Details
Auto range selects the best range in which to measure the signal that is applied to the input terminals
of the instrument. When auto range is enabled, the range increases at 120 percent of range and
decreases occurs when the reading is <10 percent of nominal range. For example, if you are on the 1
volt range and auto range is enabled, the instrument auto ranges up to the 10 volt range when the
measurement exceeds 1.2 volts. It auto ranges down to the 100 mV range when the measurement
falls below 1 volt.
This command determines how the range is selected.
When this command is set to off, you must set the range. If you do not set the range, the instrument
remains at the range that was selected by autorange.
When this command is set to on, the instrument automatically goes to the most sensitive range to
perform the measurement.
If a range is manually selected through the front panel or a remote command, this command is
automatically set to off.
When the TERMINALS switch is set to REAR and autorange is enabled, autoranging is limited to
ranges up to 3 A ranges. The 10 A range is not included in the autorange algorithm.
Example
RES:RANG:AUTO ON
Set the range to be selected automatically
for resistance measurements.
