Abstract :
A formula for determining the time-constants of thermoelectric effects in thermal converters from the FRDC-dc transfer difference measurements in relation to the reversing frequency is derived. The error due to higher-frequency harmonics in the FRDC-waveform is calculated for shunt capacitances and dielectric losses in the heater/range-resistor combination
