9. Write the value from 0x0300 to 0x03FF sequentially to the
Calibration Command and Data register (BASE+18), and get
each bipolar range' s data by the software trigger A/D method.
Repeat this procedure 1000 times then average those data for each
value. See whether the average data is close to 65534.6. If so, go
to the next step. Otherwise, you must change the value and repeat
the whole procedure in this step again until the average data is
close to 65534.6.
10. Repeat steps 2 to 9 several times.

Note
n 1 LSB = FS / 65535 for Unipolar
(For example: 1LSB = 10 / 65535, while the range is 0 V to10 V)
n 1 LSB = +FS / 32768 for Bipolar
(For example: 1LSB = 5 / 32768, while the range is –5 V to +5 V)
