Switch on the multimeter, and using the dial on the front, select the resistance function. The multimeter will have two probes with metallic pointed ends. Place the probes on either side of the earth wire. The display on the multimeter should show a low resistance of approximately 0.5 Ohms. If the resistance is significantly higher than this, the wire is faulty and needs to be replaced.
