Product overview
SYN5301The type time calibrator is a highly precise time calibrator designed and developed by Xi'an synchronous Electronic Technology Co., Ltd.This equipment is based on the requirements of JJG237-2010 "stopwatch verification regulation", which is a multifunctional, comprehensive time calibration automatic test device. It is used to verify mechanical stopwatch, electronic stopwatch, pointer type electric stopwatch, digital electric stopwatch, digital millisecond meter, and various time meters. By measuring the standard time interval signal, the measured instrument can get the actual measurement value of the standard time interval signal, so as to get the measuring error of the detected instrument and achieve the purpose of verification. It is suitable for the transmission of various kinds of stopwatches, and can set up the standard device of stopwatch calibrator, and carry out verification / calibration for time type instruments.

The equipment combines 4 functions of stopwatch calibrator, day difference meter / calibrator, pointer type electric stopwatch calibrator and standard time interval generator. The quartz crystal oscillator with high stability is used as the time reference, and the 7 inch LCD touch screen is adopted. The large scale integrated circuit FPGA technology is used. The digital control is realized, and the high-precision time interval output is realized. The machine has the advantages of high stability and high accuracy, perfect function, convenient operation and strong anti-interference ability.It can be used for verification of 401/405 electric stopwatch, 407/408 electric stopwatch, 411 digital millisecond meter, 415/417/417B type digital stopwatch and so on at all levels of measurement departments, factories, colleges and scientific research institutions.
