Hardly, it would be perfectly adequate for the job actually.


Wrong. That could easily leave the scope over 6% off.

It takes a much finer source to calibrate a device than the final
accuracy of the device being calibrated, dip****.


Not in this case.
If he used a meter with 0.5% accuracy on DC volts then he could check
and adjust his scope's vertical scale to the same 0.5% accuracy.

And if you start crapping on about the tolerance of the resistor chain
adding up etc, then you haven't thought about this one hard enough...
