Phase Angle Voltmeter

Model Instrument 2251

The Model 2251 Phase Angle Voltmeter from North Atlantic Industries is one of the most versatile AC Measurement Instruments available. It employs a microprocessor-based design, utilizing Fast-Fourier Transform techniques that combine many of the capabilities of today's network/waveform analyzers in a Digital Analyzing Voltmeter configuration. Similar to Model 2250, the 2251 incorporates the most commonly used functions, providing a more cost-effective measurement instrument with fewer features and reduced accuracy requirements. This Phase Angle Voltmeter is specifically designed for the Synchro/Resolver and LVDT/RVDT marketplace. One touch allows the 2251 to make highly accurate ratio measurements in both phase-sensitive and voltage modes; measures percent, Total Harmonic Distortion and the magnitude and phase of selected harmonic, and computes the percent deviation of a signal from a selected nominal. Isolated inputs allow null, ratio and gain measurements of key parameters.

Features
The 2250 Phase Angle Voltmeter is exceptionally “user friendly”. Unlike menu-driven Instruments, by simply pressing individual switches on the front panel, you can access a wide number of functions, including:

Total, Fundamental, In-phase and Quadrature voltage and Phase Angle measurements
Reference phase offset from the Signal by up to 360 °
Highly accurate Ratio measurements in both phase-sensitive & voltage modes
Individual Voltage Ranges & Full Autorange
Local & Remote IEEE, GPIB Programming

The instrument calibrates itself. At turn-on or frequency change, the instrument automatically initiates a self-calibration sequence. This checks critical performance criteria and makes internal adjustments that maximize accuracy. This sequence can be initiated by the user at any time. Long term accuracy and stability is thus assured.
