The Arbiter Systems, Inc. Model 911A Phase Angle Meter is a compact, hand-held unit capable of voltage to current phase angle measurements with 1 degree accuracy
The Arbiter Systems®, Inc. Model 911A Phase Angle Meter is a compact, hand-held unit capable of voltage to current phase angle measurements with 1 degree accuracy. Optional adapters allow voltage to voltage phase angle measurements, and extended current input ranges, with the same accuracy.
The clamp-on current transformer (CT) eliminates the need to break the current circuit, making measurements possible where interruption of power cannot be tolerated. The wide range of both the current and voltage inputs makes scaling or tap selection unnecessary. A LCD display provides outstanding readability in medium to high ambient light, along with low current drain for long battery life.
The Model 911A standard display is ±180 degrees. For applications which require 0 to 360 degree display, or the ability to measure voltage, current, and/or frequency, use the Model 918B Phase Angle Multimeter. The Model 918B measures voltage, current, and many other useful quantities. Like the Model 911A, the Model 918B uses a clamp-on CT and has a variety of accessories for other input ranges.
For applications requiring simultaneous measurements in three-phase systems, or the ability to measure harmonic-rich waveforms, including measurement of harmonics and K-factor, consider the Model 931A Power System Analyzer, the Model 930A Three Phase Power Analyzer, or the Model 929A Three Phase Power Meter. All three models offer outstanding accuracy (0.05% and 0.05°), and the Model 931A includes a built-in timer, plus a DMM for calibrating transducers.
