4.5.3 Using the Built-in RJ Sensor
Although accurate temperature output (reference junction compensation)
requires an external RJ sensor to be used, you can use the RJ sensor
built into the instrument.
The default setting (at shipment) is OFF.
Set the built-in RJ sensor to ON (enable) in setting mode.

The generation operating procedure is identical to that described in "4.5.1
Generating Thermocouple (TC) Signals."
For details on setting mode, refer to "7. Setting Mode."
Tip
The built-in RJ sensor measures (detects) the internal temperature of the
measurement terminals. Accuracy is affected by temperature rises due to,
for example, charging. For accurate temperature output,
use an external RJ sensor or cold junction compensator.
