When connecting to Models 2611B, 2612B, 2614B, 2634B, 2635B, and 2636B SMU outputs
using cables not rated for voltages above 42 V, such as the 2600A-ALG-2, you must disable
the high voltage output by using the INTERLOCK function as defined in Interlock (on page
6-42). Leaving the high voltage enabled while not properly insulating the external connections
to the instrument poses a shock hazard which could cause serious injury to the user. It is
also recommended that the LO connection terminal not be allowed to float by connecting it to
signal ground or another known signal reference.
