HARD FLOW

This sub-menu is used to check operation of the flow port
of the hardware. "OK" appears when the check result is
satisfactory and "NG" when it is not.

11.AD DATA CHECK

This menu is used to display the A/D conversion value
of the main Microprocessor which detects panel keys
of the main unit and protection functions in using the
sub-menu. During signal processing, the condition be-
fore execution is maintained.
When K0/K1 menu is selected, keys become non-op-
erable due to detection of the values of all keys. How-
ever, it is possible to move to the next DIAG menu by
turning the PROGRAM knob of the main unit.
