What type of meter is commonly used to measure electrical voltage?

• A. Analog meter
• B. Digital multimeter
• C. Clamp meter
• D. Amperemeter

Answer: (B)

A digital multimeter is widely recognized for measuring electrical voltage due to its versatility and precision. This tool can measure not only voltage but also current and resistance, making it an essential instrument for HVAC technicians and electricians. The display of a digital multimeter provides clear numerical readings, which can be easier to interpret compared to analog meters that require the user to read a needle against a scale. The digital multimeter operates by using an internal analog-to-digital converter, allowing it to provide accurate voltage readings in various formats, including AC and DC voltage. Additionally, it often features various settings and ranges, allowing users to select the appropriate measurement level for their needs. While analog meters can also measure voltage, they can be less intuitive to read and may introduce parallax errors when interpreting the needle position. Clamp meters are specifically designed for measuring current rather than voltage, and amperemeters are used to measure electricity flowing through a circuit, which does not encompass measuring voltage directly. Hence, the digital multimeter stands out as the most common and effective tool for measuring electrical voltage in the HVAC field.
