Installing the Meter

For transmitters ordered with the LCD meter, the meter is shipped installed. 
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. 

1.

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

2. Remove the transmitter cover opposite the field terminal side. Do not 

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

3. Remove the failure mode and alarm jumpers from the electronics module 

and insert them in their new positions above and below the meter 
readout on the meter assembly.
