1.2.15 Check Adaptor AD
Inspections after "Check adaptor AD" are optional. However, to check operations of all
functions, all inspections are basically necessary. This inspection checks if the voltage and
temperature sensor of the head and motor is working normally. Connect the AC adapter (not
optional battery base unit) to the machine before implementing this inspection.
(1) Make sure that the "Check adaptor AD" field is highlighted in yellow and press the [Run]
button to start the inspection.

Note : If the cover of the machine is open at the beginning of the inspection, VH Voltage will
not be output. Close the cover prior to the inspection.
(2) AD values to be checked appear in the "AD" field. Once all items result in "OK", the
inspection finishes and the window closes automatically.
Note : If any item is not "OK", press the [NG] button to finish the inspection.
