一、因多功能校验仪自身的温度补偿数据不准,导致检定数据有误在检定配热电偶信号的温度二次仪表时,使用者通常使用多功能校验仪的内置式温度补偿功能进行检定,而内置式温度补偿功能是否准确,根据笔者多年的检定经验,这一点很多使用者根本不关心,从未对其补偿功能进行检定。在使用热电偶时,如果补偿端的温度不合适,会给测量数据带来较大误差。所以在实际工作中,使用者必须对使用的多功能校验仪进 First, due to multi-function calibrator’s own temperature compensation data are not allowed, resulting in verification data is incorrect In the test with thermocouple temperature secondary instrument, the user usually use the multi-function calibrator built-in temperature compensation function Verification, and built-in temperature compensation function is accurate, according to the author’s many years of verification experience, many users do not care about this point, it has never checked the compensation function. When using the thermocouple, if the temperature of the compensation end is not suitable, the measurement data will bring greater error. Therefore, in practical work, the user must use the multi-function calibrator into
