GFUVE is committed to providing our customers with leading innovative and technologically superior products, while maintaining metrology capability in power and energy measurement that is surpassed by none. Our engineers drew on the expertise and knowledge we acquired for our industry-leading legacy RM (Metronic) and RD (Dytronic) reference standards to develop the RX (Xytronic), the ultimate in power and energy measurement technology perfection.
Extended Measurement Range The GF333V2 is designed to operate over a broad Current, Voltage and Power Factor measurement range. A dynamic range of 30 VAC - 600 VAC and 5 mA – 200 A provides the versatility to operate in a multitude of power and energy applications. The AC direct current input provides fixed impedance (0.0005 Ohm) over the entire AC current input range. This capability is key to applications that require a fixed input burden and accurate yet fast measurement speed. The GF333V2 provides three-phase fully auto-ranging, simultaneous four-quadrant precision measurements, computes, records and presents instantaneous metrics. The GF333V2 allows the user to do more with a single instrument.

Internationalization The GF333V2 is designed for a global market where user languages may vary. The GF333V2 accommodates different languages as well as selectable VAR calculations and a broad range of energy measurement metrics including fundamental only Watts, VA and VAR. RX VAR calculation modes include Voltage 90 degree shifted, Integral VAR, Integral VAR 50 Hz, Integral VAR 60 Hz, RMS VAR, and Fundamental VAR.
