Resistance Measurement Configuration
The meter can make 2-wire or 4-wire ohms measurements. The meter
can compensate for voltages in the resistive circuit being measured using
offset compensation.
You can also choose to either limit the power applied
or limit the open circuit voltage applied during a resistance
measurement.
The test current sourced by the meter depends upon the range and
conditions as shown below:
