Anti-interference Dielectric Loss Tester
Performance Characteristics
The automatic anti-interference precision dielectric loss tester is used for on-site anti-interference dielectric loss measurement, or for precise dielectric loss measurement in the laboratory. The instrument is an integrated structure, with built-in dielectric loss bridge, variable frequency power supply, test transformer, and standard capacitor, etc. It adopts variable frequency anti-interference and Fourier transform digital filtering technology, fully automatic intelligent measurement, and the measurement data is very stable under strong interference. The measurement results are displayed on a large screen LCD, and a built-in micro printer can print out the results.
