Multifunctional meter for electrical installation parameters MPI-535 WMPLMPI535

Multifunctional installation electrical parameter meter

The Sonel MPI-535 meter is an advanced device designed for comprehensive analysis of electrical installations, both in residential and industrial buildings. It allows a series of measurements to be performed, which verify the safety and proper functioning of the system. This makes it indispensable for installers, service technicians and people responsible for maintaining the electrical efficiency of facilities.

Functionality and application

The device combines the functions of many specialized meters, offering a wide range of measurements: loop impedance, earth resistance, residual current device (RCD) parameters, insulation resistance, and phase sequence testing. This makes it possible to perform a complete installation review in accordance with applicable standards and regulations. Measurement automation, including RCD testing in Auto mode and pre-programmed measurement sequences (autotests), significantly speeds up and simplifies work. In addition, the ability to expand sequences with your own procedures provides flexibility and adaptation to individual needs.

Key features and benefits

• Versatility: One meter replaces several specialized devices, which translates into cost and space savings.
• Automation: Auto function and autotests simplify the measurement process and minimize the risk of errors.
• Intuitive operation: A large, 7” touchscreen LCD with high resolution provides comfortable use and easy reading of results. The included stylus allows operation even with dielectric gloves.
• Built-in help system: Help screens with measurement diagrams make it easier to connect the device correctly and interpret the results.
• Durable construction: A housing with an IP51 degree of protection ensures resistance to dust and water, as well as mechanical strength.
• Communication and data storage: The ability to transfer data via USB, microSD card and wireless communication (Bluetooth, Wi-Fi) enables easy report creation and archiving of measurement results.
• Wide RCD measurement range: Support for RCDs of type A, AC, B, B+, F and EV allows for a comprehensive analysis of protection against electric shock.
• Earth resistance measurement: Available 3- and 4-wire methods and 2-clamp method provide accurate results in various conditions.

Technical parameters – what you should know

The MPI-535 meter offers precise measurements thanks to advanced technology. It has a wide measurement range for loop impedance (0.13 Ω…1999.9 Ω), insulation resistance (50 Ω…2 GΩ) and earth resistance (0.50 Ω…1.99 kΩ). The device meets the requirements of measurement category CAT III 500 V and CAT IV 300 V, which guarantees safety of use in various working environments. Additionally, the meter has a function for RCD analysis and testing of residual current devices with an increasing leakage current value, which allows for an accurate assessment of their operation under various load conditions.
