EXTERNAL TEMPERATURE SE
CALIBRATION WINDOW
The External Temperature Sensor Offset Calibration window
is used to calibrate the temperature, correcting errors attributab
to noise that may be coupled onto the Dx+ and Dx− lines of th
remote temperature sensors. Both T
SENSE
1 and T
SENSE
2 can be
offset using the gauges shown in Figure 25. The gauges can be
adjusted from between −32°C and +31.75°C, and the resulting
value is automatically subtracted as a twos complement 8-bit
reading from every temperature measurement before the value
is stored in the relative result reg
