What to do if the digital multimeter is faulty?

If a digital multimeter is faulty, start by checking the battery, inspecting the test leads for damage, and confirming the fuse inside the meter is intact. If it still gives incorrect readings, stop using it immediately and have it calibrated or repaired by a qualified technician. In many cases, replacing the unit is safer and faster.
