What is the highest category of meter?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (C)

Meters are assigned categories that indicate the level of safety protection and the environments in which they can be used. The higher the category, the greater the protection against voltage transients and the more robust the meter’s insulation and design. In this set, the categories shown ascend in protection level, and the highest one listed represents the greatest capability within the options. That’s why it’s the best answer: it denotes the most demanding, yet standard, category available among the choices. Lower categories are suitable for less demanding situations but don’t represent the maximum shown here.
