Multi-meter
A multi-meter, also known as a volt-ohm meter (VOM), is a versatile electronic device that measures multiple electrical properties such as voltage, current, and resistance. It can be used to troubleshoot a wide range of electrical problems in various settings, such as homes, automobiles, and industrial facilities.
Oscilloscope
How do you test and troubleshoot complex electrical circuits when you need to monitor a signal over time? This is when you set aside your multimeter and pull out an oscilloscope!
