7.4 SPECIAL
TOOLS
7.4.1 Extender flat cable.
For diagnostic
testing and troubleshooting, a 30-pole 50 cm extender flat cable
can be used. Using
this extender
flat cable makes it easier to separate the two
units A1 and A2 without breaking the
interconnection.
The ordering code for the extender
flat
cable
is: 5322 321 61 36S.
7.5 RECALIBRATION
AFTER REPAIR
After any electrical component has been replaced the performance
of that particular circuit should
be
checked, as well as the performance
of other closely- related circuits. If necessary
a
recalibration
must be performed. Since the power supply influences
all circuits, the performance of the
entire
instrument should be verified if work has
been done in the power supply or if the transformer has been
replaced. If necessary a recalibralion must be done. If parts of
the attenuator circuits and/or the
Artaiog AStC
have been replaced, It might be necessary
to do Hardware SCOPE Calibration
Adjustments.
Refer to section 5.6.1 of this Service Manual.
7.6 INSTRUMENT REPACKING
If the ScopeMeter is
to be
reshipped
to a Service Centre for service
or repair, attach a tag showing
the full address
and the name of the individual at the users firm that
can be contacted.
The Service Centre needs the complete
ScopeMeter, Including the RED and the GREY
scope
probe, its serial number, and a complete description of the
problem and the work that is to be dons.
If the original container is not available, repack the
Instrument so that no damage occurs during
transport.
