Handheld digital multimeters enable accurate measurement of AC/DC voltage and current, resistance and, depending on the model, also frequency, capacitance, temperature or 4–20 mA current loops. The range includes professional multimeters from Hioki, including clamp meters, earth testers, voltage testers and phase detectors. They are characterized by high accuracy, fast response, rugged design and a strong focus on safety in accordance with relevant CAT categories. Individual models differ in their range of functions, input protection level and data communication capabilities.
