Temperature (channel 1 and 2)
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 α = 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. Select Methods.
2. Select Sensor Connections
3. Follow on-screen instruction to setup sensor 1 as a 4-wire, Pt 100 α = 385.
If host system does not support methods:
1. Put transducer block into OOS mode.
2. Go to SENSOR_CONNECTION.
3. Go to SENSOR_TYPE.
(2) Some choices may not be available due to the current configuration of the device.
Examples:
a) Sensor 2 cannot be configured at all if sensor 1 is set up as a 4-wire sensor.
b) If sensor 2 is configured, Sensor 1 can not be set up as a 4-wire sensor (and vise-versa).
c) 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.
