Function
Used to measure AC leakage current, earth leakage, and load current in electrical installations, helping diagnose insulation deterioration, unwanted leakage paths, or load imbalance. Suitable for maintenance tasks, inverter-based equipment, and general electrical troubleshooting.
Usage: select the appropriate range, clamp the jaw around the target conductor(s) according to measurement type, and read the value on the display. Filtering mode (50/60 Hz) may be activated to suppress high-frequency noise.
Specific use:
detection of leakage currents causing nuisance tripping
comparison between WIDE and 50/60 Hz modes to isolate harmonic or inverter-induced leakage
measurement in tight spaces requiring small-jaw access
Limitations: AC only; not suitable for voltages above CAT III 300 V; accuracy impacted near strong magnetic fields; conductor must fit fully within the jaws for correct measurement.
Use precautions:
inspect the jaws for damage or debris before use
keep fingers behind the barrier during measurement
avoid measuring near strong magnetic fields when possible
ensure jaws fully close around the conductor
set to OFF after use to preserve battery life
