(Set value)
The [EXECUTE] key is highlighted, the adjustment value entered
in procedure 2 is set, and the voltage corresponding to the set
value is outputted.
The voltage is supplied for 30 sec, then the [EXECUTE] key
returns to the normal display.
If the [EXECUTE] key is pressed while the voltage is supplied, the
voltage output is stopped and the [EXECUTE] key returns to the
normal display.
