Description
The Model 2500A PAV replaces the very popular Model 2500. With the latest and most advanced DSP technology, this instrument provides a new level of performance and user friendliness. In addition, the 2500A PAV is considerably less expensive than other “traditional” PAVs. By keeping classic measurements, at- the-touch-of-a-button, the Model 2500A behaves more like an instrument and less a computer. The unit is extremely easy to use yet contains a host of features and performance characteristics that set it apart from all others.
Specifically targeted at Synchro/Resolver and LVDT/RVDT applications this instrument makes measurements of Phase Angle, In-Phase, Quadrature, Fundamental and Total a breeze. All parameters can be displayed simultaneously on a bright color high resolution graphical display. The Model 2500A even includes a built-in oscilloscope for viewing input waveforms.
Isolated inputs allow null, ratio and gain measurements of key parameters and a reference offset facilitates bridging measurements. A sensitive null meter is also included. An optional on-board reference generator has enough power to drive most LVDT/Synchro references. This feature can eliminate the need for an external reference; although the unit can be used with an external generator if so desired. The Model 2500A also includes pre-defined LVDT/RVDT functions such as (A-B)/(A+B) and (A-B)/Ref.
But the 2500A PAV goes further. By using an external shunt, it can also, measure power, power factor, THD, harmonics, and can be used to calculate impedance.
