Details
This command sets the source limit for measurements. The Model 2461 cannot source levels that
exceed this limit.
The values that can be set for this command are limited by the setting for the overvoltage protection
limit.
This value can also be limited by the measurement range. If a specific measurement range is set, the
limit must be more than 0.1 % of the measurement range. If you set the measurement range to be
automatically selected, the measurement range does not affect the limit.
If you change the source range to a level that is not appropriate for this limit, the instrument changes
the source limit to a limit that is appropriate to the range and a warning is generated.
Limits are absolute values.
Example
:SOUR:CURR:VLIM 15
Set the voltage limit to 15 V.
