ESC
• To exit the menu during operation, press
ESC at the upper left of the operation
panel.
• In the procedural explanation below, the
phrase “
rotary knob, numeric keys, <,
and > ” are used to refer to the operation
of selecting or setting items or entering
values using the
rotary knob , numeric
keys
, , and keys (BS key and
right arrow key). For details on the
operation using the rotary knob, numeric
keys, , and , see sections 3.8 or
3.9.
Selecting the Connection Type (Remote Sense or Local Sense)
1. Press MISC to display the MISC menu.
2. Press the Wire soft key to select 4W or 2W. If you select 4W, the remote sense
indicator (4WIRE) at the left of the display illuminates.
Explanation
The GS610 has two types of sensing, 2W and 4W.
2W:
Two-terminal connection (local sense)
4W: Four-terminal connection (remote sense)
The connection diagrams are given on the next page.
If the current flowing through the Hi and Lo terminals is small, select two-terminal
connection (2W). When the output current is large, a voltage error occurs between the
Hi and Lo terminals that are being sensed due to the effects of the lead wire resistance.
In such case, select four-terminal connection (4W) and connect the measurement lead
from the SENSE terminal close to the DUT. This enables the voltage to be sensed with
the effects of the lead wire resistance reduced. This function is effective when the
current is large and the voltage appearing at the DUT is small such as in a low
resistance measurement.
Note
When making a four-terminal connection, be careful that the connection to the SENSE
terminal does not get cut. If it does, an error occurs in the voltage between the Hi and Lo
terminals, because the voltage is not sensed correctly.
When making a two-terminal connection, use the OUTPUT terminals. If the SENSE terminal
is used, the GS610 cannot generate the voltage or current correctly and can cause a
malfunction.
