What is the allowable error of electronic crane scale?
Electronic hanging scale is one of the measurement instruments used in trade settlement. The data accuracy is directly related to the consumers and the interests of the state. Therefore, on the basis of verification regulation for verification, to ensure the accuracy and reliability of electronic hanging scale value is very important.
Electronic hanging scale belongs to non automatic weighing instrument, in accordance with the accuracy grade OIML seventy-sixth ≤ non automatic weighing instrument ≥ international recommendations allow error requirements. China's 1997 released JJG539 1997 ≤ digital indicating scale ≥. The maximum permissible error in electronic hanging scale table.
m（To test for dividing the value E） The maximum permissible error（mpe） Accuracy grade The general accuracy grade For the first time, then the verification test Use of the test 0≤m≤500 0≤m≤50 ±0.5e ±1.0e 500≤m≤2000 50≤m≤200 ±1.0e ±2.0e 2000≤m≤10000 200≤m≤1000 ±1.5e ±3.0e
