Simplicity and cutting edge technologies. Sonel MPI-506 is probably the world's smallest meter with such a large number of measurement functions. 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 backlight, which significantly improves operation in low light. Large memory eliminates the need for taking notes during the measurements.
This device may be used to inspect safety of electrical systems in households
and industrial facilities. Its main advantage is quick measurement (just a few
seconds!) of fault loop impedance in circuits with RCD.
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.
