FIGURE 3. Differential Measurement of Type T Thermocouple
4.2 Differential Analog Measurements
Connect one differential sensor to a differential AM25T input channel.
Connect the sensor shields to the ground terminals next to the input channel.
Up to 25 differential sensors may be measured by one differential channel on
the datalogger (Figure 4).
