Clear and sanitize procedures
NOTE. Sanitizing or clearing the instrument cannot be reversed. But the
instrument application software and calibration information is left unchanged
after the sanitizing or clearing operations. There is no need for a post-
sanitization or clear procedure for the MDO3000 Series of instruments. The
instrument can begin normal use and function immediately after the sanitizing or
clearing procedures.
