In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.

The value you enter is automatically rounded down to the nearest valid value.

Overview

Temperature data from the on-board temperature sensor (RTD) is always available. You
can set up an external temperature device and use external temperature data if you want
to.

Tip

Use an external device only if it is more accurate than the internal RTD.

Important

Line temperature data is used in several different measurements and calculations. It is possible to
use the internal RTD temperature in some areas and an external temperature in others. The
transmitter stores the internal RTD temperature and the external temperature separately. However,
the transmitter stores only one alternate temperature value, which may be either an external
temperature or the configured fixed value. Accordingly, if you set up polling for temperature in one
area, and digital communications in another, and configure a fixed temperature value in a third, the
fixed value will be overwritten by polling and digital communications, and polling and digital
communications will overwrite each other.

Prerequisites

If you plan to poll an external device, the primary mA output must be wired to support
HART communications.

Procedure

Choose the method to be used to supply temperature data, and perform the required
setup.
