Function and configuration introduction 1. Timing: controlled and managed by microcomputer on screen display with two-hand run, and closed-loop control of primary-secondary clock system to keep synchronization run of secondary clock and primary clock. 2. Movement: apply clock movement of Compas worm gear, *5# steel of quenching treatment to fit in all kinds of ugly environment with durable service, and marching type motor drive to output great moment of force. The service time of the movement shall reach *0 years. 3. Lighting: lighting with fluorescent lamp rear projection and the turn-on and turn-off time are controlled by the automatic system. 4. GPS calibration function: connect the satellite signal receiving device to the computer center and compare and calibrate the primary clock with the standard time isolated by the computer to make sure the synchronization of turret clock and standard time with no accumulative error. 5. Automatic tracking function: when AC black out, the primary clock is of automatic memory, and it shall automatically track standard time without calibration in *0 years. 6. Humidity resistance: the complete machine is of great characteristics such as anti-thunder, rain-proof, humidity resistance, and weather-proof. 7. Power supply: **0V±*0% of voltage, *0HZ±2% of frequency and ***0W of power. Jinan Kangdashi Watch & Clock Development Co., Ltd. is a professional clock manufacturer in China, and specializes in the design and manufacture of wide collection of clocks for special uses. Our main products include tower clocks, cuckoo tower clocks, school wall clocks, pillar clocks, advertising clocks, digital clocks, world time clocks and floral clocks. Meanwhile, we provide all kinds of custom-made clocks according to your special requirement and install the clocks on your buildings. Features of Jinan Kangdashi Clock Development Co., Ltd clocks1. We select AT*9C*2 micro processor as controller, ensuring stable operation.2. Our Architectural Large Quartz Clocks meet to QBT********5 national standards.3. Quartz oscillator vibrates at a precisely constant frequency, with an accuracy of 3 seconds in a month; our clock works with the GPS time signals received from the satellite.4. Our tower clock mechanism is made out of self-developed patented mechanism. One main clock controls other clocks by mechanical connection to ensure the synchronization of all clocks in different sides.5. Accurate timekeeping. The timer interval can be arbitrarily set and music and voice can be set per your choice.6. Lighting intervals can be arbitrarily set which is accurate and reliable.7. All Our Tower clocks as designed to work on **0.Volts AC. Our clocks will be provided with a battery back-up for *2 Hours. Our clocks will switch over to DC battery power automatically as soon as the power fails. Back-up power supply has automatic charge-discharge protection which improves the battery lifetime. Meanwhile, our clocks have memory modules. Once the clock gets the AC Power the clock will automatically resume the right time automatically. There is no need of time setting after the power cuts.Our clocks are widely used all over the country, such as one sided and two sided wall clocks in many colleges and school buildings, four sided tower clocks on hotel buildings, churches, and factories and cuckoo tower clocks on playground buildings.By virtue of high quality, our products have gained ISO***1 certification. It is our commitment to improve our product quality and provide efficient, sound and fast service for all customers. We welcome all customers for more information about our wide collection of clocks.
