The Model 2600 Phase Angle Voltmeter replaces the very popular Model 2500A. With the latest and most advanced DSP technology, this instrument provides a new level of performance and user friendliness. In addition, the Model 2600 Phase Angle Voltmeter is considerably less expensive than other “traditional” Phase Angle Voltmeters. By keeping classic measurements, “at the touch of a button”, the Model 2600 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. In Vector mode, 4 out of 5 of these parameters can be displayed simultaneously. The Model 2600 Phase Angle Voltmeter 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 plenty of power to drive most LVDT/Synchro references. This feature eliminates the need for an external reference; although the unit can be used with an external generator if so desired. The Model 2600 also includes pre-defined LVDT/RVDT functions such as (A-B)/(A+B) and (A-B)/Ref. The optional third channel allows (A-B)/(A+B), in phase, QUAD and phase angle measurements to be made with respect to the oscillator input.

But the 2600 Phase Angle Voltmeter goes further. By using an external shunt, it can also, measure power, power factor, THD, harmonics, and impedance.
