Abstract
An electrical heater cable is positioned within an assembly of multiple junction thermocouple cables associated with the elongated gamma heated body of a local power measuring unit to electrically heat the body from an external source during a calibration period. The signal outputs of the thermocouples are measured during the calibration period for steady state analysis of the signal response to changes in heating rate produced either by additional electrical heating, by abrupt termination of electrical heating or by supply of sinusoidally varied heating current to the heater cable.
