D/A range as 0 V to 10 V. Next, write 0xFFFF to the
corresponding D/A registers (BASE+10 and BASE+12).
3. Write the value from 0x0400 to 0x04FF 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 to average those data for each
value. After that, 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.
4. Adjust GAIN 5V calibration. First, write any value to BASE+9 to
clear FIFO. Then set the A/D range as -5 V to +5 V, and set the
D/A range as 0 V to 5 V. Next, write 0xFFFF to the corresponding
D/A registers (BASE+10 and BASE+12).
5. Write the value from 0x0500 to 0x05FF 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 to average those data for each
value. After that, 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.
6. Adjust BIPOLAR offset calibration. First, write any value to
BASE+9 to clear FIFO. Then set the A/D range as -5 V to +5 V,
and set the D/A range as -5 V to +5 V. Next, write 0x0000 to the
corresponding D/A registers (BASE+10 and BASE+12).
