The 10.000208V output setting is calculated by the calibrator using the following
equation:
1 −
19 9 19 903
19 9
..
.
VV
V
= 1.0001508
This is applied to 10V to yield the following:
10V x 1.0001508 = 10.001508V
The 1.3 mV zero offset is then subtracted:
10.001508V − 0.0013V = 10.000208V
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:
Output Display
Control Display
UUT (DMM) Display
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%.
