– Tc type selection
Next page helps the operator to select: the engineering unit (°C - °F - K) and the type of reference
cold junction (internal
or external). Selecting “internal cold junction”, a Pt100 is directly connected
to the TC
input pins, measures the environmental temperature; whereas by selecting “external cold
junction”, the temperature value must be inserted by using the keyboard.

The next screen shows the Span parameter (measuring range). In the default settings, the sensor
has its maximum range equal to the measuring range (Span). If the Span has to be redefined, or to
be reduced, same can be changed by using a numeric keyboard. The redefinition of the Span is
used during a calibration for comparison where a relationship between a REF and a DUT channel
has to be done.
