MPI-525

Multi-function meter of electrical system parameters

Features

The meter offers a wide range of functionalities. It combines the measuring capabilities of several devices, while ensuring equally good accuracy. The device 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 (3-pole method),
• continuity of protective and equipotential bondings,
• phase sequence test

Additional functions

• Checking the correctness of PE connection using a contact electrode.
• Measurement of voltage (0 … 500 V) and network frequency.
• Memory of 990 results.
• Wireless data transmission to a computer.

Testing the insulation with a voltage of 2.5 kV

The unique feature of the meter is the option of measuring the insulation resistance with a voltage of 2500 V. Moreover, with AutoISO-2500 adapter, the user may check R_ISO of 3-, 4- or 5-wire conductors and cables.

The device has a built-in timer. It may be used to set three different periods for measurements and result read-outs (in the range of 1...600 s). It also automatically calculates two absorption coefficients.

In order to ensure safety of the user, after the measurement completion or interruption, the device automatically unloads the tested object.

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,
• AutoISO-2500 adapter for automatic insulation resistance test of 3-, 4- and 5-conductor cables, without switching

Increased resistance to environmental conditions

The 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 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.
