ence junction may be inconvenient but it will provide more accurate temperature measure-
ments (assuming the user enters a precise reference temperature).
With open thermocouple detection disabled, the Model 2750 can calculate the average
temperature of two thermocouple channels using Channel Average (see Section 5 for
details). As shown in Figure 3-8D, one thermocouple is connected to a primary channel (1
through 10), and the other thermocouple is connected to its paired channel (11 through
20). Channel 1 is paired to channel 11, channel 2 is paired to channel 12, and so on. Keep
in mind that a simulated reference junction (i.e. ice bath) can instead be used for these
thermocouple temperature measurements.
