(接上期)5.2.3.7时间戳应读取装置的时钟获得时间戳。根据器具的种类或者应用领域,时钟的设置应是法制相关的,需根据应用严重等级(见5.1.3.2.c)采取适当的防护措施。独立计量器具的内置时钟由于没有与全球时钟校对的工具,将会有较大的不确定性。如果特定应用领域测量的时间信息是必不可少的,那么必须通过特定的方法与手段加强内置时钟的可靠
(Continued) 5.2.3.7 Timestamps The timestamps should be read from the device’s clock. Depending on the type of appliance or field of application, the clock settings should be legally relevant and appropriate precautions should be taken according to the application severity level (see 5.1.3.2.c). The built-in clock of independent measuring instruments There is a great deal of uncertainty as there is no tool for proofing with the global clock. If the time information measured in a particular application area is essential, the reliability of the built-in clock must be enhanced by specific methods and means
