Meriam M2110F SMART FLOW GAUGE - Manual (Page 12)

5.1 PROGRAMMABLE REGISTER LIST
All M2110F Flow Gauges have programmable registers that allow the gauge to be configured to fit the flow
measurement application. The programmable registers are numbered P0 through P10 and each register controls a
specific aspect of the gauge’s performance.
During any register editing operation the display will return to the measure mode display after one minute of keypad
activity. This will ensure that the gauge will be available for flow measurement observation even if it was
unintentionally left in the program display mode.
