4.2 Selecting the Wiring System (Remote Sense or
Local Sense)
Procedure
1.
Press
UTILITY
to display the following menu.
2.
Press the
Wire
soft key to select 4W or 2W.
Explanation
There are two methods for connecting the GS200: 2W and 4W.
2W: Two-terminal connection (local sense)
4W: Four-terminal connection (remote sense)
The connection diagrams are given on the next page.
Note
The four-terminal connection does not function for the 10 mV and 100 mV ranges in voltage
source mode. You must use the two-terminal connection instead.
WARNING
• When making a four-terminal connection, be careful that the connection to
the SENSE terminals does not get cut. If the voltage is not sensed correctly,
abnormal voltage may appear across the OUTPUT Hi and OUTPUT Lo
terminals.
• When making a two-terminal connection, use the OUTPUT terminals. If the
SENSE terminals are used, the GS200 will be prohibited from generating the
correct output, and it may be damaged.
When the GS200 is measuring voltage in current source mode and the current becomes
large, the voltage drop in the lead wire can no longer be ignored. In such a case, you
can measure the voltage with reduced effects of the lead wire resistance by selecting the
four-terminal connection (4W) and connecting the SENSE terminals near the DUT. The
effects of the lead wires also appear in voltage source mode. In this case as well, using
the four-terminal connection (4W) enables the GS200 to apply the specified voltage to
the DUT with reduced effects of the lead wire resistance.
