Details
This command determines if 2-wire (local) or 4-wire (remote) sensing is used.
When you use 4-wire sensing, voltages are measured at the device under test (DUT). For the source
voltage, if the sensed voltage is lower than the programmed amplitude, the voltage source increases
the voltage until the sensed voltage is the same as the programmed amplitude. This compensates for
IR drop in the output test leads.
Using 4-wire sensing with voltage measurements eliminates any voltage drops that may be in the test
leads between the Model 2461 and the DUT.
When you are using 2-wire sensing, voltage is measured at the output connectors.
When you are measuring resistance, you can enable 4-wire sensing to make 4-wire resistance
measurements.
When the output is off, 4-wire sensing is disabled and the instrument uses 2-wire sense, regardless of
the sense setting. When the output is on, the selected sense setting is used.
Example
VOLT:RSEN ON
Set the remote sense for voltage
measurements.
