Sonel MPI-540 Multifunction Tester - CAT IV

Multifunction Installation Tester with Power Quality Analyser and Ground Resistance Testing

Much more than a Multifunctional Meter

The largest 7" touch panel on the market - remarkable ergonomics and ease of use
Removable memory card - easy increase of memory capacity
Measurement of all parameters related to earthing and protection against electric shock - one device instead of several
Li-Ion battery - longer operation of the meter
The ability to add a voice memo or photo for measurement - a multimedia description of the measurement site
Auto-tests - the ability to perform automatic measurements in sequence * - simplified measurements
Fast path from measurements to report - saves time
Three-phase power network data logger - basic power quality diagnostics
Real time display of network parameters - immediate evaluation of the tested device
Quick measurement of the short circuit impedance with the RCD without triggering (up to several seconds) – time saver
Parameters measured in accordance to class S of EN 61000-4-30 standard - high accuracy of measurements
Energy calculator* - quick evaluation of potential savings


This device can be used for all measurements for commissioning of electrical installations in accordance with applicable regulations:
Short circuit loop impedance (also in circuits with RCDs)
Insulation resistance
Parameters of RCDs
Earthing resistance (4 measurement methods + ground resistivity measurement)
Continuity of protective and equipotential bondings
Phase sequence tester
Lighting measurement
Motor rotation direction tester
