Carrying out the verification measurements described in HD 60364-6 for a low-voltage installation (fault loop, RCDs, insulation, earth and continuity) with IEC 61557 methods is best done with a multifunction tester that also records basic mains parameters. The AMPI-530 measures the loop from 0.130 to 1999.9 Ω per IEC 61557-3 with 0.001 Ω resolution and ±(5 % m.v. + 0.03 Ω) up to 19.999 Ω, tests AC, A and B RCDs from 10 to 1000 mA per IEC 61557-6, measures insulation from 50 to 1000 V up to 9.99 GΩ, earth with clamps and soil resistivity, and records voltage, current, power and harmonics up to the 40th.

Advantages
Complete diagnostics to IEC 61557
It measures Z L-PE, Z L-N and Z L-L fault loop impedance with 23 A (44 A phase-to-phase), also in RCD-protected circuits without tripping, and calculates the prospective short-circuit current automatically.
RCD testing from 10 to 1000 mA
It checks general and selective breakers of AC, A and B types, measuring the tripping time tA and the tripping current IA, starting from the positive or the negative half of the waveform.
Insulation up to 10 GΩ and continuity
Test voltages of 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; PE continuity is verified with ±200 mA in both directions.
Earth by four methods plus a light meter
Earth resistance is measured with the 3-pole, 4-pole, 3-pole plus clamp and two-clamp methods, soil resistivity with the Wenner method, and an external probe measures light intensity.
Single-phase mains recorder
It records voltage up to 500 V, current up to 3 kA with clamps, frequency, powers, cosφ, harmonics up to the 40th and THD, with a tree memory of 6000 cells and 10 000 records and USB and Bluetooth transfer.
Applications
- Verification of domestic and industrial electrical installations to IEC 61557.
- Electric shock protection measurements for commissioning and maintenance.
- Testing of RCDs, continuity of PE conductors and earth resistance.
- Basic mains diagnostics: harmonics, THD, powers and phase sequence.

Frequently asked questions
Which multifunction tester covers the HD 60364-6 verification tests and also records harmonics?
The AMPI-530 combines IEC 61557 measurements (loop from 0.130 to 1999.9 Ω, AC, A and B RCDs from 10 to 1000 mA, insulation up to 9.99 GΩ, earth and 200 mA continuity) with a single-phase recorder for voltage up to 500 V, current up to 3 kA, power and harmonics up to the 40th, with 16 h of recording on battery.
What resolution does the AMPI-530 offer for fault loop measurement?
0.001 Ω from 0 to 19.999 Ω, with ±(5 % m.v. + 0.03 Ω); from 20.00 to 199.99 Ω it resolves 0.01 Ω with ±(5 % m.v. + 0.3 Ω), and the prospective short-circuit current is calculated up to 40 kA.
What does the AMPI-530 measure?
Fault loop impedance, RCD parameters, insulation resistance up to 10 GΩ, earth resistance and soil resistivity, continuity with ±200 mA, light intensity, phase sequence and single-phase mains parameters.
Can it measure the loop without tripping the RCD?
Yes. A 15 mA measuring function avoids tripping residual current devices with a rated current of 30 mA or higher.
Which RCDs can it test?
General and selective breakers of AC, A and B types with rated currents of 10, 30, 100, 300, 500 and 1000 mA, measuring both tripping time and tripping current.
How are the results downloaded?
The tree memory stores 6000 cells and 10 000 records, transferred over USB 2.0 or Bluetooth to prepare test reports on a computer.
How is the meter powered?
With four LR14 alkaline cells or a 4.8 V 4.2 Ah NiMH battery; the charger is built in and works from the mains or from a 12 V car socket.
