What type of multimeter is best for measuring high voltage?

A True RMS digital multimeter is designed to provide accurate measurements of both AC and DC voltages, particularly in circuits with non-linear loads where the waveform may not be a pure sine wave. In high voltage applications, the true RMS function ensures that the multimeter can effectively measure and display accurate voltage readings by taking into account the actual shape of the waveform. This feature is crucial for electrical systems that often experience variations in voltage due to harmonics or other distortions.

Additionally, True RMS multimeters typically have higher voltage ratings and improved safety features, making them suitable for high voltage environments. They can withstand the electrical stress that comes with measuring higher voltage levels, thereby ensuring user safety while providing reliable readings. This makes them the preferred choice for electricians and technicians when dealing with high voltage measurements, compared to analog or basic digital multimeters, which might not deliver the same level of accuracy and safety in such scenarios.
