Details
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.
For 4-wire resistance measurements, when offset compensation is enabled, the measure range is
limited to a maximum of 100 kΩ. Offset compensation is automatically enabled when dry circuit is
enabled.
For 2-wire resistance measurements, offset compensation is always set to off.
For temperature measurements, offset compensation is only available when the transducer type is
set to 3-wire or 4-wire RTD.
Example
*RST
:SENS:FUNC "FRES"
:SENS:FRES:RANG 10e3
:FRES:OCOM ON
:COUNT 5
:TRAC:TRIG "defbuffer1"
:TRAC:DATA? 1, 5, "defbuffer1", READ
Reset the instrument.
Set the measurement function to 4-wire
resistance and set the range to 10 kΩ.
Turn offset-compensated ohms on.
Set the measurement count to 5.
Make measurements and store them in
defbuffer1.
Retrieve the measurement values for
readings 1 to 5.
