Explanation
Turning the Limiter ON/OFF
ON: The limiter is activated at the specified limit values.
OFF: The limiter is activated at the boundary of the source range (see section 2.3).
However, the limit values are not displayed.
Tracking
ON: Sets the limit values with the same absolute value but with opposite signs.
Example High limit value: +1.00000 mA
Low limit value: −1.00000 mA
OFF: Set the limit values to arbitrary positive and negative values.
Example High limit value: +1.50000 mA
Low limit value: −1.00000 mA
Setting the Limit Values
In voltage source mode, the current limiter is enabled. In current source mode, the
voltage limiter is enabled.
The optimal limiter range for the specified limit values is automatically selected.
