The 2606B connections for the floating configuration are shown below.
Figure 36: Connections for floating a SMU
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
PEAK
is present in the test circuit. Appropriately rated
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
(on page 2-59)).
DUT connection settings
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.
Sense mode selection
The sense mode can be set to use
2-wire local sensing connections
(on page 2-57).
The default sense setting is 2-wire local.
