key until “Saved to DEF1/2” is displayed, 
which indicates the voltage and gain settings 
are saved to the DEF1 or DEF2 soft-key 
individually. 
  Trying to set the voltage outside of the voltage 
limit/range will result in a voltage setting error 
being displayed on the screen. 
  ACV, DCV and GAIN settings under each output 
mode and range have their own DEF1 and DEF2 
saved values, respectively.
