Using the 1-to-10 Adapter
The 1-to-10 Adapter, an optional accessory, is designed to
increase the number of lead or applied parts connections
to the Analyzer from five to 14. The adapter itself ties up to
ten leads together into a single lead that is plugged into
one of the input jacks of the Analyzer. The four remaining
Analyzer input jacks can also be used in conjunction with
the Adapter.
Figure 30 shows one application of the Adapter. The
Defibrillator/Monitor in the example has ten ECG leads,
two pacer leads, and two defibrillator paddles which need
to be tested together, and in groups if single function, for
current leakage per IEC62353. The example shows the
ECG leads to be snap type connectors and two BJ2ECG
adapters are shown plugged into the Adapter. If the ECG
leads did not have snap connectors, then the Universal
Snap to Banana Adapter can be used to make the
connections to the Adapter.
The common lead from the Adapter is plugged into the RA
jack (1 st jack) of the Analyzer. Using four sheathed test
leads with alligator clips, connect the two defibrillator
paddles into the LL and LA Analyzer jacks and the two
pacer leads into the RL and V1 jacks. Using the selection
that ties all five Analyzer jacks together will test all
fourteen leads for leakage current. Using the selection of
applied part group of 1, 2, and 2 allows for testing of
groups of applied parts of single function.
