If you enter the service code to release the protection, the maintenance specific items in the setting
mode that are not displayed normally can be accessed and the parameters that are normally prohibited
to be rewritten can be changed.

this function.
If erroneously operated and the service code input screen appears, either press [CANCEL] to return to
the measurement mode or press [MENU/ENT] to go on to the setting menu. (In this case, protection
will not be released.)
