4.2. Key Measurement Functions

The MI 3152 EurotestXC offers a comprehensive suite of measurement capabilities:

• Insulation Resistance: Measures with DC voltage from 50 V to 1000 V.
• Varistor Test: Checks varistor functionality.
• Continuity of PE Conductors: Performed with 200 mA DC test current (with polarity change) or 7 mA test current (without RCD tripping).
• Line/Loop Impedance: Includes combined Z AUTO and Loop impedance with Trip Lock RCD function.
• TRMS Voltage and Frequency: True RMS measurements for voltage and frequency.
• Phase Sequence: Determines the correct phase rotation.
• Power and THD Measurement: Measures power and Total Harmonic Distortion (up to the 12th harmonic).
• RCD Testing: Supports general and selective RCDs (Type AC, A, F, B, B+, MI RCD, EV RCD, PRCD, PRCD-K, PRCD-S).
• Earth Resistance: Utilizes 3-wire and 2-clamps methods. Specific earth resistance can be measured with an optional Ro-adapter.
• TRMS Leakage and Load Currents: Requires optional accessories.
• First Fault Leakage Current (ISFL): Detects initial leakage currents.
• Insulation Monitoring Devices (IMDs) Testing: For monitoring insulation systems.
• Illumination: Requires optional accessories.
• High Resolution Loop Impedance (mΩ): Requires optional accessories.
• EVSE AUTO SEQUENCES and Function Inspections: For electric vehicle supply equipment testing.
• Cable Location: Requires optional accessories for determining cable locations.

4.3. Automated Test Procedures

The instrument includes predefined automatic test sequences for efficiency:

• Auto TT: (U, Zln, Zs, Uc)
• Auto TN/RCD: (U, Zln, Zs, Rpe)
• Auto TN: (U, Zln, Zlpe, Rpe)
• Auto IT: (U, Zln, Isc, Isfl, IMD)

Automated RCD and Impedance testing procedures streamline common tasks.

5. Maintenance and Care

To ensure the longevity and accuracy of your MI 3152 EurotestXC, follow these maintenance guidelines:
