Beat Numbers (Frequency Numbers)
1.Automatic
The following beat numbers are selected by automatic selection mode:
12000,14400,18000,19800,21600,25200,28800,36000,43200
(If the tested beat is not in automatically selection, the instrument will display the closest beat number, but the test result is not correct.
At this time, use the manual mode to select the relative beat.)
2.Manual selection
It can selected out the beat number that Automatic select can not identify and rare beat number.
The following beat are selected by Manual selection mode:
3600,6000,7200,7380,7440,7800,9000,9100,10800,11880,12000,12342,12480,12600,13320,13440,13500,14000,14040,14160,14200,14280,14400,14520,14580,14760,14850,15000,15360,15600,16200,16320,16800,17196,17258,17280,17786,17897,18000,18049,18514,19332,19440,19800,20160,20222,20944,21000,21031,21306,21600,25200,28800,32400,36000,43200
Lift Angle
The lift angle is 52° for many common movements, therefore the lift angle value of instrument for factory is set to 52°. This value is required to calculate the amplitude and must be selected according to the watch movement. The lift angle can be set to between 30°and 70°
Period
The measuring period selectable:2s,4s,8s,10s,20s,30s,60s Use to recalculate the average values of the test result.
