The method of calibration of precision thermoelectric converters with the presence of thermocouples in the design is observed. The influence of the rate of change in the output thermo-EMF and the variability of the operation time intervals of the one AC/DC difference measuring cycle on the calibration method is investigated. A feature of the method is the availability of precision dc voltage comparators with a mechanical means of the internal measure regulation used for output signals observation among the measuring instruments. This situation leads to a variation of the time intervals from cycle to cycle. Also, the disparity of the required time arises from the need to regulate the input signal by the operator and to record the readings in the protocol.
