Check upon Completion of Adjustment
1. Tracking Check
1)
Play back the tracking alignment tape (XH 2-1) (Ref. No. J-8).
2)
Establish the CUE (or REV) mode. Take the amplitude (A)
in this mode as the 100% waveform amplitude. (Refer to Fig.
6-1-16.)
3)
Establish the FWD mode. Confirm that the difference between
the minimum (E min) and the maximum (E max) is less than
30%. (When taking the amplitude (A) in the CUE or REV mode
as 100%)
4)
Confirm that the RF waveform does not have excessive
fluctuation of amplitude. (Fluctuation of amplitude should be
10% or less at both entrance side (B) and exit side (C), when
taking the amplitude (A) in the CUE or REV mode as 100%)

2. CUE/REV Check
1)
Play back the tracking alignment tape (XH 2-1) (Ref. No. J-8).
2)
Establish the CUE mode. Confirm that the pitches between the
peaks of the RF waveform are equally spaced. Also confirm
that the RF waveform amplitude at entrance side (B) and exit
side (C) is 50% or more respectively, when taking the amplitude
(A) in the CUE or REV mode as 100%.
3)
Establish the REV mode. Confirm that the pitches between the
peaks of the RF waveform are equally spaced. Also confirm
that the RF waveform amplitude at entrance side (B) and exit
side (C) is 50% or more respectively.
3. Rise-up Check
1)
Play back the tracking alignment tape (XH 2-1) (Ref. No. J-8).
2)
Change the modes from CUE mode to FWD. Confirm that the
RF waveform rises up within two seconds when the mode is
changed from CUE mode to FWD.
3)
Change the modes from REV mode (two seconds or more of
REV and to the FWD within five seconds) to FWD. Confirm
that the RF waveform rises up within two seconds when the
mode is changed from REV mode to FWD.
4)
Change the modes from STOP mode to FWD. Confirm that
the RF waveform rises up within two seconds when the mode
is changed from STOP mode to FWD.
