Then, run the ADCAL.EXE program to finish the self-A/D
calibration procedure.
1. Set AI0 as differential, bipolar, range ±5 V and AI2 as
differential, unipolar, range 0 to 10 V.
2. Connect DA0_OUT with codes equal to 4095 LSB (4.9959 V) to
AI 0. Notice that the polarity of AI0 should be connected with
reverse polarity (i.e. D/A + to A/D -, D/A - to A/D +).
3. Adjust VR2 until the output codes from the card's AI0 flicker
between 0 and 1.
4. Connect DA0_OUT with codes equal to 4095 LSB (4.9959 V) to
AI0.
5. Adjust VR3 until the output codes from the card's AI0 flickers
between 4094 and 4095.
6. Repeat steps 2 through 5, adjusting VR2 and VR3.
7. Connect DA1_OUT with codes equal to 1 LSB (2.44 mV) to
AI2.
8. Adjust VR1 until the output codes from the card's AI1 flicker
between 0 and 1.
9. Finish ADCAL.EXE.
