3.2 Mechanical Installation

Use gaskets, if required, that are suitable for the process connection and resistant to the

media.

Before starting operation, check the process connection carefully for leaks under pressure.

You can use the device in any mounting position. Normally the transmitter is adjusted for a

vertical mounting position. A different mounting position in combination with a small nomi-

nal range might cause a zero point offset. In this case a zero point adjustment might be

necessary.

3.3 Mount / dismount display

6 User Manual

The device can be configured via the display module as well as the HART protocol. The

following pages describe operation and configuration of the device using the display mod-

ule.

An overview of the menue structure can be found on the last page of this document.

6.1 Basics of the Operating Concept

The display module consists of a dot-matrix

display with 80x128 pixels as well as a

4-button control panel.

The four buttons below the display allow an

intuitive operation of the device. The gen-

eral functionality of the buttons is identical in

all operating modes.
