6. INSPECTION AND CHECK PROCEDURES
Measurement
(1) Set the Filter parameter to Off, then adjust the oscillator’s output level to achieve an appropriate ampli-
tude when the oscillator is inputting a 1-Hz frequency (the reference signal input).
(2) In the above status, turn on the printer and then record (print) the amplitude of the reference signal input.
(3) Specify the Filter setting and the input signal frequency from the oscillator according to Table 6-2-5. (Set
the output level to match that of the reference signal input.)
(4) Check that the measured amplitude is within the standard when compared with the amplitude during
reference signal input.
