High-frequency inductance and capacitance meter '' E12-1A '' (E7-5A).

Instruments for adjusting and controlling the PTA.The high-frequency inductance and capacitance meter "E12-1A" has been produced by the Gorky Frunze Plant since the 1st quarter of 1965. From the second half of 1970 the device was referred to as "E7-5A". Both devices are the same. The device "E12-1A" is designed to measure small values ​​of inductances and capacities (capacitors should be with low losses: air, mica, ceramic, etc.). Technical characteristics of the device: Limits of measurement of inductances: from 0.05 μH to 100 μH (5 subranges). The measurement is performed at the following frequencies: I sub-band: 1.55 ... 1.1 MHz. II sub-band: 505 ... 355 kHz. III sub-band: 155 ... 110 kHz. IV sub-band: 50.5 ... 35.5 kHz. V sub-band: 15.5 ... 11.0 kHz. Capacitance measurement limits: from 1 to 5000 pF. The measurement is performed at frequencies of 300 ... 700 kHz. Power supply: 220 V. Power consumption: 20 W. Dimensions of the device: 390x280x290 mm. Weight: 15 kg.
