C.3 D/A Calibration (PCI-1710U/HGU)
In a way similar to the A/D Calibration, the D/A calibration tool in the
Advantech Device Manager leads you through the whole D/A calibration
procedure.
1. Measure the DA0 output with a 4 1/2-digit digital meter. Adjust the
VR4 until the output value equals 4.9988V.
Note: Using a precision voltmeter to calibrate the D/A
outputs is recommended.
