Faulty KP184 Purple PCB
« on: November 02, 2024, 01:55:02 am »
Hi All,
        We use 20 KP184 at work for testing, all work ok with slight ripple , we have modded a few with suggestions from eevblog and improved the ripple. Will eventually do the rest. We recently bought three more from a different seller. And have had huge problems , we calibrate on the constant resistance setting, it jumps about so much that calibration is not accurate enough. The old units were not as bad. The seller has offered solutions but mainly saying increase resistance, and now out of ideas. I cannot find the manufacturers email to ask them. Has anyone had this problem PCB VER 0.71 purple all the old ones are blue .041 i think. Thankyou
