How do you use a manual electrical tester?

The video, titled "Basic Electrical Testers & HOW TO USE THEM," begins with the narrator instructing viewers to set up the electrical tester in front of them. The focus is on demonstrating the proper usage of essential electrical testing equipment.

As the demonstration commences, the narrator advises viewers to pull out the two leads attached to the tester. This is a crucial step in preparing the device for use, ensuring that both leads are accessible and ready for connection.

The next step involves accessing the selector knob on the tester. The narrator emphasizes the importance of turning this knob to the "voltage" setting, as this prepares the tester to measure the electrical potential difference between two points.

With the selector knob set to voltage, the narrator proceeds to show how to connect the leads. One lead is attached to the first point of measurement, while the other lead is connected to the second point. This establishes a complete circuit for the tester to measure.

The video continues with the narrator highlighting the importance of ensuring proper lead placement and maintaining a SAFE distance from live electrical sources while performing the test. Safety precautions are emphasized throughout the demonstration.
