the differencebetweenthetrueorbestacceptedvalueofsome quantityand themeasuredvalue.誤差是真實量或者最抱負量與測量值的差。Precisionisameasureoftherepeatabilityofaseriesofdatapointstakeninthemeasurementofsomequantity.精度是指在一些量的測量中實行對一些數(shù)據(jù)點的重復測量。Recallthatresolutionwasdefinedintheprevioussectionastheminimumdiscerniblechangeinthemeasurandthatcanbedetected.區(qū)分率在前面局部被定義為在測量中檢測到的最小可區(qū)分的變化。Thesecouldbecausedbyinaccuratecalibration,mismatchedimpedances,response-timeerror,nonlinearities,equipmentmalfunction,environmentalchange,andloadingeffects.系統(tǒng)誤差是由于不準確的校準，不匹配的阻抗，反響時間誤差，非線性，設備故障，環(huán)境轉變和載荷效應所引起的。Thebestwaytodetectthepresenceofasystematicerroristorepeatthemeasurementwithacompletelydifferenttechniqueusingdifferentinstruments.檢測系統(tǒng)誤差的最好方法是用不同的儀器和完全不同的方法重復測量。Randomerrors(alsocalledaccidentalerrors)tendtovaryinbothdirectionsfromthetruevaluebychance.隨機誤差〔也稱偶然誤差〕往往是在真值的各幅度范圍內(nèi)隨機變化獲得。Theseerrorsareunpredictableandoccurbecauseofanumberoffactorsthatdeterminetheoutcomeofameasurement.這些誤差的發(fā)生是不行預知的，偶然的，由于由很多因素打算了一個測量的結果。Randomerrorsaregenerallysmallandmaybecausedbyelectricalnoise、interference、vibrationgainvariationofamplifiers,leakagecurrents,drift,observationalerror,orotherenvironmentalfactors.隨機誤差一般較小并且可能是由電噪聲、干擾、放大性增益變化、泄漏電流、漂移、觀測誤差或者其他環(huán)境因素造成。

techniquestodeterminetheuncertaintyofthefinalresult.削減隨機誤差最好的方法就是重復測量和使用統(tǒng)計學技術來確定最終結果的不確定性。Tocalibrationaninstrument,thepersondoingthecalibrationshouldconsiderthelimitsof
