The measurement function to which this setting applies:
• Current: CURRent[:DC]
• Resistance: RESistance

The lower limit:
• Current: 1e-8 to 1 amps
• Voltage: 0.02 to 200 volts
•
Resistance: 2 to 2.0e8 ohms
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.
While you can send any value when you send this command, the instrument select the next highest range value.
For example, if you send 15 for the lowest volt range, the instrument will be set to the 20 V range as the low limit.
If the lower limit is equal to the upper limit, automatic range setting is effectively disabled.
Example
:VOLT:RANG:AUTO:LLIM?
Set the low range for voltage measurements
to 20 V.
