    • An apparatus for correcting the error due to the non-linear variation in an output signal produced by an electrical system for measuring a physical quantity, e.g. temperature, by means of a probe, the electrical resistance of which is sensitive to the variation of the physical quantity, in which the maximum value of the error in the output signal to be corrected in the range of measurement considered is first determined. Then a correcting signal is applied as a compensating signal to one of the probe outputs, which signal is in the same ratio to said maximum error as the instantaneous output signal is to the value of the output signal which produces said maximum error. Conveniently the correcting signal is applied as a feedback signal from an output terminal of the system.
    • 一种用于校正由用于测量物理量的电气系统产生的输出信号中的非线性变化引起的误差的装置,例如, 温度,其电阻对物理量的变化敏感,其中首先确定在所考虑的测量范围内待校正的输出信号中的误差的最大值。 然后将校正信号作为补偿信号施加到探头输出中的一个,该信号与所述最大误差的比率相同,因为瞬时输出信号是产生所述最大误差的输出信号的值。 方便地,校正信号作为来自系统输出端的反馈信号。
