Stopwatch calibrator is used to detect the time error of electronic stopwatch, mechanical stopwatch, pointer stopwatch, digital electric stopwatch, digital millisecond meter, timer and other products. The day difference calibrator is used to verify the time error of electronic stopwatch, smart meter, computer motherboard, electronic scale, clock equipment, electronic cash register, quartz clock, temperature controller, timer, timer and other products.

Stopwatch calibrator detector is the standard time interval signal of the measuring instrument to get the actual measurement value, so as to detect the measuring error of the instrument and achieve the purpose of verification. The SYN5301 type time calibrator has functions of stopwatch calibrator, day difference meter / calibrator, pointer type electric stopwatch calibrator, standard time interval generator and so on. The SYN5301 type time calibrator is used to detect stopwatches. The channel 1 and GND of the time calibrator are connected to the input and GND of the fixture respectively. The switch of the clamp can be opened, and the four road can be tested at the same time. Standard time interval detection operation, select single output or dual output, positive pulse or negative pulse, such as selecting a single positive pulse to measure, need BNC to turn banana head connecting line to connect GND terminal of electric stopwatch. The core of BNC corresponds to the red terminal of banana head to connect the air gap terminal of electric stopwatch.

The SYN5302 day difference detector is used to measure the diurnal difference. Through the sensor, the oscillating signal sent by the clock is converted to the electrical signal, and then the deviation of the electric signal period and the nominal value is measured by counting method, thus the daily difference is obtained. SYN5302 day difference calibrator is used to measure the daily difference of electric energy meters, select the daily difference of the energy meter, select the gate time, and then carry out the measurement data. Finally, the PPM, daily difference, monthly difference and annual difference will be calculated according to the measurement results. To measure the daily difference of the electric stopwatch, select the daily difference of the electric stopwatch, select the gate time, and then measure the data. After the measurement is completed, the system will calculate the PPM, the daily difference, the monthly difference and the annual difference based on the measurement results. Frequency measurement operation method, first choose frequency measurement, then choose gate time to measure. The contact sensor operation method first connects the daily difference detector with the sensor base, then places the required detector at the sensor contact point, and moves the instrument to the strongest signal intensity of the calibrator. The USB interface enables U disk data storage.

The SYN5301 type time calibrator and SYN5302 type day difference detector manufactured by Xi'an synchronous Electronic Technology Co., Ltd. are fully functional and can meet the needs of various industries, and can be used for the detection of stopwatches. The standard device of stopwatch calibrator can be established, and time type instruments can be calibrated and calibrated. This equipment is widely used in metrology verification department and product quality inspection organization. Clock manufacturers and smart meter manufacturers.
