0. 990
or greater than
1.010,

until the number is within tolerance.
The adjustment of this control is extremely sensitive so, if an
adjustment is neccesary, do not turn it far in either direction.
Less than one degree ofrotation in either direction should bring
the drive speed into tolerance. A counterclockwise adjustment
will increase the drive speed, and a clockwise adjustment will
decrease the drive speed.

General Checkout
First time through "Diagnostic"?
The TEST program should now be running, with
a list of test functions printed on your console.
You
should
have
performed
the
"Drive Speed" procedure successfully. If the ro-
tational speed is incorrect, this and other tests
may give erroneous indications.
The purpose of "General Checkout" is to verify that your system is working
normally. Each sector on the diskette under test will be written and read a
number of times. Various patterns will be written on the sectors to allow the
testing of the head of the seek mechanism and the read/write head itself. The test
will automatically be repeated three times. Do not be alarmed if this test seems to
be taking an abnormally long time to finish.
It
is a very thorough test and requires
over
30
minutes. Rerun this test only if you encounter problems.
While each pass is being executed, the program will print the letters
"ABCDEFG", one after the other, at intervals of a few minutes. Xhese letters
indicate the various phases of the test and give you an idea of how far it has
progressed.
A message will be printed at the end of each pass. Here, there are two posibilities.
If everything proceeds normally, the output for the pass will read:
ABCDEFG END OF PASS
