Associating CJC channels with thermocouple channels
TC channels must immediately follow their associated CJC channels in the channel array. For accurate
thermocouple measurements, associate CJC channels with the TC channels as listed below.
CJC channels TC channels
CJC6 TC8 through TC11
CJC7 TC12 through TC15
CJC8 TC16 through TC19
CJC9 TC20 through TC23
CJC10 TC24 through TC27
CJC11 TC28 through TC31
When measuring thermocouples, configure the USB-2416 Series device for differential inputs.
