WSS - 481 the precision of the bimetallic thermometer level is how to divide

In all of the instrument used for measuring, in normal use conditions shown in the accuracy of measurement results is called precision instrument. In industrial measurement, the accuracy of the often said with a precision instrument, precision is great reference error remove & other; ± ” Number and & other; %” Number. Precision measuring instrument is one of the important indicators of quality, our country industrial instruments into 0. 1, 0. 2, 0. 5, 1. 0 and 1. 5, 2. 5, 5. 0 seven grades, and logo on the meter scale or nameplate. Accuracy level customarily called precision level. It WSS - 481 the precision of the bimetallic thermometer level is how to divide? In fact, WSS - 481 bimetallic thermometer precision grade and common measuring instrument is the same, also can say error & plusmn; How much %. Precision grade is it permissible error of the dial scale value by it's percentage, its accuracy level the greater the number of permissible error of dial scale limit value is larger. Range, the greater the same precision level, it measured the absolute value of the temperature the greater the margin of error. 1. Level 5 and 1. Level 0 respectively under normal use, WSS - Bimetallic the permissible error of the thermometer was 481 range & plusmn; 1. 5 and & plusmn; 1. 0%.
