Dut Connection Settings - Keithley 2606B System SourceMeter Reference Manual

Section 2: General operation
The 2606B connections for the floating configuration are shown below.
The maximum floating (common mode) voltage for a source-measure unit (SMU) is ±250 V.
Exceeding this level may cause damage to the instrument and create a shock hazard.
Using an external source to float a SMU could create a shock hazard in the test circuit. A
shock hazard exists whenever >42 V
cables or insulators must be provided for all connections to prevent access to live parts.
When >42 V is present, the test circuit must be insulated for the voltage used or surrounded
by a metal safety shield that is connected to a known protective earth (safety ground) and
chassis ground (see

Make sure to properly configure the 2606B sense mode for the specific DUT test connection scheme.
Use care to configure the output-off state to supplement safe operation of your test setup.
