Local Sense and Remote Sense
(See section 4.5 for the procedure)
Two wiring systems, 2W (two-terminal connection or local sense) and 4W (four-terminal
connection or remote sense), are available. When generating voltage and the current
flowing through the load becomes large, the voltage drop in the lead wire can no longer
be ignored. If this occurs, the effects from lead wire resistance can be alleviated and the
desired voltage can be applied to the DUT by selecting the four-terminal connection and
connecting the SENSE terminal near the DUT.
Offset Calibration
(See section 5.9 for the procedure)
If offset calibration is executed, the measurement function of the GS820 is used to
correct the zero point offset of the source level. For example, this function is used
to correct the offset fluctuation that results when the ambient temperature changes
drastically. However, because measurements are performed to calibrate all the ranges,
the source and measurement operations are suspended for a few seconds while the
calibration is in progress.
