Details
You can use this command when automatic range selection is enabled. It prevents the instrument
from selecting a range that is below this limit. Because the lowest ranges generally require longer
settling times, setting the low limit that is appropriate for your application but above the lowest
possible range can make measurements require less settling time.
The lower limit must be less than the upper limit.
Though you can send any value when you send this command, the instrument selects the next
highest range value. For example, if you send 15 for the lowest voltage range, the instrument will be
set to the 20 V range as the low limit.
Example
:VOLT:RANG:AUTO:LLIM 15
:VOLT:RANG:AUTO:LLIM?
Set the low range for voltage measurements
to 20 V.
Output:
2.01
