Thermocouples consist of a thermoelement, that is a junction of two specified dissimilar wires that poduce a small temperature dependent voltage.

• K Inputs are intended for use with Type K thermocouples, that is Chromel/Alumel (Ni-Cu/Ni-Al) thermocouples. Temperatures up to 1370ºC can be measured. Type K sensors are preferred and should be used unless there is a very good reason not to!
• T Inputs are intended for use with Type T thermocouples, that is Copper/Constantan (Cu/Cu-Ni) thermocouples, permitting temperature measurement up to 350ºC with greater accuracy than Type K thermocouples.
• CJC (Cold Junction Compensation) is built into the Squirrel (for explanation of CJC see FAQs). This, together with thermocouple connectors and special connecting leads available for thermocouple sensors assures reliable and accurate temperature measurement.
• Refer to the table "Special Range Setting" for inputs assigned to other thermocouple types such as C, D, E, J, N, R, S and enhanced K and T.
