Using the Display
B.3 Using the optical switches
The
Scroll and Select optical switches are used to navigate the display menus. To activate an optical
switch, touch the lens in front of the optical switch or move your finger over the optical switch close
to the lens. There is an optical switch indicator between the optical switches. When an optical switch
is activated, the optical switch indicator is a solid red.
Attempting to activate an optical switch by inserting an object into the opening can damage the
equipment. Do not insert an object into the openings. Use your fingers to activate the optical switches.
B.4 Using the display
The display can be used to view process variable data or to access the transmitter menus for
configuration or maintenance.
B.4.1 Display language
The display can be configured for the following languages:
• English
•French
• Spanish
•German
Due to software and hardware restrictions, some English words and terms may appear in the
non-English display menus. For a list of the codes and abbreviations used on the display, see
Table B-1.
For information on configuring the display language, see Section 4.16.5.
In this manual, English is used as the display language.
B.4.2 Viewing process variables
In ordinary use, the
Process variable line on the LCD panel shows the configured display variables,
and the
Units of measure line shows the measurement unit for that process variable.
• See Section 4.16.5 for information on configuring the display variables.
• See Table B-1 for information on the codes and abbreviations used for display variables.
If more than one line is required to describe the display variable, the
Units of measure line alternates
between the measurement unit and the additional description. For example, if the LCD panel is
displaying a mass inventory value, the
Units of measure line alternates between the measurement
unit (for example,
G) and the name of the inventory (for example, MASSI).
Auto Scroll may or may not be enabled:
• If Auto Scroll is enabled, each configured display variable will be shown for the number of
seconds specified for Scroll Rate.
• Whether Auto Scroll is enabled or not, the operator can manually scroll through the configured
display variables by activating
Scroll.
For more information on using the display to manage totalizers and inventories, see Section 5.8.
