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.
