5 Apply the input voltage per the input column in Table 2-8 and allow for
appropriate source settling.
6 Enter the calibration value per the applied input current in step 5 and press
Perform Cal Step to begin the adjustment procedure (see “Entering calibration
values” on page 46).
7 A “Calibration Step Succeeded” message indicates success; if the display
shows “Calibration Step Failed”, check the input value, range, function, and
entered calibration value, and repeat the calibration step.
8 Repeat step 5 to step 7 for each gain calibration point.
9 Store the new gain calibration constants (see “Storing calibration constants”
on page 46).
