3.6.2 To connect interlock circuit
The B1500A provides the Interlock connector to prevent you from receiving an electrical
shock from high voltage (more than ± 42 V). If the interlock circuit is open, the B1500A
cannot apply high voltage more than ± 42 V.
Before performing measurement, connect the 16493J interlock cable between the B1500A
Interlock connector and the interlock connector which is a part of the interlock circuit
installed in your DUT interface as described in the previous section.
