Description
Inductive current measurement allows testing without opening the circuit—simply clamp around the conductor—making it ideal for electrical maintenance and diagnostics in photovoltaic (PV) systems, where comparing string currents helps detect faults quickly.
The inrush current (startup current) measurement supports peak analysis when motors start (HVAC, pumps, high-power lighting), helping you size cables, protections and fuses correctly. The VFD mode provides more reliable measurements on frequency converters from 45 Hz to 1 kHz.
With integrated Bluetooth 4.0 and the free Meterbox Pro app (Android/iOS), you can monitor readings live, log data and analyse results later. Internal memory stores 100,000 readings (16 groups) with date and time.
