The problem is warming up thermosensor when measuring resistance as a result of the allocation of Joule heat.
To control thermosensor (Fig. 1, a) proposed a contact device (Fig. 1b) with elastic gold contacts and measuring pulse duration was 100 ms (Fig. 1, B).
Created stand pulsed measurement provides a measurement of miniature thermosensor with 1% accuracy, which determines the error ADC oscilloscope. During the warm-up control thermosensor was not fixed within 0,1 ° C. Patented method of control.
