Universal Input Connections - Thermocouple (T/C)
Use only the correct thermocouple wire or compensating cable from the probe to the
instrument terminals avoiding joints in the cable if possible. Failure to use the correct wire
type will lead to inaccurate readings. Ensure correct polarity of the wires by cross-
referencing the colours with a thermocouple reference table.
