The impedance is 100k Ω. Put a 50 kΩ resister in series with the voltmeter and map out the correction.

I never would have thought of that. You should get a Nobel prize!
Not as easy as it sounds if you don't have a 40k Ω resistor.
Solution:
Put _two_ voltmeters in series!
It werks up to 32.8 volts.
They LIED to me.
I just had a few shots of the good stuff and am feelin adventurous wif a fire extinguisher.
I gonna see how fur I kin git!
Don't drink all the shots. Sparks can ignite it for great fun.
An excellent money saving idea!
