Multifunction meter of electrical installation parameters with a Calibration Certificate WMPLMPI506

Sonel MPI-506 is a multifunction meter of electrical installation parameters. It is one of the smallest devices in the world with so many measuring functions at the same time.
Small dimensions, ergonomics and convenient operation while maintaining versatility and versatility in use are the distinguishing features of the device.
MPI-506 we will perform the following measurements (in accordance with PN-EN 61557):

fault loop impedance (also in circuits with RCDs)
RCD parameters
insulation resistance
continuity of protective and equipotential bonding
phase sequence test
