Description
The N2603 is an electronic tachometer, made by IEMI in Bucharest [1]. IEMI’s production table lists 630 units made in 1981–1985 [1].
Its list price, set in 1982, was 20,000 lei [2].
Annex III.2.11 describes a digital tachometer for 6 – 100,000 rpm, showing the speed in rpm or in cycles per second whatever the number of pulses per revolution and the transducer used. It could also show the speed multiplied by a preset number (when the transducer could not be fitted directly on the measured gear), the percentage ratio of two speeds, the slip, or other quantities from transducers with a frequency output, such as flow or linear speed, and could signal preset speeds. It had a four-digit display with memory, automatic range and decimal-point switching, a BCD output for a printer and a stabilised +15 V output for supplying transducers; photoelectric or induction pulse transducers were supplied as accessories [3].
