Good morning,

I recently bought three HP power supplies, the 6263B and the 6267B and all experiencing the same problem.

I do not get any voltage out of them; I was wondering if there is some trick I don’t know about.

?

I do have the operating / service manual.

?

These do not have the built in variable pot.

So, I have to wire them with “resistance programming of output voltage” as seen on fig 3-4.

?

I am using a 1000 ohm resistor for my programming resistor that should produce 5 volts (200 ohm per volt calculation)

?

I am using a 520 ohm load resistor.

?

When I turn the power off, I see the volt meter needle rise then bleed off.

?

Any ideas on what I may be overlooking? This is my first time playing with this programming of output voltage type.

?

Thanks,

Rick T
