Key Features & Benefits

🔍 High-Sensitivity Leakage Detection

• Measures AC leakage current from 0.1mA to 60A (industry-leading 1mA resolution)

• True RMS for accurate readings on distorted waveforms (VFDs, inverters, etc.)

🛠️ Professional-Grade Design

• 40mm oversized jaw – Fits thick conductors (ideal for parallel cables & busbars)

• CAT IV 600V/CAT III 1000V safety rating – For use in hazardous environments

• IP54 rated – Resists dust and water splashes

📊 Advanced Functionality

• Data Hold & Relative Mode – Isolate leakage values from background noise

• Min/Max/Avg recording – Track intermittent faults

• Backlit LCD – Clear readings in dark substations or panels

⚡ Multi-Function Capability

• Measures AC voltage (0.1V-600V), resistance (0.1Ω-60MΩ), frequency (10Hz-1kHz)

• Continuity buzzer & diode test – For comprehensive circuit checks
