10. AD DATA CHECK
This menu is used to display the A/D conversion value of the main CPU which detects panel keys of the main unit and
protection functions in % using the sub-menu. (Reference voltage 5V as 100%) During signal processing, the condition
before execution is maintained.
When in K0/K1 page, it is not possible to operate the keys of the main unit because the values of all keys are detected. But
one click on the volume encoder of the main unit to the right or left will cancel this function and sets to the next sub-menu.
Note, however, that clicking there more than once would change the DIAG menu. In such a case, return to the DIAG menu
which has been used for measurement. During signal processing, the condition before execution of this menu is maintained.
