The PCE-830 Clamp Meter is used for measuring one to three phases of electrical quantities for alternating current (AC). This 3-Phase Clamp Meter also measures parameters such as voltage, current, frequency, harmonics, and power as well as indicating, according to standard EN50160, harmonic values, interharmonics, and asymmetrics. Interference, such as interruptions, leaks, overloads, or transience (from 16 µs) are detected with their corresponding values. The backlit LCD, with high resolution, can show up to 35 parameters simultaneously. Up to 3 clips can be attached at the same time to the Clamp Meter. In data logger mode, it can save up to 17,470 readings (3 phases / 4 conductors), in a simpler set up (1 phase / 2 conductors) it can save up to 52,400 readings, split into 85 groups. All this makes the PCE-830 Clamp Meter the ideal instrument for taking measurements over long durations. Measurement values obtained can be sent to a computer and be processed with the included analysis software. The device comes with everything needed to be measuring and analysing from the moment it arrives. Although the Clamp Meter comes calibrated from the manufacturer, an optional laboratory calibration and certificate, that meets ISO standards, can be ordered separately with the device or when a recalibration is required.
