Metravi 23S-TRMS Digital TRMS Multimeter

A. Product Overview

The Metravi 23S-TRMS Digital TRMS Multimeter is a professional auto-ranging digital multimeter suitable for accurate electrical and electronic measurements. It comes with a 20,000 count display, 4-1/2 digit resolution and True RMS measurement for voltage and current, making it useful for both general and advanced testing applications.

The meter includes a large 21 mm character height backlit LCD display, which helps users read measurements clearly in low-light working areas. It also has a dual display feature that can show frequency and voltage on the same screen, making it practical for troubleshooting electrical signals.

It supports measurement of DC voltage up to 1000V, AC voltage up to 750V, AC and DC current up to 10A, resistance up to 20MΩ, capacitance up to 2000µF, frequency up to 20MHz and temperature from minus 20°C to 1000°C. It also includes diode testing, continuity testing and non-contact voltage detection.

B. Working Principle

The Metravi 23S-TRMS works by converting electrical signals into digital readings using double integral A to D conversion. This method helps provide stable and reliable measurements for voltage, current, resistance and other parameters.

For AC measurement, the meter uses True RMS technology. True RMS measurement calculates the effective value of an AC signal more accurately, especially when the waveform is not a perfect sine wave. This makes the meter more dependable for testing modern electrical systems, variable frequency drives, power supplies, control panels and industrial equipment.

For resistance, capacitance, diode and continuity testing, the meter sends a small internal test signal through the component and displays the measured value. For temperature measurement, it uses a K-type thermocouple. For NCV testing, the meter detects the presence of an electromagnetic field and gives a buzzer indication, with the buzzer response increasing as the field intensity increases.

C. Why It Is Used

The Metravi 23S-TRMS Digital TRMS Multimeter is used to test, diagnose and maintain electrical and electronic circuits. It is suitable when users need accurate readings for voltage, current, resistance, capacitance, frequency and temperature.

It is used for checking power supply output, control panel wiring, electrical circuits, industrial machines, electronic components, batteries, continuity faults, diode condition and live voltage presence. Because it has True RMS measurement, it is especially useful where AC signals may be distorted or non-linear.
