[sdiy] Power Supply Question

[The Peasant]

Quoting allenre at umich.edu:

> I have an HP 6205B dual power supply.
> 
> Both sides are havnig the same problem:  When I measure voltage from +/-
> inputs
> I only get the positive voltage, i.e. if the meter reads 15V my meter reads
> only +15V.  If I measure voltage from +VDC or -VDC to GND I don't get any
> reading (0V).

>From what you have written, I'd say the power supply is working correctly. Each 
side only puts out one voltage, between the + and - terminals. The ground 
terminal is only for referencing the output to ac ground, which is why you 
won't normally get a reading between it and the other terminals. Most older HP 
supplies work this way.

Take care,
Doug
