To test a fuel sending unit with a multimeter, first set the multimeter to measure resistance (ohms). Disconnect the sending unit from the fuel tank and connect the multimeter probes to the sending unit terminals. As you manually move the float arm, observe the multimeter reading; it should change smoothly, indicating varying resistance without any sudden drops or spikes, which would suggest a fault.
