START-UP
The 2445 automatically performs power-up tests each
time the instrument is turned on. The purpose of these
tests is to provide the user with the highest possible con
fidence level that the instrument is fully functional. If no
faults are encountered, the power-up tests normally will be
completed in under five seconds, after which the instru
ment will enter the normal operating mode. 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 put the
instrument into the operating mode after a power-up test
failure, press the A/B TRIG button. If the instrument then
functions for your particular measurement requirement, it
may be used, but refer it to a qualified service technician
for repair of the problem at the earliest convenience.
Additional information on the power-up tests may be
found in Appendix A at the rear of this manual. Consult
your service department, your local Tektronix Service
Center, or nearest Tektronix representative if additional
assistance is needed.
