Abstract:
An automated measuring system developed by authors for studying the temperature dependence of dielectric spectra of ferroelectrics in the frequency range 12Hz-100kHz, the temperature range 80-450K and the amplitude of the measuring signal 5mV -1.275v has been presented. It is based on the GW Instek LCR-819 LCR Meter, the Measurement Computing USB-TEMP-AI temperature meter and an OWON ODP3033 programmable power supply. The temperature measurement resolution is 0.001K and the controlled rate of temperature change is from 0.001K/min to 1K/min. The control software, created in the LabViewgraphical environment, makes it possible to carry out measurements in an automatic mode, present the results obtained in the form of graphs (Cole-Cole plot and frequency dependency of ? and ??) and save the data as a file.
