INSTALLATION
OPTIONS
Analog Displays Option Codes M1, M2, and M6 provide local indication of the transmitter
output in a variety of scaling configurations with an indicator accuracy of ±2
percent. The plug-in mounting configuration allows for simple installation and
removal of the analog displays. The meter scaling options are shown below.
M1 Linear analog display, 0–100% scale
M2 Square-root analog display, 0–100% flow scale
M6 Square-root analog display, 0–
10√ scale
LCD Displays The LCD Display Option Codes, M4 and M7–M9, provide a highly accurate
local display of the process variable. A variety of scaling configurations are
available and listed as follows:
M4 Linear LCD Display, 0 to 100%
M7 Special scale LCD Display (specify range, mode, and
engineering units)
M8 Square-root LCD Display, 0 to 100%
M9 Square-root LCD Display, 0 to 10%
LCD Display Configuration
The Rosemount LCD Display has four digits and plugs directly into the
Rosemount 1151 Smart Pressure Transmitter to provide a highly accurate
digital display of the process variable. This manual explains the configuration
and assembly of the LCD Display and includes the applicable functional,
performance, and physical specifications. This meter adds no voltage drop in
the 4–20 mA current loop when connected directly across the transmitter test
terminals.
The LCD Display may be configured to meet specific requirements by using
the left and right calibration buttons located on the meter face as shown in
Figure 2-12. The LCD Display cannot be configured for reverse flow because
the 20 mA value must always be greater than the 4 mA value. The analog bar
graph is also shown in Figure 2-12. The 20-segment bar graph is factory
calibrated and represents 4–20 mA directly.
