Isolation Switches
The 41-761 isolation switches on each channel provide the ability to disconnect the channels from the UUT, providing
the benet of not requiring the removal of cabling when wanting to isolate the UUT.

Thermocouple Simulation
The 41-761 connections to the front panel are copper based. Users should consider the consequences of using
thermocouple materials for connection to 41-761 channels.
