The front-panel display will look similar to the following example.
Figure 71: Resistance measurement with automatic settings
Offset-compensated ohms
The voltage offsets caused by the presence of thermoelectric EMFs (V
EMF
) can adversely affect
resistance measurement accuracy. To overcome these offset voltages, you can use offset-
compensated ohms.
See Offset-compensated ohm calculations (on page 4-21) for additional detail on calculating
offset-compensated ohms.
Setting offset-compensated ohms
Using the front panel:
This setting is only available from the front panel when the resistance measurement function is
selected.
1. Press the MENU key.
2. Under Measure, select Settings.
3. Next to Offset Compensation, select On.
4. Select HOME to return to the operating display.
Using SCPI commands:
To enable offset-compensated ohms, send the command:
SENSe:RESistance:OCOMpensated ON
Using TSP commands:
To enable offset-compensated ohms, send the commands:
smu.measure.func = smu.FUNC_RESISTANCE
smu.measure.offsetcompensation = smu.ON
