Model 2003B
is a 4 1/2 DC voltmeter which provides high-resolution and high-accuracy at very reasonable cost. Display span is ±19,999 counts. Accuracy 99.98% of reading. The 2003B also provides exceptional stability and noise rejection. Its conversion circuit uses a crystal oscillator, which is tuned for either 50 or 60 Hz rejection.

BCD OUTPUT STANDARD
Unbuffered, non-isolated parallel BCD output is a standard feature of the 2003B and is implemented on the main circuit board. It is good for about 1 ft and can be used to interface the 2003B to a comparator (Model 872A) or a printer (Model 820A). Additional data and control outputs can be provided by an optional upper board.

OPTIONS
The meter main assembly can be electrically configured for four input ranges, high-impedance 3-wire ratio input, high read-rate, and ultra-low span tempco. Upper-board options include four BCD output boards and a single-setpoint controller.

Mechanical options for the standard 1/8 DIN case include a screw-terminal barrier strip for signal and power, and a splash-proof lens cover which meets NEMA-4 requirements. A NEMA-size case is optional. For additional information, please refer to the Options and Mechanical sections.
