AUTO
range key. To use automatic measure
ranging, press the
MEAS
key followed by the
AUTO

source or measure autoranging is selected. With autoranging selected, the instrument automatically
sets the best range to source or measure the applied signal. The instrument will uprange at 100
percent of the present range.
When you change a source value, source autoranging is automatically turned off and remains off
until you re-enable it.
Low range limits

involved.
