Certain HIOKI Digital Multimeters also provide True RMS measurement, high resolution displays, low pass filter functions and enhanced safety features for professional electrical environments.

B. Working Principle

A HIOKI Digital Multimeter measures electrical signals through its test terminals and converts the detected electrical value into a digital reading.

For voltage measurement, the multimeter is connected across two points in the electrical circuit. The instrument measures the potential difference and displays the corresponding voltage.

For current measurement, the meter is connected according to the specified measurement method so that electrical current can be measured safely.

For resistance measurement, the multimeter applies a small internal test signal to the component or circuit and calculates resistance based on the measured response.

True RMS models calculate the effective value of AC signals, which helps provide accurate measurements even when the waveform is distorted or non sinusoidal.

The processed measurement is displayed digitally, allowing technicians and engineers to quickly evaluate the condition of electrical circuits and equipment.

C. Why HIOKI Digital Multimeters Are Used

HIOKI Digital Multimeters are used because electrical systems require accurate and reliable measurement during installation, commissioning, troubleshooting and preventive maintenance.

They help users:
