Only if your VOM can be used inline under load
and includes the capability of detecting ripple
voltages. In some cases, you can use the AC
range to detect ripple. The voltages seen should
nominally be under 100mVp-p. Just measuring
the voltages at the plug not under load is not
likely to tell you anything of interest.
I will say that if the power supply is 6 years old
the odds strongly point in it's direction as being
a contributor to "glitches", and I would replace it.
You should check the specs, but I believe it is
a standard 5V 2A supply. Hauppauge sells
replacements, or you can source it locally. You
may have "spares" from other devices available
for purposes of testing.
