E7-28 Broadband Immittance Analyzer is a precision instrument of accuracy class 0.1 with a wide range of operating frequencies. By technical parameters, it replaces most of the E7 class devices manufactured in the CIS countries.

E7-28 broadband immittance analyzers are designed to measure the immitance parameters of electrical radio elements (ERE) in the frequency range from 25 Hz to 10 MHz.

Scope - scientific research, control of electrical parameters of electric energy devices at enterprises, in repair shops, scientific institutions.

The device measures the following immitance parameters:

Lp, Ls - inductance in a parallel, serial equivalent circuit;

Cp, Cs - capacity in a parallel, sequential equivalent circuit;

Rp, Rs - active resistance in a parallel, serial equivalent circuit;

X is the reactance in a series equivalent circuit;

G is the active conductivity in a parallel equivalent circuit;

B - reactive conductivity in a parallel equivalent circuit;

tg δ is the loss tangent (the designation D is allowed - loss factor);

Q - quality factor;

| Z | - integrated resistance module;

| Y | - module of complex conductivity;

φ is the angle of the phase shift of the complex resistance.

Objects of measurement: capacitors, inductors, transformers, resistors, relays, switches, diodes, cables, input resistances and capacities of oscilloscopes, voltmeters and other devices. With appropriate sensors, the device can measure various physical quantities.

The measuring ranges correspond to the values ​​indicated in the table.
