ILX Lightwave 204B Overview

In its base configuration, Model 204B is a high-accuracy ±3,999-count DC voltmeter which fills the gap between 3 1/2 and 4 1/2 digit resolution. The most sensitive standard input range is ±39.99 mV full-scale and provides 10 µV resolution. Extended-range options are available to ±4,999 and ±5,999 counts. Accuracy is 99.95% of reading.

Unbuffered, non-isolated parallel BCD output is a standard feature of the 204B and is implemented on the main circuit board. It is good for about 1 feet and can be used to interface the 204B to a comparator (Model 872A) or a printer (Model 820A). Additional data and control outputs can be provided by an optional upper board.
