Digital multifunction meter in an ergonomic housing addressed to both installers and advanced measurement engineers. It enables all measurements provided for in PN-EN 61557:

• Short-circuit loop impedance,
• parameters of RCD circuit breakers,
• insulation resistance,
• ground resistance,
• continuity of protective and compensatory connections.

The meter is the only multifunctional device on the market that allows measurements of insulation resistance with voltage up to 2500 V and automatic measurement of insulation resistance of 3-, 4- or 5-wire wires or cables using the AutoISO-2500 adapter. The product allows for accurate measurement of short-circuit loop impedance (resolution 0,01Ω) in L-PE circuits in networks with RCD circuit breakers. It has the function of measuring the actual actuation time and the operating current of the RCD circuit breaker with a single actuation of the circuit breaker.

Measurements of short-circuit loop impedance:

• measurement of impedance with current of 23 A (44 A at interphase voltage) - short-circuit resistor Rzw=10 Ω,
• measuring voltage range: 95...440 V, frequency 45...65 Hz,
• short-circuit loop impedance measurement with a resolution of up to 0,01 Ω, in installations protected by RCD circuit breakers with IΔn≥30 mA without their operation,
• automatic calculation of short-circuit current; distinguishing between phase and interphase voltage,
• measurements using UNI-Schuko plug with a button triggering the measurement (also with switched L and N wires) or wires with a length of 1,2 m, 5 m, 10 m, 20 m, with the possible use of 3-phase socket adapters. (AGT).

Testing of residual current circuit breakers type AC, A and B:

• measurement of ordinary, short-circuit and selective circuit breakers with rated differential currents of 10, 30, 100, 300, 500 and 1000 mA,
• function of automatic measurement of the full set of circuit breaker parameters (after pressing the “START” button once, the meter performs the entire set cycle of measurements including the possibility of measuring the impedance of the short circuit loop L-PE with a current of 15 mA),
• the shape of the forced leakage current chosen by the user: sinusoidal (start from the slope rising or falling), unidirectional pulsating (positive or negative), unidirectional pulsating with direct current primer (positive and negative), constant (positive and negative),
• measurement of trigger current IA with increasing current,
• measurement of tA operating time at ½IΔn, 1IΔn, 2IΔn and 5IΔn currents,
• measurement of UB touch voltage and RE protection cable resistance without triggering the circuit breaker,
• detection of conversion of L and N wires in the socket; does not affect the performance of measurements,
• the ability to measure the current of IA operation and the actual time of tAI operation with one RCD shutdown,
• measurements for voltage 95...270 V.

Isolation resistance measurements:

• Measuring voltages: 50 V, 100 V, 250 V, 500 V and 1000 V and2500 V
• measurement of insulation resistance up to 10 GΩ,
• setting 3 time intervals T1, T2, T3 from the range of 6-600 s,
• calculation of 2 absorption coefficients,
• protection of the meter against the presence of voltage on the object and the appearance of voltage during measurement,
• automatic discharge of the capacity of the measured object after the measurement is completed,

Low voltage measurement of resistance of protective and compensatory connections:

• measurement of continuity of the protective conductor with current ≥200 mA in two directions,
• measurement of small current with acoustic and light signalling (green diode),
• self-calibration of measuring wires - the possibility of using wires of any length.

Measurements of ground resistance:

• 3-wire technical method measurement with 2 auxiliary electrodes,
• internal voltage source with a frequency suitable for 50/60 Hz network.

Product Features:

• Quick validation of PE protective cable connection using touch electrode.
• Checking the order of phases.
• High voltage indication on the meter connectors (yellow diode).
• Memory of 990 records (57500 individual results), data transmission to the computer via USB or radio connection.
• Real-time clock (RTC) - measurement time written to memory
• Power from a battery or battery.
• The device meets the requirements of PN-EN 61557.
• Short-circuit loop impedance measurement ZL-PE, ZL-N, ZL-L
• Current measurement 23/40 A - measuring range according to PN-EN 61557: 0,13...1999,9 Ω
• (for measuring cable 1,2 m):
