7.4 SPECIAL TOOLS
7.4.1 Extender flat cable.
For diagnostic testing and troubleshooting, a 3D-pole 50 cm extender flat cable can be used. Using
this extender flat cable makes it easier to separate the two units A 1 and A2 without breaking the
interconnection.
The ordering code for the extender flat cable is: 5322 321 61369.
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 recalibration must be done. If parts of the attenuator circuits and/or the
Analog ASIC 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 done.
If the original container is not available, repack the instrument so that no damage occurs during
transport.
