Sonel MPI-502 Multifunctional Electrical Installations Meter
Description
Professional measurements in the simplest form
The multifunctional meter of electrical installation parameters Sonel MPI-502
is a compact meter of electrical installation parameters, equipped with a
number of practical functions. The MPI-502 model is a successor of the popular
and valued among professionals Sonel MIE-500 meter, which was mainly used for
measurements of installations protected with over-current and residual current
devices in different types of networks.
The Sonel MPI-502 meter is one of the smallest multifunctional measuring
instruments on the market. Despite its compact size, the device offers a wide
range of functions and is distinguished by its ergonomic design and very
robust casing. Another advantage of the device worth mentioning is the
extremely simple operation, which, combined with the easy-to-read, backlit
display, ensures high comfort of use.
Features
- Measurement of short circuit loop parameters
- Measurement of short circuit loop impedance in networks with rated voltage: 220/380 V, 230/400 V, 240/415 V and frequency 45…65 Hz, operating voltage range: 180…460 V Indication of short circuit loop resistance R and short circuit loop reactance X
- Measurements of short circuit loop impedance with 15 mA current, without tripping the RCD circuit breaker
- Maximum test current: 7.6 A (at 230 V), 13.3 A (at 400 V)
- Testing RCD breakers of AC, A types
- Testing of prompt, short-delay, and selective RCDs with rated current values 10, 15, 30, 100, 300, 500 mA

- Backlit keypad
Simplicity included in the price
Features of MPI-502 are focused on ergonomics and maximally simplified user
experience. The functions are selected with a rotary switch. Additional
parameters are set with buttons located on the housing face. The settings are
saved by the device even when the battery is completely discharged.
All buttons and the modular display have a backlight, which significantly
improves operation in low light. Large memory eliminates the need for taking
notes during the measurements.
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.
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 IP67.
Communication and software
You can easily transfer measurement data to your computer via 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.
