Error Checking and Soft Limits
The AC6800 Series instruments include error checking measurements and soft limits that prevent
unintended operations from being carried.
Basic Principles
Settings are not automatically changed by either front-panel or SCPI commands, unless the changes
are obvious and expected.
Improper settings or combination of settings are not allowed for active settings.
User actions which would result in improper active settings generate error messages.
Inactive settings are not checked for errors in response to range changes. If these settings will
become active due to output mode changes, such as switching coupling from AC to DC, or due to the
enabling of soft limits, error checks are performed before making the settings active.
Error checks should be performed in response to the following events:
Changing Settings invokes Settings Error Checking
Enabling soft limits invokes Settings Error Checking
Changing ranges from high to low invokes Range Error Checking
Changing output coupling invokes Output Coupling Error Checking
Changing to Step mode invokes Settings Error Check
