Memo
Kelvin Sense
Since voltage drop caused by the
contact resistance of a contact is
not included in measurement, high
accuracy measurement can be
attained.
3.3.3 Connecting the patch panel (only for CS-302)
Connection of the patch panel uses the attached Test Lead. There are 4 connection methods;
HIGH VOLTAGE mode and HIGH CURRENT mode using patch panel, and HIGH VOLTAGE
mode and HIGH CURRENT mode using direct connection to a measured device without use of the
patch panel, which can be selected depending on your application. Connection of the patch panel
requires only the test fixture CS-302 (not CS-301).
(1) For HIGH VOLTAGE
Connection of terminals on the test fixture in HIGH VOLTAGE MODE is shown below. If the
measured device generates oscillation, it should be connected to BASE/GATE 1K Ω terminal as
shown by the dotted line to prevent the oscillation.
(2) For HIGH CURRENT
When large current is applied to a measured device, connect the device to SENSE terminal
and perform Kelvin Sense to achieve the high accuracy measurement. Be sure to connect to
SENSE terminal for measurement with high accuracy.
If connection to SENSE terminal is not made in HIGH CURRENT mode, no device can be
measured.

Caution
！
At HIGH VOLTAGE MODE,
connect Collector terminal using
RED color wire which comes
with this unit as standard
accessory and carefully avoid
incorrect wiring.
These connections may cause
of damage on DUT and/or
malfunction of the unit.
