Description
The E0206 is a universal counter, made by IEMI in Bucharest and designed at the ICE research institute [1].
ICE’s laboratory for electronic instruments for measuring electrical quantities designed all the institute’s generations of oscilloscopes, voltmeters, multimeters, signal generators, frequency meters, logic analysers, RLC bridges and stabilised AC power supplies; they went into production at IEMI or in ICE’s own microproduction workshop, and equipped industrial laboratories and production lines as well as teaching and research laboratories [1]. In the 1970s and 1980s about half of the components of measuring instruments were imported; after 1980 about three quarters were Romanian [1].
It has a seven-digit LED display [2]. IEMI’s production table lists 1,159 units made in 1981–1985 [2].
Its list price, set in 1982, was 38,000 lei [3].
Annex III.2.7 says it measured frequency from 10 Hz to 50 MHz, period, multiple periods, time intervals and the ratio of two frequencies, and totalised pulses; its second input covered 1 Hz – 10 MHz [4].
