电子远传水表行业标准CJ/T224-2012规定了直读式电子远传水表进行机电转换可靠性试验,即将被试水表与匹配的专用试验设备相连接,试验至少选择在各字轮进位条件最不利的情况下进行,如从9跳变至0的阶段,跳变延续过程要求不少于3个字。试验在跳变发生前延续到发生后分别读取机械指示装置的读数和电子读数,将两组数值进行比较,判断其相同性和关联性,要求电子读数和机械指示装置读数一致,不出现错码。
Electronic remote meter industry standard CJ / T224-2012 provides direct reading electronic remote meter for electromechanical conversion reliability test, the test meter is about to be connected with the matching special test equipment, the test at least choose the character round carry conditions The most unfavorable circumstances, such as jumping from 9 to 0, the transition process requires a minimum of 3 words. The test was repeated before the occurrence of the jump to read the mechanical indicator readings and electronic readings, the two sets of numerical comparison to determine the sameness and relevance of electronic readings and mechanical indicating device readings consistent, does not appear wrong code.
