Description
The PROVA-2000/PROVA-2003 Clamp Meter is designed for high-accuracy measurement of AC and DC currents, voltages, resistance, and frequency in industrial, laboratory, and field environments. Its large 3 3/4-digit LCD with a fast 40-segment bargraph, sampling 30 times/sec, allows users to track transient events and waveform changes instantly. With a 55 mm jaw for cables and 65 mm for bus bars, the meter easily accommodates large conductors, making it perfect for power systems, industrial equipment, and electrical installations.
For versatile applications, the meter features DC/AC current up to 2500A/2100A, voltage up to 600V, analog output for oscilloscope or datalogger connection, and True RMS/average sensing depending on the model. Functions include auto-range for A, V, Hz, frequency measurement, resistance, continuity buzzer, diode testing, Max/Min capture, and Data Hold. The device also includes one-touch DC zero adjustment, auto-power-off, and 600V overload protection for safe operation. Its rotary switch simplifies function selection, making it a reliable tool for both professionals and technicians.
