• The largest touch screen on the market (7”) – remarkable ergonomics and ease of use.
• Removable microSD memory card – easy increase of memory capacity.
• Quick measurement of the fault loop impedance in networks secured with RCD without triggering (up to several seconds).
The MPI-540 can record 50/60 Hz power quality parameters in accordance to S class of EN 61000-4-30:
  • voltage L1, L2, L3, – average values in the range up to 500 V, 
  • L1, L2, L3 currents, – average values, current measurement in the range up to 3 kA (depending on the current probes used),
  • frequency in the range of 40 Hz – 70 Hz,
  • active (P), reactive (Q) and apparent (S) power,
  • power factor (PF), cosφ, tanφ,
  • harmonics (up to 40th for voltage and current),
  • total harmonic distortion (THD) for current and voltage,
  • recording of events for current and voltage,
  • energy flow – 4 quadrants.
