Watch the swing when the test instruments(2)

Watch the swing when the test instruments, there are several important and relevant indicators.

 

(C) the minimum elevation of 24-hour swing: go watch 24 hours after the fact, the vertical plane (position of the general election to the left) can not be less than the minimum 180-degree swing. Watch in high swing low swing than the case when the performance is better, especially for a calendar attachment watch, 24-hour minimum elevation requirement is particularly important swing.

 

Watch swing amplitude measurement instrument is generally used, the Swiss produced AM201 early and GD-50 and other models. It is the use of so-called "base angle method" to measure, so be sure to choose the measurement a good test before the appropriate balance wheel watch rise angle.

 

Watch in the use of detection equipment, a complete detection unit requires calibration instruments and amplitude analyzer. Previous watch repair, we saw the table with a school instrument, only watch factory in order to see the amplitude of the instrument.

 

That it is generally attached importance only to watch the speed accuracy, and swing and accuracy are equally important and interrelated technical specifications of a bad swing, drop too much difference between peace and stand watch, will certainly go bad.

 

Especially in the calibration of the balance wheel balance, adjust the position error, it must be light swing, swing the concept of maintenance personnel required a higher theoretical level watches.
