Installing the meter on an existing Rosemount 3051N transmitter requires a
small instrument screwdriver and the meter kit (when the kit is made available
by Rosemount Nuclear Instruments, Inc.).
To maintain the Rosemount 3051N qualification status, any piece parts for the
Rosemount 3051N (if available) must be supplied by RNII.
The meter kit includes:
• one LCD meter assembly
• one extended cover with O-ring installed
• two nylon standoffs
• two captive screws
• one ten-pin interconnection header
Use the following procedure and Figure 6-1 to install the LCD meter.

the transmitter is installed in a loop, THEN secure the loop and
disconnect power.

remove the instrument covers in explosive environments when the circuit
is alive.

and insert them in their new positions above and below the meter
