Connecting Thermocouple Inputs

The DT9871U, DT9871, and DT9874 instruments contain Cu-Cu thermocouple jacks for

connecting thermocouple inputs.

Note: On the standard DT9874 instrument, channels 0 to 15 correspond to the thermocouple
input channels.
Internally, these signals are connected in differential mode. You can mix and match the
following thermocouple types across channels: B, E, J, K, N, R, S, and/or T.
Each Cu-Cu thermocouple input jack is polarized and accepts a mating Cu-Cu plug in the
appropriate orientation.
supported thermocouple types for both the ANSI (American) and IEC (International)
