The 10.000208V output setting is calculated by the calibrator using the following
equation:
This is applied to 10V to yield the following:
The 1.3 mV zero offset is then subtracted:
8. Use the output adjustment controls to adjust the calibrator's output for a reading of
10.0V (the reference value) on the DMM. The displays change to:

The Control Display now shows that the DMM scale error at 19.9V is -0.0151%, and the
DMM linearity error at 10V is +0.0352%.
