The analog multimeter MX 1 from Metrix is a robust measuring instrument for use in electrical installations up to category CAT III 600 V according to IEC/EN 61010-1 edition 2. It features a spray-water-protected housing with a soft protective sleeve, making it suitable for various operating conditions. The IP65 protection rating ensures dust and spray water protection, making the device suitable for use outdoors or in humid environments. The MX 1 is protected in all measurement ranges and includes a safety alarm that is triggered when voltage is detected during ohmmeter operation, minimizing the risk of incorrect measurement or electric shock.

Applications
This multimeter is designed for use in electrical installations corresponding to safety category CAT III 600 V. This typically includes installations in buildings, such as distribution boards, wiring, and electrical equipment operated at a nominal voltage up to 600 V. Its robust construction makes it particularly suitable for use in the trades, during maintenance work, or in industrial environments where high mechanical loads and environmental influences occur.

Functions and Equipment in Detail
The MX 1 offers a wide range of measurement functions: it can measure direct voltage from 150 mV to 1500 V and alternating voltage from 5 V to 1500 V. Alternating voltage measurement is performed as average value measurement, which is typical for analog multimeters. The bandwidth ranges from 16 Hz to 1 kHz. For current measurements, ranges from 50 µA to 10 A (direct current) and 500 µA to 10 A (alternating current) are available. The resistance range extends from 20 kΩ to 2 MΩ. Additionally, the device offers a continuity test with acoustic alarm, a diode test, and a dB measurement function in the range of -6 to 66 dB. The basic accuracy is class 2, which is typical for analog measuring instruments in this segment.

Technology Explained Simply
The analog display of the MX 1 operates with a movable pointer that indicates measured values on a scale. The scale is divided into various ranges, with accuracy being lower near the zero point than in the middle of the scale. The IP65 protection rating means the device is protected against dust and spray water, making it suitable for use in humid or dusty environments. The CAT III 600 V category refers to the safety standard for measuring instruments that may be used in electrical installations with a maximum voltage of 600 V. The integrated safety function during ohmmeter operation warns of present voltage to avoid accidental measurements under voltage.

Compatibility and Accessories
The MX 1 can be combined with various accessories suitable for measurements in electrical installations. These include test leads with 4 mm connectors (straight and angled), rated for CAT IV 1000 V, as well as test probes and crocodile clips in various designs. Special clamps such as the MN08 DA 200/0,2 or the C100 DA 1000/1 are also available for specific measurement tasks. A tool kit for electricians is also available.

Mounting and Installation
The multimeter is used without additional mounting or installation. It is handheld and operated via a rotary knob to select measurement functions and ranges. The test leads are inserted into the corresponding sockets on the device. Use is direct at the measurement object, with compliance required with the safety regulations of standard IEC/EN 61010-1 edition 2.

Advantages in Operation
The MX 1 offers high mechanical robustness and is designed for use under harsh conditions. The IP65 protection rating protects against spray water and dust, extending the device's service life. The integrated safety function during ohmmeter operation increases operator safety. The analog display allows for quick visual assessment of measurement values, especially during continuous measurements. The device is lightweight (420 g) and compact (155 x 98 x 40 mm), facilitating handling.
