A Transmitter
For additional information, refer to the operating instructions included with the handheld
terminal.
If the transmitter has been configured in the factory according to customer specifications for the
measuring point, all you have to do is mount the transmitter as prescribed (to correct potential
zero shifts, refer to the section "Correcting the zero shift"), and switch it on. The measuring point
will now be ready for use.
If the transmitter is equipped with an LCD indicator, the current pressure/absolute pressure is
displayed in % (factory setting, unless otherwise specified).
If, however, you wish to make changes to the configuration, a handheld terminal or - preferably -
a graphical user interface (DTM) is required. This DTM tool renders the device fully
configurable. It supports both the HART protocol and PROFIBUS PA fieldbus protocol, and can
be run on a PC or laptop, or as part of an automation system. Where FOUNDATION Fieldbus is
concerned, the device description (DD), which can be loaded onto various configuration tools, is
required for configuration purposes.
Refer to the installation manual provided with the software for the steps required to install the
operating tool. The most important parameters can be set via the path "Configure_Pressure
Measurement".
The program offers the option of configuring, polling, and testing the transmitter. In addition,
offline configuration can be performed by means of an internal database. Each configuration
step is subject to a plausibility check. You can call up context-sensitive help at any time by
pressing the "F1" key.
Immediately after you have received the transmitter or before you change the configuration, we
recommend that you save the existing configuration data to a separate data storage medium,
via the path "File_Save".
