Phase Angle Voltmeter, High Accuracy

Model Instrument 2250

The Model 2250 Phase Angle Voltmeter is the most accurate and versatile AC measurement tool available. This instrument 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. Designed for the Synchro/Resolver and LVDT/RVDT marketplace, this Phase Angle Voltmeter accurately makes measurements of Phase Angle, In-Phase, Quadrature, Fundamental and Total, as well as impedance, power and harmonics. Isolated inputs allow null, ratio and gain measurements of key parameters. A reference phase offset facilitates bridging measurements. A sensitive null meter is included for precise nulling.

Features
The instrument is exceptionally “user friendly”. Unlike menu driven Instruments, by simply pressing individual switches on the front panel, you can access a wide number of single touch functions, such as:

Total, Fundamental, In-phase and Quadrature voltage and Phase Angle measurements
Reference phase offset from the Signal by up to 360º
Highly accurate Ratio measurements in both phase-sensitive and voltage modes
Measurement of Total Harmonic Distortion and magnitude and phase of a selected harmonic
Computation of the percent deviation of a signal from a selected Nominal value
Display of magnitude in db relative to either the Reference input or a selected value
Reference Frequency & Amplitude Measurement
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.
