Digital multimeter True RMS

A multimeter is a meter that allows the measurement of electrical quantities.

This meter allows you to measure AC and DC voltage, current and resistance, capacitance, frequency and temperature. In addition, this multimeter is equipped with a test slot for checking transistors and can also test diodes at the same time. Switching between individual types of measurement is done using a rotary selector, where the desired range for individual quantities can also be set.

The measured values are displayed on the clear, backlit LCD display of the durable, plastic body of the device. In addition, the body is placed in a removable silicone cover, which provides partial protection from moisture, dirt and, last but not least, protects the device from vibrations. Quality cables with measuring tips are included with the meter.

The recommended alkaline battery 9V 6F22 takes care of the power supply. The device is equipped with a 10 A fuse.

TRUE RMS - a meter with this function calculates the true rms value of alternating current and voltage for both sinusoidal and non-sinusoidal waveforms. The device first measures the actual value of the sine wave in several time intervals, then performs the square of the measurement results, adds them, calculates the average, and finally powers the result of the average. The result of the measurement is the actual rms value of the AC voltage/current even for a distorted sine wave or square wave.
