Autoranging
To use automatic source ranging, press
SRC
then the
AUTO
range key. To use automatic measure
ranging, press the
MEAS
key followed by the
AUTO
range key. The AUTO indicator turns on when
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
The low range limit sets the lowest range that the Series 2600B will use when autoranging is enabled.
This feature is useful for minimizing autorange settling times when numerous range changes are
involved.
To individually set low range limits for Source V, Source I, Measure V, and Measure I:
1. Press the
CONFIG
key, then press either the
SRC
key (for source) or the
MEAS
key (for
measure).

key or the navigation
wheel .
