Abstract
The apparatus described is capable of measuring materials with loss tangents down to 3*10-3 although it is hoped in the future to improve this to 3*10-4. The apparatus is based on a Solartron frequency response analyser which is used to measure the voltage across and the current flowing through the sample. Complete computer control is available with on-line calculation of results enabling frequency sweeps to be performed in the minimum time. The results are available as printed data, punched tape or plotted on an XY recorder. Possible errors in the measurement are discussed.Keywords
