Three-Phase Clamp Meter with network analyzer / power and energy meter (real time) with data logger, graphic display, interface for PC and software The Three-Phase Clamp Meter (Graphic Power Quality Analyzer) PCE-GPA 62 is used for single-phase or three-phase measurements of the active, reactive and apparent power, power factor, phase angle, energy, voltage, current as well as peaks and harmonics up to 50º of the harmonic waveform. The Three-Phase Clamp Meter PCE-GPA 62 comes with a built-in graphic display to show network analyzer values. Measured values can be both recorded and transferred to a PC for further analysis. The Three-Phase Clamp Meter PCE-GPA 62 is a professional handheld device to determine several parameters. Thanks to the backlight display, it is possible to get an accurate reading of measured values even with poor light conditions. Although the Three-Phase Clamp Meter PCE-GPA 62 comes calibrated from the manufacturer, an optional laboratory calibration and certificate, that meets ISO standards, can be ordered separately with the device or when an annual recalibration is required.
