The SYN5302 type day difference calibrator is a multi-function calibrator designed, developed and manufactured according to the verification regulation of JJG 488-2018 instantaneous diurnal difference meter. The method of measuring the diurnal difference of the day difference detector is to transform the oscillating signal from the clock to the corresponding electrical signal by using the sensor. The difference between the period of the electrical signal and the nominal value is measured by counting method, and the daily difference is calculated. It can not only measure the electronic products of the built-in 32768Hz crystal oscillator, but also directly measure the clock error of the smart meter which outputs the 1Hz, and at the same time, it can also test the frequency accuracy of the pulse signal.

The day difference detector has the function of checking the electronic clock, smart meter, computer motherboard, electronic scale, clock equipment, electronic cash register, quartz clock, temperature controller, timer, timer and other timing products. It is widely used in metrology verification department, product quality inspection organization, clock production enterprise and intelligent electric meter production enterprise.
