Accuracy of measurements
The curves below show the maximum measurement error
(measurement and repeating accuracy).
Total error = linearization error + repeating error
Each channel is calibrated to the minimum and maximum values:
-50 °C → 0 + 2 LSB
+150 °C → 4095 - 2 LSB
For these two values, the measurement error = 0.
