Multi-Function Meter Of Electrical System Parameters

Keep up to date with products in the category

  • Professional and versatile

    The multifunctional meter of parameters of electrical installations Sonel MPI-530 is used for precise measurements of electrical installations. The device has been constructed in compliance with the requirements of EN 61557 standard. It makes it possible to carry out all measurements connected with protection against electric shock described in the HD 60364-6 standard.

    The Sonel MPI-530 specialised meter is distinguished by extensive ground measurement functions - additional clamp methods and soil resistivity. Using the optional AuroISO-1000C adapter, automatic insulation resistance measurements are also possible in sockets and for 3-, 4- and 5-core cables.

    With the use of the Sonel MPI-530 meter it is also possible to test the illumination intensity. An additional external probe is required for this purpose. The instrument can record and analyse network parameters - including harmonics up to 40th. Another advantage of the meter is the robust IP54 casing, which protects the device from mechanical damage, dust or splashing.

    Features

    The meter offers a wide range of functionalities. It combines the measuring capabilities of several devices, while ensuring equally good accuracy.

    • MPI-530 can be used for all measurements for commissioning of electrical installations in accordance with applicable regulations:
      • short circuit loop impedance (also in circuits secured with RCDs),
      • RCD parameters, » insulation resistance,
      • earth resistance (4 measurement methods + soil resistivity measurement),
      • continuity of protective and equipotential bondings,
      • light intensity measurement,
      • phase sequence test, » motor rotation direction test.
    • MPI-530 can record 50/60 Hz power quality parameters:
      • voltage L1 – average values in the range up to 500 V,
      • L1 current – average values, current measurement in the range up to 3 kA (depending on the current probes used),
      • frequency in the range of 40 Hz – 70 Hz,
      • active (P), reactive (Q) and apparent (S) power,
      • power factor (PF), cosφ,
      • harmonics (up to 40th for voltage and current),
      • total harmonic distortion (THD) for current and voltage.

    Inspection of electrical safety

    This device may be used to inspect safety of electrical systems in households and industrial facilities. Measurements can be easily automated with:

    • auto mode of residual current devices (RCD) tests,
    • the WS adapter that can be used for testing systems via standard 230 V sockets,
    • AutoISO-1000C adapter for automatic insulation resistance test of 3-, 4- and 5-conductor cables, without switching.

    Memory structure

    The memory structure has a tree form. It has the ability to store tens of thousands of results in the configuration of CLIENT-OBJECT-FACILITY-MEASURING POINT, which helps to create a clear test protocol during later stages. This structure may be prepared in the meter, before starting the work. Entering data into the device is facilitated by QWERTY keyboard with Bluetooth communication module.

    Built-in help system

    The device has built-in help screens with measurement diagrams. Thanks to this you can easily and quickly check and make sure how to connect to a given system depending on the type of performed measurement.

    Increased resistance to environmental conditions

    The MPI-530 meter will cope well in difficult environmental conditions. Protection against penetration of dust and water is ensured by a unique housing with a level of protection IP54. It is resistant to mechanical damage, and a special design allows you to easily protect the screen by shielding using the cover of the meter. In addition to the fact that it protects against damage, it also allows you to conveniently carry and use the device in different positions.

    Communication and software

    You can easily transfer measurement data to your computer via USB port or Bluetooth wireless communication. In order to generate a report on measurements for electric shock protection, use Sonel Reports PLUS software. Saving the downloaded data to the simplest formats and printing is provided by free Sonel Reader software
