Multifunction installation meter for IT isolated networks
The MPI-530-IT performs every installation verification measurement — fault loop, RCDs, insulation, earth and continuity — and is prepared for isolated IT systems, where it also tests residual current devices.
Advantages
Ready for IT networks
It tests general and selective RCDs from 10 to 1000 mA also in isolated IT systems, a capability that sets it apart from conventional multifunction meters.
Fault loop with 0.01 Ω resolution
It measures impedance with 23 A (44 A phase-to-phase) in the 95…440 V range and, with a 15 mA current, evaluates RCD-protected circuits without tripping the breaker.
Insulation up to 10 GΩ
Test voltages from 50 to 1000 V with automatic discharge, measurement through the UNI-Schuko plug and automatic testing of 3-, 4- and 5-core cables with the AutoISO-1000C adapter.
Earth, continuity and light intensity
Four earth measurement methods, soil resistivity by Wenner, bidirectional continuity with ±200 mA, quick PE check by touch electrode and light measurement with an external probe.
Recording and communication
It records voltage, current, powers, harmonics up to the 40th and THD; results are stored in a tree memory and downloaded over USB or Bluetooth.
Applications
- Verification of installations with IT earthing systems: hospitals, mining and industry.
- Electric shock protection measurements to IEC 61557 in LV installations.
- Testing of RCDs, PE continuity and earth resistance with four methods.
- Basic mains diagnostics with harmonics, THD and phase sequence.
About the product
The MPI-530-IT shares the robust IP54 housing and the CAT IV 300 V category of the AMPI-530 family and is powered by LR14 cells or a NiMH battery with built-in charger; its distinctive feature is the ability to measure in isolated IT networks, completing loop, RCD, insulation, earth, continuity and light measurements with USB and Bluetooth communication.

Frequently asked questions
What makes the MPI-530-IT different?
It is prepared for isolated IT networks, where it tests general and selective RCDs from 10 to 1000 mA in addition to all standard installation measurements.
Where are IT systems used?
In installations where supply continuity is critical, such as hospital operating theatres, mines and certain industrial plants; the meter covers their verification.
Which insulation voltages are available?
Test voltages of 50, 100, 250, 500 and 1000 V with measurements up to 10 GΩ and automatic discharge after the test.
Does it measure earth resistance?
Yes, with the 3-pole, 4-pole, 3-pole plus clamp and two-clamp methods, plus soil resistivity using the Wenner method.
How are results transferred?
Over USB 2.0 or Bluetooth from a tree memory with 6000 cells and 10 000 records, ready for report generation.
