Connections
2-5
Input/output LO and chassis ground
Input/Output LO is not directly connected to chassis ground. For test circuits that require
Input/Output LO connected to chassis ground, you can use the supplied chassis ground plug.
Connect the lug end of the cable to the chassis ground screw on the rear panel of the main-
frame, and plug the other end into the INPUT/OUTPUT LO banana jack.
With no Input/Output LO-to-chassis ground connection, floating source-measure operations
(up to 42V peak) can be performed. Inside the mainframe, a zener clamp (Figure 2-1C) is used
to isolate Input/Output LO from the chassis.
WARNING
Exceeding 42V between Input/Output LO and chassis ground creates a
shock hazard and could cause damage to the SourceMeter that is not cov-
ered by the warranty.
CAUTION
Do not connect any external sources between Input/Output LO and chassis
ground. Current exceeding 10.5mA will damage the zener clamp
(Figure 2-1C). Such damage is not covered by the warranty.
Test
fi
xture interlock
A test fixture interlock switch can be used with the SourceMeter to help protect the DUT.
The SourceMeter output will turn off when the lid of the test fixture is opened. However, you
must ALWAYS assume that power is present until you verify that the SourceMeter output is
off.
WARNING
To prevent electric shock, test connections must be configured such that
the user cannot come in contact with conductors or any DUT that is in
contact with the conductors. Safe installation requires proper shields, bar-
riers, and grounding to prevent contact with conductors. Operator protec-
tion and safety are the responsibility of the person installing the product.
See Section 12 for complete details on using the interlock and output configuration
information.
