The Metrix MX0675 is a TRMS AC/DC multi-function clamp meter that combines the functions of a digital multimeter with those of a current clamp. It enables precise measurements of alternating and direct current up to 1000 A (AC) or 1400 A (DC), as well as voltage, resistance, frequency, and temperature. The clamp is designed for use in electrical installations, particularly in environments with high safety requirements, and offers a safety category of 600 V CAT IV / 1000 V CAT III, making it suitable for measurements in distribution systems and on main lines.

Applications

The MX0675 is suitable for professional applications in electrical contracting, industry, and maintenance of electrical installations. It is particularly used where simultaneous measurements of current and voltage are required, for example, in diagnosing network fluctuations, checking loads, or analyzing electrical consumers. The high safety category allows use in distribution systems up to 600 V CAT IV, enabling measurements on main lines and meter connections.

Functions and Equipment in Detail

The clamp features a dual display with 10,000 points, which simultaneously shows two measurement values – for example, current and voltage – thereby increasing measurement efficiency. The display is backlit, ensuring readability even in poor lighting conditions. The TRMS measurement ensures accurate values regardless of signal shape, which is especially important for non-sinusoidal loads such as frequency converters or electronic consumers. Basic functions include measurement of alternating and direct voltage (up to 1000 V AC / 1400 V DC), alternating and direct current (up to 1000 A AC / 1400 A DC), resistance (up to 10 kΩ), frequency (up to 10 kHz), and temperature (with K-type thermocouple, range -40.0 °C to 1200 °C). Additional functions include an audible continuity test, diode test, HOLD, PEAK, MAX/MIN, and Δ-Zero DC.

Technology Explained Simply

Measurement is performed via a Hall sensor, which measures the magnetic flux around the conductor to determine the current. This enables contactless measurement without interrupting the circuit. The clamping opening of 40 mm allows measurement of conductors with a diameter up to 40 mm, which is sufficient for many industrial and craft applications. TRMS technology (True Root Mean Square) calculates the effective value of current or voltage, regardless of signal shape, resulting in more accurate results than RMS or peak measurements for non-sinusoidal signals.

Compatibility and Accessories

The MX0675 can be extended with various accessories available in the range. These include test leads with 4 mm connectors (straight and angled), test probes, crocodile clips, and an accessory set for electricians. These components are designed for use with CAT IV and CAT III safety categories and support measurements on various contacts and conductors.

Mounting and Installation

The clamp is simply closed around the conductor to be measured. Measurement is contactless, so no interruption of power supply is required. Operation is via buttons on the device, which select the various measurement functions. The display shows the measurement values directly, with the dual display showing two values simultaneously. The instruction manual, included in the delivery, describes the functions and correct handling.

Operational Advantages

The simultaneous display of current and voltage on the dual display reduces measurement time and increases efficiency. TRMS measurement ensures high accuracy, even with complex signals. The high safety category allows use in critical system areas. The large, backlit display improves readability, and integrated functions such as HOLD or MAX/MIN support documentation of measurement values.
