If a digital multimeter displays 0000 when reading amperage what should the technician do to get a more accurate reading?

If a digital multimeter displays 0000 when measuring amperage, the technician should first check the meter's settings to ensure it's configured for the correct measurement type and range. Next, they should confirm that the test leads are properly connected and that the circuit is active, as an open circuit or a blown fuse could also result in a zero reading. If everything appears correct and the meter still reads 0000, the technician may need to test the multimeter on a known live circuit to rule out a faulty meter.
