Description
The E0406 is a high-frequency millivoltmeter, 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].
Its band reaches 250 MHz; it appears in IEMI’s 1988 range [2].
Annex III.2.8 calls it a laboratory instrument measuring AC voltages of 0.01–10 V between 0.1 and 250 MHz, for adjustments, repairs and measurements [3].
