FC3000 dimmer problem

[CannabisMingus]

When I adjust my dimmer from 75% to 100% PAR reduces instead of increases (in this specific instance from 560 to 480 using a Photobio PAR meter). Any suggestions on how to fix?

Have you checked for loose connections, faulty earth etc..

Yes. Everything looks good.

Can you see an increase/decrease in the light? Hold a piece of white paper at canopy top and watch the paper as you turn the power up.

I can see a decrease when dimmer goes from 75-100 - consistent with what I see on my PAR meter.

It appeared to be a rheostat issue. I kept working it and it seems to have cleared whatever was causing the issue. Thanks guys.
