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.
Set up the measurement from the front panel
To set up the application from the front panel:
1. Make connections from the Model 2460 to the device under test, as described in Device
connections (on page 5-2, on page 8-2).
2. Reset the instrument:
a. Press the MENU key.
b. Under System, select Manage.
c. Select System Reset.
d. Select OK.
3. Press the FUNCTION key.

5. Press the HOME key.
6. In the SOURCE CURRENT area, select the button next to Source. Select the source value.
7. Press the MENU key. Under Measure, select Settings.
8. For Sense Mode, select 4-Wire Sense.
9. Next to Offset Comp, select On.
10. Press the HOME key.
11. Press the OUTPUT ON/OFF switch to enable the output and start making measurements.
12. Press the OUTPUT ON/OFF switch to disable the output and stop making measurements.
The instrument displays the measurements in the MEASURE VOLTAGE area of the Home screen.
