INTRODUCTION

Automatic anti-interference precision medium loss measuring instrument is used for field anti-interference dielectric loss measurement, or laboratory precision dielectric loss measurement. The instrument is integrated structure, built-in dielectric loss bridge, frequency conversion power supply, test transformer and standard capacitor. Frequency conversion anti-interference and Fourier transform digital filtering technology are used to measure automatically and intelligently. The measured data are very stable under strong interference. The measurement results are displayed by large screen liquid crystal and can be printed out with a micro printer.
