MC624 Monitor Controller / Re: high offset on u2/u5

I think you were right about the offset, I checked later and everything seemed fine and I was able to zero them out.

I still check for shorts on the IC/pins thank you!

MC624 Monitor Controller / high offset on u2/u5

« on: October 26, 2024, 02:06:54 AM »

the other two opamps zero'd fine, u2 shows around 14.8mv and u5 shows about 12.2mv without any more travel on the pot.

What should I look at?

also input 3 and 4 buttons, when one is pressed both LED's light up, but I can hear relays activating for each one individually. I don't actually care that much about the light assuming it works right.

Any input would be great.
