Use the following criteria to determine if the writer passed or failed the
50mm/s speed test.
• If one cycle of the square wave spans 50 mm on paper, measured from
corner to corner of the wave, with an allowable tolerance of 1.0 mm,
the test passes.
• If this criteria is not met, the test fails.
If the test passed, press F4 (Yes).
If the test failed, press F5 (No).
If one cycle of the square wave spans 25 mm on paper, measured from
corner to corner of the wave, with an allowable tolerance of 0.5 mm (2%),
the test passes.
If this criteria is not met, the test fails.
Measure five or more cycles and divide your measurement by the number
of cycles measured.
