4.2    Characteristic change 

            If at this point channel 1 outputs 6000 when the actual measured temperature is 600°C, channel 2 outputs 1200 when the 

actual measured temperature is 120°C and channel 3 outputs 2480 when the actual measured temperature is 248°F. Receive the 

average conversion result with data registers D1, D2 and D3. The changes are shown in Figure 4-4. Note that the characteristic 

changes are all in degrees Celsius. The range for setting the change value is within ±1000 (±100°C).
