Warning: Data Not Stored - 881, 882
On occasion an 881 or 882 will report "Warning: Data Not Stored" even when all settings appear to be properly configured; i.e., a storage channel is active and "REF" is in uppercase. If all else fails a factory reset may be required to bring the instrument back into good working order (see Related Support). Make every effort to ensure correct configuration settings first as a reset will completely erase all stored data.
