Models 2003B and 2004 are high-accuracy AC voltmeters or true-RMS voltmeters. Exceptional noise rejection is provided by a conversion circuit with a crystal oscillator, which is set for either 50 or 50 Hz rejection. Both models are available for voltage or current input and allow special scaling for the output of a 5 A current transformer (CT). A screw-terminal barrier strip for power and signal is standard.

All AVG models use a precision op-amp rectifier circuit to provide an economical, high-resolution AC voltmeter, which is calibrated to display the true-RMS value of sinusoidal signals. All RMS models use an integrated circuit that computes the true-root-mean-square value of complex input signals. Screw terminals are provided for AC or DC coupling. AC coupling allows the measurement of the AC component or ripple from a signal with both AC and DC components. DC coupling allows the measurement of true-RMS, including AC and DC components, from DC to over 30 kHz. Maximum crest factor (Vp/Vrms) is 3:1).

BCD Output Standard
Non-isolated parallel BCD output is a standard feature and is implemented on the main circuit board. Additional data and control outputs can be provided by an optional upper board.

Options
The meter main assembly can be electrically configured for four voltage or five current input ranges. Upper-board options include four BCD output boards. Mechanical options include connectors and splash-proof lens cover which meets NEMA-4 standards.
