Introduction
The calibrator is a precision instrument calibrating mechanicalwatch, electronic watch, and 405/407/408/415/417 type pointerelectric watch. The SF2001 watch calibrator ispliant with thewatch calibration procedure JJG 237-2010 issued by the NationalMetrological Bureau. It could beed at metrological department at alllevels, factory, institutions and all research institutes tocalibrate electric watch (405,407,408,415/417), mechanical watchand digital quartz electronic watch. The instrument is fully digitallycontrolled, high reliability,high uracy,plete functions, convenieeration, and strong anti-interfere
ability.
