Option Setup
Polling for tempera-
ture
a. Ensure that the primary mA output has been wired to support
HART polling.
b.
Choose Online > Configure > Manual Setup > Measurements > External
Pressure/Temperature > Temperature.
c. Enable External Temperature.
d. Choose Online > Configure > Manual Setup > Measurements > External
Pressure/Temperature > External Polling.
e. Set Poll Control to Poll As Primary Host or Poll as Secondary Host.
f. Choose an unused polling slot.
g. Set External Tag to the HART tag of the external temperature de-
vice.
h. Set Polled Variable to Temperature.
Tip
• Poll as Primary: No other HART masters will be on the network.
• Poll as Secondary: Other HART masters will be on the network.
The Field Communicator is not a HART master.
A value written by
digital communica-
tions
a. Choose Online > Configure > Manual Setup > Measurements > External
Pressure/Temperature > Temperature.
b.
Enable External Temperature.
c. Perform the necessary host programming and communications
setup to write temperature data to the transmitter at appropri-
ate intervals.
Note
If the Weights & Measures application is implemented and the trans-
mitter is secured, digital communications cannot be used to write
temperature data to the transmitter.

Configuration and set Active Matrix to the matrix to be used for measurement.
Concentration process variables are now available on the transmitter. You can view and
report them in the same way that you view and report other process variables.
4.8.4 Standard matrices for the concentration measurement
application
The standard concentration matrices available from Micro Motion are applicable for a
variety of process fluids.
See Table 4-14 for a list of the standard concentration matrices available from
Micro Motion, along with the density and temperature measurement units used in
calculation, and the unit used to report concentration data.
