Hi to all, I've finished populating the psu board v3. Now I'm testing it such as suggested in the guide. But if I use my dmm pointing on v+(-) and gnd it starts beeping but then stops and the value increases. Instead if I us the dmm at 20k ohm it displays 1k and increases slightly. ????? Help me.
Hi Acumos
My thoughts are you are trying to measure resistance OHMS with DC voltage switched on. Most DMM's don't like this, and although they should not interfere with circuitry - its possible a cheaper DMM may do just that
Suggest you turn power off to then measure resistance. It would help to explain to us what the v3 psu board is, and attached to.
So switch power off before measuring resistance.
Cheers / Chris
thank for your reply. The psu board v3 is the one sold by diyaudio store and I'm testing it unwired prior to connect it in my f5
As Zen Mod stated, you are charging the caps when you connect your DVM. If you leave it connected long enough you should reach a steady state highish value (KOhms), depending on the caps used.
