direct access to the signal terminals. An extended cover is required to
accommodate the meter.
The meter features a two-line display that accommodates five digits for
reporting the process variable on the top line, and six characters for
displaying engineering units on the bottom line

. And in addition to
units of pressure, the new LCD meter is capable of displaying flow and
volume units. The meter uses both lines to display diagnostic messages.
You can configure the meter to display the following information:
• Engineering Units
• Percent of Range
• Alternating between any two of the above
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres when the circuit
is alive.
• Before connecting a HART-based communicator in an explosive atmosphere,
make sure the instruments in the loop are installed in accordance with
