Procedure
1. Choose the method to be used to supply temperature data, and perform the required setup.
Method Description Setup
Internal RTD
temperature
data
Temperature data from the on-
board temperature sensor
(RTD) is used.
a. Choose Configure > Manual Setup > Measurements >
Optional Setup > External Pressure/Temperature >
Temperature.
b. Set External Temperature to Disable.
Polling The meter polls an external
device for temperature data.
This data will be available in
addition to the internal RTD
temperature data.
a. Choose Configure > Manual Setup > Measurements >
Optional Setup > External Pressure/Temperature >
Temperature.
b. Set External Temperature to Enable.
c. Choose Configure > Manual Setup > Measurements >
Optional Setup > External Pressure/Temperature >
External Polling.
d. Set Poll Control to Poll as Primary or Poll as Secondary.
Option Description
Poll as Primary No other HART masters will be on the
network. The Field Communicator is
not a HART master.
Poll as Secondary Other HART masters will be on the
network. The Field Communicator is
not a HART master.
e. Choose an unused polling slot.
f. Set External Device Tag to the HART tag of the external
temperature device.
g. Set Polled Variable to Temperature.
mA Input
An external device sends
temperature data to the meter
via the mA Input. This data will
be available in addition to the
internal temperature data.
a. Choose Configure > Manual Setup > Inputs/Outputs >
Channel D.
b. Set Assignment to mA Input.
c. Choose mA Input > mA Input Settings.
d. Set Var Assignment to External Temperature.
e. Set Upper Range Value and Lower Range Value
appropriately.
f. Set Damping appropriately.
