approximately three
updates per second with a value that can be filtered by a user selectable time constant.
Note: All internal calculations, analog and contact outputs, and serial interface values are updated at the maximum
sampling rate.
4.1.3 Display Resolution
The differential pressure sensor range and the A/D conversion hardware in the device define the display resolution.
Note that since the Flow Gauge display is user-scaled to flow units, the full scale and resolution depends on the
calibration scaling. If a specific value will not fit on the 4½-digit display the auto-range feature will decrease the
resolution to allow the display value to fit the available digits.
4.2 KEYPAD OPERATIONS
The front panel keypad incorporates multifunction keys where the functionality will depend on the mode of
operation of the gauge.
• Measure Mode is the normal operating display mode of the gauge. This mode is always default after
power-up or reset.
• Program Mode is used to configure the gauge for operation. A PRGM indicator on the display denotes
this mode.
