1984年4月23日～4月25日在杭州召开了浙江省青田真空仪表厂生产的 QLJ-1型冷阴极中真空规鉴定会。来自全国各地的40多名代表对该厂产品进行了技术鉴定。鉴定结果认为此规达到了设计指标,可以批量生产。该规的设计指标是:1.测量范围为1×10~(-5)～1×10~(-1)托:2.最大误差是偏离标准曲线不大于100%或不小于—80%;3.下限激发时间不大于30秒;4.冷规漏气率不大于10~(-6)托·升/秒;5.漏电流不大于电表刻度±1%;6.规管工作电压是阴极对地为—1.9千伏,稳定度优于±1%。
April 23, 1984 to April 25 held in Hangzhou, Zhejiang Qingtian vacuum instrument factory production QLJ-1-type cold cathode in the vacuum gauge identification meeting. Over 40 delegates from all over the country conducted technical appraisals on the products of the factory. The results of the assessment that the rules reached the design specifications, mass production. The rules of the design indicators are: 1. Measuring range of 1 × 10 -5 ~ 1 × 10 -1 Torr: 2. The maximum deviation is not more than 100% deviation from the standard curve or not less than -80%; 3. The lower limit excitation time is not more than 30 seconds; 4. The cold gauge leak rate is not more than 10 ~ (-6) Torr · L / s; 5. Leakage current is not greater than ± 1% of the meter scale; The cathode to ground is -1.9 kV, the stability is better than ± 1%.
