LCR meter digital '' E7-8 ''.
Instruments for adjusting and controlling the PTA.The digital LCR meter `` E7-8 '' has been produced presumably since 1977. The LCR meter provides measurement of the parameters of capacitors, inductors. resistors, various elements of radio engineering circuits with digital readout of measured values and information output in the 8-4-2-1 code. The device can be used to determine the division ratio of transformers, check the quality of shielding, measure the capacitance of diodes and the contact resistance of switches. The LRC functions can be extended (measuring temperature, pressure, humidity, etc.) by using sensors that convert the measured physical quantity into capacitance, inductance, resistance or dielectric loss tangent. The measuring principle is based on a bridge method with phase-sensitive balancing detectors. The reading of the measured value is four-digit.
