(a)
While holding down the
CE
switch, press the
TEST
switch.
Response:
The
DIAGNOSTICS
indicator lights and the display reads
00
.
(b)
Press the
STEP
switch until
06
appears on the display.
(c)
Press the
TEST
switch.
Response:
Display reads
60
.
(d)
Press the
STEP
switch until the display reads
64
.
(e)
Press the
EXECUTE
switch to run test 64. This test determines the optimum write current level for all
nine tracks.
Response:
The display reads
00
if the test is complete.
(f)
After test 64 completes, press the
RESET
switch.
8.
Perform CE test 31 as follows:
NOTE:
Test 31 sets up and checks read amplitudes at 25 and 75 ips. At 25 ips, it determines the minimum
gain value for each track, and stores them in backup memory. It again determines the minimum
gain value for each track and compares it to the previously stored value. If the difference in gain
between the 2 values for any track is such that it causes an amplitude difference of 0.1 volt, the test
is repeated. Also, if any fault is detected while determining the minimum gain values, the test is
repeated. If, after 5 attempts, the operation is not successful, a fault is reported.
(a)
While holding down the
CE
switch, press the
TEST
switch.
Response:
The
DIAGNOSTICS
indicator lights and the display reads
00
.
(b)
Press the
STEP
switch until
03
appears on the display.
(c)
Press the
TEST
switch.
Response:
The display reads
30
.
(d)
Press the
STEP
switch until the display reads
31
.
(e)
Press the
EXECUTE
switch to start test 31. This test checks read amplitudes on successive tries and
compares them.
Response:
The display indicates
00
if the test is successful.
(f)
If the display did not indicate
00
, seek technical assistance. Otherwise, continue with the next step.
9.
Maintain power on (do not power down) the tape drive while performing these final steps or else the test
results will be lost and the tests will have to be repeated.
10.
If previously moved, return the servo/control board jumper (W1) to its original position (pins 2-3).
