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:
