Resistance Measurement
Resistance Measurement
B2961A/B2962A supports resistance measurement. If the measurement parameter
is set to resistance OHMS (R), B2961A/B2962A automatically calculates resistance
value from measured voltage and current.
For performing accurate measurement, B2961A/B2962A provides the
compensation function.
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.

where, V

is the measurement results at the 0 A source condition, and I

is the
measurement results at the 0 V source condition.
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.
