HART
Transparency
The meter does not interfere with existing
HART communications; it displays the 4-20
mA primary variable and it allows the
HART communications to pass through
without interruption.
The meter is not affected if a HART
communicator is connected to the loop.
The meter does not display secondary
HART variables.
