Just picked up a cheap (at least I think so) VFD. I am looking at the Campbell card to control the VFD.
From what little I know about VFDs the interfaces all should be the same. Correct me if I am wrong. In other words, I should have no problem running the Campbell board to most newer VFDs???
Any cheap ways to calibrate the thing? I have heard that they can be relied upon without the calibration. Is this true? If not any cheap ideas how to check? No I have no access to a laser tach.
Thanks in advance,
VFD I won:
