Pre-Adjust for Min Clipping
If this function is ON, it applies the adjustment described under "Adjust Atten for Min
Clipping" on page 1772 each time a measurement restarts. Therefore, in Continuous
measurement mode, it only executes before the first measurement.
In Dual-Attenuator models, you can set Elec+Mech Atten, in which case both
attenuators participate in the autoranging, or Elec Atten Only, in which case the
mechanical attenuator does not participate in the autoranging. This latter case
results in less wear on the mechanical attenuator and is usually faster.
