When connecting to the model 2611, 2612, 2635 and 2636 SMU
outputs, with cables not rated for voltages above 42V, such as the
2600-ALG-2, you must disable the high voltage output by using the
INTERLOCK function as defined in section 10 of this manual.
Leaving the high voltage enabled while not properly insulating the
external connections to the unit poses a shock hazard which could
cause serious injury to the user. It is also recommended that the

signal ground or another known signal reference.
