NOTE
To avoid configuration errors, only select Engineering Units for XD_SCALE
and OUT_SCALE that are supported by the device. The supported units
are:
When the engineering units of the XD_SCALE are selected, this changes
the engineering units of the PRIMARY_VALUE_RANGE in the Transducer
Block to the same units.
THIS IS THE ONLY WAY TO CHANGE THE ENGINEERING UNITS IN
THE SENSOR TRANSDUCER BLOCK, PRIMARY_VALUE_RANGE
parameter.
Configuration Examples
Sensor Type: 4-wire, Pt 100
= 385.
Desired measurement process temperature in the –200 to 500 °F range.
Monitor the transmitter electronics temperature in the –40 to 185 °F range.
Transducer Block
If Host System Supports Methods:
1.
Click on Methods
2.
Choose Sensor Connections
(1)
3.
Follow on-screen instruction to setup Sensor 1 as a 4-wire, Pt 100
= 385
If Host System Does Not Support Methods:
1.
Put transducer block into OOS mode.
a. Go to MODE_BLK.TARGET
b. Choose OOS (0x80)
2.
Go to SENSOR_CONNECTION
a. Choose 4-wire (0x4)
3.
Go to SENSOR_TYPE
a. Choose PT100A385
4.
Put the transducer block back into Auto mode.

Some choices may not be available due to the current configuration of the device.
Examples:
1) Sensor 2 cannot be configured at all if Sensor 1 is set up as a 4-wire sensor
2) If Sensor 2 is configured, Sensor 1 can not be set up as a 4-wire sensor (and vise-versa)
3) When selecting a thermocouple as the sensor type, a 3- or 4-wire connection cannot be
selected.
In this situation, configure the other sensor as “Not used.” This will clear the dependencies
that are preventing the configuration of the desired sensor.
