![]() ![]() A strong signal from WWVB is required with the clock oriented toward Ft. It may be necessary to disassemble the hands and their gear wheels and re-assemble them in their designated order. Others may have more definitive instructions for the "Sky-Scan" clock.ĭuring the getting in sync period, the hands may move in two or three seconds steps depending on the design of the circuits and mechanics. Then the locking pin removed and the battery inserted, and the clock started to receive the time data stream and allowed to bring the hands in sync with the data stream withing a few minutes. I found in some obscure instructions, a method of "lining-up" the seconds, minute and hour gears to a position where a pin could be inserted through the "stack of gear wheels" to lock the gears, and with the gears locked, the hands could be forced to the proper position. In this way, the whole "musical" group starts out with all the players on the same page of music.so to speak. SkyScan Atomic Clock Indoor Temperature Date Automatic Jumbo LCD Wood NIST WWVB. In the examples I have owned, the hands have to be in a certain position before the battery is inserted. Get the best deals on jumbo atomic clock when you shop the largest online selection at. Synchronizing a data stream to the motor that moves the hands is more like the job of an orchestra leader whose task involves keeping the violins, percussion, brass and bass parts all in harmony. I'm not familiar with the "sky-scan" product. The problem is one of the basic design of using a complex radio signal that is a continuous digital stream of month, day, hour, minute and second and using the continuous stream of data to control a miniature battery-electric motor to make the hands go round. We recommend atomic clocks that can run on electricity and have power backup in batteries in case of a power shortage.Your "atomic clock" is obviously of the analog type instead of digital. For the clocks that run using a power cord, you have to keep them where they can be connected to a plug point, but they will hardly face any power shortage issues. I have a transmitter for a Lacrosse Atomic clock that transmits at 433 MHzs. However, they are easily portable and can be placed anywhere. I have a Sharp Atomic Clock and the transmitter for the external temperature got smashed accidently. Battery-operated atomic clocks require the replacement of the batteries when their efficiency reduces.
