I have never looked inside one, but there is probably a resistor inside that
regulates
the sensitivity. If it is adjustable, you are set. Otherwise, you could
possibly replace it
with a different value.
On the other hand, I have a cheap lab bench power supply with
a voltmeter what reads 20% low. Unfortunately, its resistance is
entirely contained in the windings, and there is no way to adjust it. :-(
