This menu sequence is obtained by selecting
linearity of the 1kV DC range to be calibrated with the application of five input signals of
-1000V, -500V, 0V, +500V and +1000V in turn, with the 1kV DC range selected. On
entry to the menu, the user is prompted to apply the first input signal required and step
through the sequence:

Non-volatile input offset compensation

Good metrology practice should ensure that all high-precision measurements made with
the 8508A are preceded by an input zero of each measurement. However, a non-volatile
input-offset compensation is independently available for the front and rear inputs and will
be used whenever the input zero capability is not in use. The compensation is retained
after power down, is unaffected by clearing the volatile input zeros, and is unaffected by
range zero calibration adjustments. Compensation is available on all functions, and
includes separate compensation of 2-wire and 4-wire measurements in the resistance
functions.
