A.5 Configuring Smart Meter Using Pushbuttons, Continued

Transmitter Output Conformity and Smart Meter Configuration, continued

•If you select pressure type engineering units, you cannot set the lower or upper display limits. These values are automatically set when you select the engineering units.

•You can set only the upper display limit when the transmitter is configured for SQUARE ROOT output conformity. The lower display limit is fixed at zero (0) for a transmitter in square root mode and cannot be changed.

•You can set both the lower and upper display limits when you have selected custom engineering units (EUF) and the

transmitter output conformity is set to LINEAR.

When setting the lower and upper display limits, if you let either the lower or upper display limit setting time out (after thirty seconds), the meter will discard the newly set values and will revert to its previous settings. The meter forces you to set both limits by automatically initiating the next limit setting, either lower or upper, depending upon which limit you set first.

3. If you change the transmitter’s output conformity, you must reconfigure the smart meter as outlined in Tables A-5, A-7 and A-8.
