The Rogowski coil has a length of 45.7cm (18 inches), conquerinq difficult-to-measure wires
Even in a crowded and deep cabinet, the flexible jaws can be easily wrapped around the wires surrounded by obstacles, completing tasks that are difficult for traditional clamp meters
Inrush current The freguncy measurement function can filter out the noise and accurately capture the instantanenous current when the motor starts; the current frequency is displayed on the same screen during the voltage measurement.
60MΩ resistance measurement Automatic/manual range switch at any time
With frequency measurement function, the current frequency can be displayed on the same screen during voltage measurement, and the mutual change of voltage and frequency can be quickly viewed
CE certification, ETL certification and ROHS testing, the use of products is safe and environmentally friendly, safe and reliable.
