section of this manual. Consult your service department,
your local Tektronix Service Center, or nearest Tektronix
representative if additional assistance is needed.
The oscilloscope automatically performs a set of diag-
nostic tests each time the instrument is turned on. These
tests warn the user of any available indication that the
instrument may not be fully functional. The tests run for
several seconds after power is applied. If no faults are
encountered, the instrument operates normally. A failure of
any of the power-up tests will be indicated by either a
flashing TRIG'D indicator on the instrument front panel or
a bottom-line readout on the CRT in the form: TEST XX
FAIL YY (where XX is the test number and YY is the
failure code of the failed test).
If a failure of any power-up test occurs, the instrument
may still be usable for some applications. To operate the
instrument after a power-up test failure, press the A/B
TRIG button. Even if the instrument then functions for
your particular measurement requirement, it should be
repaired by a qualified service technician at the earliest
convenience. Additional information on the power-up tests
REPACKAGING FOR SHIPMENT
