Menu
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 is mainly used by service personnel, it is not necessary for general customers to enter 
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.)
