Connecting a DUT
Connecting the interlock circuit
The M9602A/M9603A provides an interlock function to prevent the user from
receiving an electrical shock from high voltages over the limit. The limit is
programmable within
42 V. If the interlock terminals are open, the M9602A/
M9603A
cannot
apply a high voltage over the limit.
For high voltage measurement, connect the interlock terminals to the interlock
circuit as described in
“Installing Interlock Circuit” on page 31
.
Generally, environmental conditions, such as electromagnetic environment, have
a negative impact on the performance of the instrument. Use coaxial cables and
shielding technique to minimize the impact.
2-Wire Connection or 4-Wire Connection
When connecting a device under test (DUT), you can choose the connection type
either the 2-wire connection or the 4-wire connection.
If you want to simplify the connection, use the 2-wire connection by connecting
the force terminals only, while the sense terminals remain open.
To make the 4-wire connection, well known as Kelvin connection, 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.
