C) Synchronization between cases
When two more cases are used, synchronization between the cases is needed. As shown in
Figure 3-8, it is possible to maintain synchronization by connecting the interface connectors on
the rear face of the case using synchronization cable (56-402). After the cases are connected,
one case should be set to INT using the synchronization selection switch 2 , and the other
cases should be set to EXT. Note that only amplifier units with the same bridge power frequency
can be installed in a case. It is impossible to share a common case or synchronize between cases
that have amplifiers installed with different bridge power frequencies. Take notice that the bridge
power frequency of Models 5683 is 5 kHz and that of Model 5684 is 25 kHz.
Do not set two or more units to INT. Otherwise correct measurement cannot be made, or this may
cause a defect in amplifier units.
