Each measurement run takes approximately 4 hours

Abstract

This is the report on new development of an automated precision load-based measurement setup for thermoelectric power of different types of samples in the temperature range 5 - 330 K. The problems in the old spring-based setup have been solved by making load-based setup. This new setup takes nearly 4 h for each run and typical error is within 5 %. A high quality calibration been demonstrated using high purity platinum wires.
