Use Parameter.set or Parameter.cache.set methods instead. (#1857) Private method Parameter._save_val that has been spotted in use in instrument drivers is deprecated now. Use Parameter.set and Parameter.cache.set methods instead. (#1858) Recommended Dependencies: Type checking should be done with Mypy 0.750.
