We can test the points on the PCB using a Multimeter to confirm whether current is arriving or not. But this handy tester will give an Audio visual indication. It beeps and lights LED when there is current flow in the test points. It can also be used as a Battery tester. If more than 2V is present in the battery, buzzer beeps and LED lights. If the battery is flat, the tester remains silent.It is a good tool, so learn to build this as your start up project.
