LCD display meter options

HART Fast Keys
The Meter Options command allows you to customize the LCD display meter for use in your application.
The meter can be configured to display the following information:
Engineering units

Percent of range

User-configurable LCD display scale

Alternating between any two of the above

The user-configurable scale is a feature that enables you to configure the LCD display meter to a custom
scale using a HART Communicator. This feature can be used to define the decimal point position, the
upper range value, the lower range value, the engineering units, and transfer function. Refer to
meter configuration" on page 52

Detailed setup

2.10.1

Local span and zero control (local keys)

HART Fast Keys
The Local keys command allows software control over the use of the local span and zero adjustments. To
enable or disable the span and zero adjustment buttons on the transmitter, perform the Fast Key
sequence above.
Note
Disabling the local keys does not disable all transmitter configuration changes. With the local keys
disabled, changes to the transmitter configuration can still be made—including range values—using a
HART Communicator.
2.10.2

Sensor temperature output unit selection

HART Fast Keys
The Sensor Temperature Output Unit Selection command selects between Celsius and Fahrenheit units for
output of the sensor temperature. The sensor temperature output is accessible via HART only.

Diagnostics and service

The diagnostics and service functions listed here are primarily for use after installing the transmitter in
the field. The transmitter test feature is designed to verify the transmitter is operating properly, and can
be performed either on the bench or in the field. The loop test feature is designed to verify proper loop
wiring and transmitter output, and should only be performed after installing the transmitter.
