terminals of the Tester.
Alligator terminals
Figure 5-12. Connection of Lead Wire

the Gauge adjustment plate will move. Therefore, it is
recommended to use the cables whose rigidity is as low as
possible.

10. Move the Adjust parallelism bush (right) until continuity is confirmed. Raise the
Adjust parallelism bush (right) one step up from the position where continuity was
