Note About Recovering Compensation Values
When the :CORRection:OPEN RETurn is carried out, disabled open
circuit compensation values can be retrieved, but when open circuit
compensation is carried out again after the circuit compensation val-
ues are disabled, the pre-disabled open values cannot be retrieved.
Refer to the following examples.
Example of a retrievable circuit compensation value.
Example of a non-retrievable circuit compensation value.
