Digital Multimeter (DMM)

A digital multimeter is a versatile tool that can measure various electrical parameters, including voltage, current, resistance, and more. While not exclusively a voltage tester, it's commonly used for voltage testing by selecting the appropriate mode on the device.

Circuit Testers

These are more advanced tools that can not only detect voltage but also provide additional information about the circuit, such as the type of voltage (AC or DC), polarity, and continuity. They often have multiple functions and display options.

How to use voltages testers safely?

When using voltage testers, it's important to follow safety guidelines:

• Always assume that a circuit is live until proven otherwise.
• Use proper personal protective equipment (PPE) such as gloves and safety glasses.
• Choose the appropriate voltage tester for the type of voltage (AC or DC) you're dealing with.
• Make sure the tester is working correctly before each use.
• Verify the tester on a known live circuit before testing an unknown one.
• Keep your fingers behind the tool's insulated portion while testing to avoid accidental contact with live parts.
• If you're not familiar with electrical work, consider seeking assistance from a qualified electrician.

Remember, safety should always be the top priority when working with electricity.
