Product Description

In 1955, North Atlantic Industries created the first Phase Angle Voltmeter.
It was an event of considerable importance in the electronics industry. Now from North Atlantic comes an equally significant advance. The Model 2250 – the most versatile AC measurement tool yet developed. The 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 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 and a reference phase offset facilitates bridging measurements. A sensitive null meter is included for precise nulling. The instrument is unusually “user friendly”.
Unlike menu driven Instruments, simply by pressing individual switches on the front panel, you can access a wide number of functions. Functions accessed by a single touch include:

  • 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.
