6-wire ohms measurements
The 6-wire ohms measurement configuration allows you to make accurate resis-
tance measurements on resistor networks and hybrid devices in cases where
internal resistance connection nodes are not accessible. The combination of 4-
wire Kelvin connections and guarded ohms features eliminates the effects of inter-
nal parallel resistances that could degrade measurement accuracy and reduce
measurement speed. The basic procedure for setting up the SourceMeter for 6-
wire ohms measurements is covered below.
NOTE See Figure 2-5C for 6-wire ohms connections. See also Section 2,
“Ohms guard,” and Section 6, “Guard.”
1. Press CONFIG then Ω to display the CONFIG OHMS menu.
2. Select SENSE MODE, then press ENTER.
3. Select 4-WIRE, then press ENTER.
4. From the CONFIG OHMS menu, select GUARD, then press ENTER.
5. Select OHMS, then press ENTER.
6. Press EXIT to return to normal display.
7. Press MEAS then Ω to select the ohms measurement function.
8. Select the appropriate measurement range, or use autoranging if desired.
9. Turn on the output by pressing the ON/OFF OUTPUT key.
10. Take readings from the display.
11. Turn the output off when done by pressing the ON/OFF OUTPUT key.
