Details
This command sets the source limit for measurements. The Model 2450 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 source limit is changed to a limit
that is appropriate to the range and a warning is generated.
Example
:SOUR:CURR:VLIM 15
Set the voltage limit to 15 V
