Output

This function block allows the user to determine the range and the units in which the sensor will measure the sensor input. Range and span limits are dictated by a transmitter's sensor.

Also included is a digital filter for removing process and sensor noise.

A.2 OPERATOR DISPLAY BLOCK

Process Variable Units

4 Character ASCII

Process Variable Range Lo

-19999 to 19999

Process Variable Range Hi

-19999 to 19999

Auto Rerange

Auto Reranging

Use this function block to set up Process Variable Ranges and Units to improve the understanding of the Measured Variable. The Process Variable differs from the Measured Variable. As stated in the previous function block description, the Measured Variable in actual physical units such as ohms, and the Process Variable can be shown in units that represent the actual process parameter being measured such as Temperature (deg C). The output display code determines which variable will be displayed on the digital meter. There are three options for the output display code:

1.Measured Variable - When measured variable is selected, the input will be displayed in measured variable units.

2.Percent - When percent is selected, the input will be displayed as 0-100% of the process variable range.
