Connecting a DUT
NOTE
Connecting the interlock circuit
The M9601A provides an interlock function to prevent the user from receiving an
electrical shock from high voltages over the limit which is programmable, within
42 V. If the interlock terminals are open, the M9601A
cannot
apply a high
voltage.
For high voltage measurement, connect the interlock terminals to the interlock
circuit as described in
“Installing Interlock Circuit” on page 29
.
NOTE
Generally, environmental conditions, such as electromagnetic environment, have
a negative impact on the performance of the instrument. Use coaxial cable and
shielding technique to minimize the impact.
2-Wire Connections or 4-Wire Connections
When connecting a device under test (DUT), you can choose the connection type
either 2-wire connections or 4-wire connections.
If you want to simplify the connections, use 2-wire connections by connecting
the force terminals only, while the sense terminals will remain open.
To make 4-wire connections, well known as Kelvin connections, use both force
and sense terminals. Connecting the force and sense lines together at the
terminal of the DUT minimizes the measurement error by the residual resistance
of the test leads or cables. This connection is effective for low resistance
measurements and high current measurements.
