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.
