Introduction
The calibrator is a precision instrument calibrating mechanicalstopwatch, electronic stopwatch, and 405/407/408/415/417 typepointer electric stopwatch. The SF2001 stopwatch calibrator iscompliant with the stopwatch calibration procedure JJG 237-2010issued by the National Metrological Bureau. It could be used atmetrological department at all levels, factory, institutionsand all research institutes to calibrate electric stopwatch(405,407,408,415/417), mechanical stopwatch anduartz electronic stopwatch. The instrument is fully digitallycontrolled, high reliability,high accuracy, complete functions,convenient operation, and strong anti-interfere
ability.
