3.9.3

Date

HART 5 Fast Keys
HART 7 Fast Keys
The Date command is a user-defined variable that provides a place to save the date of the last
revision of configuration information. It has no impact on the operation of the transmitter or the
HART-based communicator.
3.9.4

Descriptor

HART 5 Fast Keys
HART 7 Fast Keys
The Descriptor variable provides a longer user-defined electronic label to assist with more
specific transmitter identification than is available with tag. The descriptor may be up to 16
characters long and has no impact on the operation of the transmitter or the HART-based
communicator.
3.9.5

Message

HART 5 Fast Keys
HART 7 Fast Keys
The Message variable provides the most specific user-defined means for identifying individual
transmitters in multi-transmitter environments. It allows for 32 characters of information and is
stored with the other configuration data. The message variable has no impact on the operation
of the transmitter or the HART-based communicator.

Measurement filtering

3.10.1 50/60 Hz filter
HART 5 Fast Keys
HART 7 Fast Keys
The 50/60 Hz Filter (also known as Line Voltage Filter or AC Power Filter) command sets the
transmitter electronic filter to reject the frequency of the AC power supply in the plant. The 60
Hz or 50 Hz mode can be chosen. The factory default for this setting is 60 Hz.
Note
In high noise environments, normal mode is recommended.
