The report describes a device for continuous recording of the weight of a human subject. The frame on which the subject may either sit or lie is carried by three load cells mounted as a tripod. The electrical signals from the strain-gauges permit detection of a weight change of one gram. Insulation and heating of the load cells to a constant temperature 0.1C permit use of the system in the presence of rapid changes in environmental temperatures. Circuits are described for automatic regulation of load cell temperature.
