JR/JR20-IMP DESCRIPTION The JR-IMP and JR20-IMP models are counters that can display two variables; the number of pulses of the actual process, and a total of accumulated pulses during several measures, both multiplied by a programmable factor. Accepts, by a DIP-switch selection, the most commonly used pulse generators, with a programmable factor range from 0,001 to 9,999; and an offset (initial counting value) programmable from 0 to 9999. Reset by keyboard or remote. The counting is always ascending unidirectional. Totalizer up to 999999 (informative only) visualized in to parts. Accepts the 2RE output option (works with the counting value not the total), with various programmable work modes.
