5.5 Self A/D Calibration

Under many conditions, it is difficult to find a good enough DC voltage source for A/D calibration. There is a simple method to solve this problem. First, you should calibrate D/A channel 0, DA0_OUT, with internal reference -5 V, and D/A channel 1, DA1_OUT, with reference -10 V.

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.
