The process variable (PV) Damp command changes the response time of the transmitter to smooth variations in output readings caused by rapid changes in input. Determine the appropriate damping setting based on the necessary response time, signal stability, and other requirements of the of loop dynamics of your system. The default damping value is 0.4 seconds,(1) and can be reset to any of eleven pre-configured, nominal damping values between 0 and 25.6 seconds.

The Meter Options command allows you to customize the LCD meter for use in your application. You can configure the meter to display the

following information:

•Engineering Units

•Percent of Range

•User-Configurable LCD Scale

•Alternating between any two of the above

The user-configurable scale is a feature that enables you to configure the LCD meter to a custom scale using a HART Communicator. With this feature you can define the decimal point position, the upper range value, the lower range value, the engineering units, and the transfer function. Refer to “Custom Meter Configuration” in Section 6 for complete configuration information.

DIAGNOSTICS AND

SERVICE

The Local keys command allows software control over the use of the local span and zero adjustments. To enable or disable the span and zero adjustment buttons on your transmitter, perform the fast key sequence at left.

NOTE

Disabling the local keys does not disable all transmitter configuration changes. With the local keys disabled, you can still make changes to the transmitter configuration—including range values—using a HART Communicator.

The Sensor Temperature Output Unit Selection command selects between Celsius and Fahrenheit units for output of the sensor temperature. The sensor temperature output is accessible via HART only.

The diagnostics and service functions listed here are primarily for use after you install the transmitter in the field. The transmitter test feature is designed to verify that the transmitter is operating properly, and can be performed either on the bench or in the field. The loop test feature is designed to verify proper loop wiring and transmitter output, and should only be performed after you install the transmitter.

(1)Rosemount 3051ND0 default damping is 3.2 seconds. Rosemount 3051ND1, with calibra- tions below 2.5 inH2O (0,62 kPa), have damping set at 3.2 seconds.
