Explanation
Test Type (Type)
Memory: Tests whether or not the internal CPU board RAM and ROM are operating properly. If they
are operating properly, "Success" appears. If an error occurred, "Fail" appears.
Keyboard: Tests whether or not the front panel keys are operating correctly and whether or not the
soft keyboard accepts input properly.
• The front panel keys are operating properly if the background color of the names of the
keys that you press turns white or green.
• Knobs are operating properly if you turn them slowly, press them, or move them up,
down, left, and right depending on the type of knob and the background color of the
names or arrows changes to white or green.
• The soft keyboard is operating properly if you can enter the specified characters.
Printer:
Tests whether or not the optional built-in printer is operating properly. The built-in printer is
operating properly if the print density is correct. If an error occurs, the print density will not
be correct.
Note
Accuracy is a service test item. Under normal circumstances, you do not need to perform these tests.
If an Error Occurs during a Self-Test
If an error occurs even after you carry out the following procedure, contact your nearest YOKOGAWA
dealer.
• Execute the self-test again several times.
• Confirm whether or not the media being tested is properly inserted.
• Check that the paper is set properly in the built-in printer and that the paper is not jammed.
