Multifunction installation meter with power quality recorder
The AMPI-540 combines every installation verification measurement with a three-phase class S power quality recorder to EN 61000-4-30, operated from a 7-inch touchscreen.
Advantages
One instrument instead of several
It measures fault loop impedance also in RCD circuits without tripping, RCD parameters, insulation, earth by four methods with soil resistivity, continuity, light intensity, phase sequence and motor rotation direction.
Three-phase class S recorder
It logs voltages up to 500 V, currents up to 3 kA, frequency from 40 to 70 Hz, powers, power factor, harmonics up to the 40th and THD in accordance with class S of EN 61000-4-30.
A 7-inch touchscreen
The 800 × 480 pixel TFT touch panel shows built-in help diagrams, an oscilloscope view, a phasor diagram and results that remain legible in any conditions.
Automated measurements
Autotest sequences, the automatic RCD test mode and the AutoISO-1000C adapter shorten measuring time; a voice note or a photograph can be attached to each result.
Expandable memory and full connectivity
The removable microSD card extends the memory easily, and data is transferred over USB, Bluetooth or Wi-Fi for reporting and record analysis.
Applications
- Verification of domestic and industrial electrical installations to current regulations.
- Power quality logging and basic diagnostics of three-phase networks.
- Detection of potential savings with the energy loss calculator.
- Documented electric shock protection measurements with reports.
About the product
The AMPI-540 sits in an IP51 housing of 288 × 223 × 75 mm with CAT IV 300 V measuring category and an 11.1 V 3.4 Ah Li-Ion battery; the 7-inch touchscreen, the microSD card and the USB, Bluetooth and Wi-Fi interfaces make it a complete platform for verifying installations and recording power quality.

Frequently asked questions
What does the AMPI-540 add over a classic installation meter?
A three-phase class S power quality recorder to EN 61000-4-30, a 7-inch touchscreen, a removable microSD memory card and Wi-Fi communication, on top of all standard verification measurements.
Which power quality parameters does it record?
Voltages, currents, frequency, active, reactive and apparent power, power factor, cosφ, harmonics up to the 40th and THD for voltage and current.
Can measurements be automated?
Yes. Factory autotest sequences can be extended with user sequences, the RCD test has an automatic mode and the AutoISO-1000C adapter tests multi-core cables automatically.
How is data documented?
A voice note or photograph can be attached to each measurement, and results move quickly from meter to report over USB, Bluetooth, Wi-Fi or the microSD card.
What battery does it use?
A rechargeable 11.1 V 3.4 Ah Li-Ion battery that extends the operating time of the meter.
