Setting up THCAD-5 with 7i96

If someone doesn't spot an obvious error you've made you could always disconnect the plasma and attach a LV DC power supply and verify readings/calibration against a multimeter...


So if I understand correctly you're suggesting to hook up a known voltage such as from my 24v power supply, in place of where the voltage divider is located, then I can adjust the scale to reflect the 24v on the readout?

You need to get the zero voltage correct first. Are you 100% sure it is set to 50:1

What if you try -4290.625

I just now after reading your post realized that the - sign was missing from the scale. Okay the problem is fixed now I believe, as I have 0v now that it's changed. When torch is fired it shows around 120v. I will go see if I can cut some things now, thank you!

Do what now? :huh:

Just for my own edification what's going on here? I wouldn't think either the scale as raz mentioned, or the offset as phill mentioned, should be negative. Since FFS > FZERO then the scale should be positive. And since FZERO > 0 then the offset should be positive.

Does it have to do with hal config settings?
