The Model 2500A Phase Angle Voltmeter replaces the very popular
Model 2500 PAV. With the latest and most advanced DSP technology, this instrument provides
a new level of performance and user friendliness. In addition, the 2500A Phase Angle
Voltmeter 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 like 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 high resolution color 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 Phase Angle
Voltmeter goes further. By using an external shunt, it can also, measure power, power
factor, THD, harmonics, and impedance.
