You can buy rather cheaply an IC that delivers rather accurate voltages. I
have several of them switch selectable and check my voltmeters from time to
time. They differ slightly from one another but when you average them you can
get pretty close.
Not the best way, but it works for me and should do if you aren't seeking the
best accuracy.
Several companies make these things and they are very close. Various voltages
are available but mine are 10V. I have some lower voltage ones in my junkbox
but so far haven't fooled with them.
