SZE-02 high-precision digital speed gun is the place for the standard test equipment developed for new products. High measurement accuracy, either as a dedicated calibrator, also as a general indicator to use high-precision rotational speed. Users can sample time, pulses per revolution, setting the standard parameters such as speed. All the parameter settings and function selection can be carried out through the front panel touch switch control. Simple structure, reliable performance, simple and beautiful appearance. In addition, the instrument can be in accordance with JJG326-83 "standard transfer speed device test procedures", the data processing and processing through the printer to print out the results. Apply to purchase SZJ-3, 4 users, as test its accuracy using. Special specification order is acceptable, that I plant the highest precision digital instrument.

□ Work
The latest instrument used as the main control chip microcontroller using its internal timer T2 capture the unique work to improve the sampling accuracy, In addition, the instrument used with a constant temperature within the crystal cover crystal, thereby reducing the temperature measurement accuracy: as a laboratory test of the instrument, SZE-02 can sample time, number of pulses per revolution, the standard transfer values and other parameters set, all parameter settings and function selection can be through the front panel touch switch control, with the traditional finger round dial set comparison, with simple structure, reliable performance, low cost, beautiful appearance
