5.3 Setting the Limiter
Explanation
Turning the Limiter ON/OFF
ON:
Apply the limit with the specified limiter values.
OFF: The limiter is activated at the maximum value of the source range (see section
2.2). However, the limiter value is not displayed.
Tracking
ON:
Set the limiter values with the same absolute value but with opposite signs.
Example Hi limiter value: +1.000 mA
Lo limiter value: –1.000 mA
OFF: Set the limiter values to arbitrary values with opposite signs.
Example Hi limiter value: +1.500 mA
Lo limiter value: –1.000 mA
Setting the Limiter Value
The current limiter is selected when generating voltage, and the voltage limiter is
automatically selected when generating current.
The optimal range for the specified limiter values is automatically selected.

Display When the Limiter Is Activated
When the high limiter is activated: High limiter activation display (H)
When the low limiter is activated: Low limiter activation display (L)
Note
• If the limit values are set outside the source range of the selected range setting, the limiter
is activated at the boundary of the source range.
• If the limiter range is changed, the limiter level is transiently reduced to 10% of the range
setting and moves sequentially to the adjacent ranges.
