If the device has a display and you want to configure it to something other
than standard default, which is Engineering units & %, go to step 7.
Scale Display
7. After the transmitter is installed you can scale the display to match the
DCS or PLC as required. As an example, in Figure 4-8 on page 4-10
if the required display should be 0 to 81 inH
2
O, this can be done
using a HART field communicator. See the following steps for the
3051S or the 3051C. Often 0 to 100% is sufficient.
NOTE
Depending on the HART device (Hand held/ AMS) DD the following steps
may be slightly different.
NOTE
In both cases with the transmitter ranged -112.08 to -31.08 inH
2
O, the display
will show 0 inH
2
O at (4 mA) and 81.00 inH
2
O at (20 mA).
For the Rosemount 3051S , in the HART
menu tree, go to the Scaled variable
Config (under guided set up). Follow the
steps below. Bold text indicates entered
value.
For the Rosemount 3051C , in the
HART communicator, go to Configure
Display and follow the following steps:
1. Enter SV unit:
