10.6. Special Calibration Requirements for Dual Range or Auto
Range
If Dual Range or Auto Range is selected, then calibration for Range1 and Range2
should be performed separately.
For zero and span point calibration, follow the procedure described in Section 9.2.
Repeat the procedure for both the HIGH and LOW Ranges.
