Low-resistance measurements
This application demonstrates how to use the Model 2460 to measure a low-resistance device. You
can measure from the front panel or over the remote interface using SCPI code or TSP code.
For this application, you will:
•
Reset the instrument.
•
Select the source current and measure resistance function.
•
Set the current source value.
•
Select four-wire (remote sense) mode. This eliminates the effect of lead resistance on
measurement accuracy.
•
Enable offset compensation. This reduces offset caused by thermoelectric voltages. For
information about offset compensation, see "What is offset compensation?" in the
Model 2460
Reference Manual
.
•
Turn on the source output and start making measurements.
•
Generate readings from the front panel or the remote interface.
•
Turn the source output off.
