What a role does a electrical testing tool play?

Testing is an important part of the design and production process for any electromechanical device. In addition to understanding the basics of electrical testing tools, these devices need to be tested to ensure that electricity is flowing where it should be, and is not where it shouldn’t. With electrical design, designers need to be worried about safety of the user because the voltages and currents can be very high. With electronics, one is really just worried about the safety of the circuitry. The voltages typically aren't high enough to be dangerous. Thankfully, it’s fairly simple to test circuitry if you’re equipped with a little know-how and the right tools. Read on to learn simple ways to conduct electrical testing, and to incorporate this into the overall production process.

Basic testing procedures typically involve anything you can do with a digital multimeter, such as:

- measure voltage

- measure current

- measure resistance

- measure capacitance

- check continuity

Multimeters are typically your first stop on the troubleshooting train. They are useful to diagnose circuitry and to gather simple information like the characteristics mentioned above. Thankfully, they are easy to find, and reasonably cheap. Some other useful tools for basic testing are those that enable you to check power supply (older models are analog; new ones are digital) - these allow you to set a specific voltage and/or current value and operate your circuit at those levels. An outlet monitor is also a good tool to have. They plug into the wall and then you plug your device into it. The monitor will tell you what voltage, current, wattage, etc. you are operating at. This information is good for determining how much it will cost you to operate a given device.
