Resistance Measurement
Resistance Measurement
B2900 supports resistance measurement. If the measurement parameter is set to
resistance OHMS (R), the source/measure unit (SMU) automatically sets the current
source and voltage measurement operation to perform resistance measurement.
For performing accurate measurement, B2900 provides the compensation function.
NOTE
To Enable Resistance Measurement
The resistance measurement operation must be specified. See
"Range parameters"
on page 4-12
and
"To Enable Resistance Measurement" on page
5-22.
In the initial setting, the resistance measurement operation is set to OFF.
Resistance Compensation
Resistance compensation (R Compen) is effective for performing low resistance
measurements accurately. If R Compen is set to ON, the channel performs
measurement twice and returns the compensated measurement result given by the
following formula. This technique is effective for reducing the thermal EMF.

To enable resistance compensation, press the Config > Measure > R Compen > ON
function key on a 1-channel model, or the Config > Measure > R Compen > ALL or
Ch 1 or Ch2 > ON function key on a 2-channel model.
To disable resistance compensation, press the Config > Measure > R Compen >
OFF function key on a 1-channel model, or the Config > Measure > R Compen >
ALL or Ch 1 or Ch2 > OFF function key on a 2-channel model.
