0.3125----16 times of optical magnification
Concrete operations code is as follows：
1st, support 15, circuit, light unit 103, camera lens, industrial camera 6, collection, control system are checked
1st, support 15, circuit, light unit 103, camera lens, industrial camera 6, collection, control system are checked；
2nd, white balance adjusting：White panel is placed in field range, displacement power supply, light power, type coaxial photoelectric is opened
Source, by axis light, upper ring light, fill-in light, lower ring light, backlight is fully open and adjusts to most bright；Click on white balance once.
At this moment it is the white balance matching that optics, camera lens, camera and software systems are carried out；Click can once be completed.It is then turned off same
Axle photoelectric source, light power, into capture program；
3rd, picture is gathered：
Visual field is adjusted：By X-axis displacement, field range is adjusted to need mirror by Y-axis displacement and Z axis displacement switch and knob
Other region；0.25 times of camera lens is installed in camera lens front portion, regulation zoom camera lens passes through displacement switch and rotation to 0.7 times of position
Button adjusts object distance to 325 ± 2mm positions, about in Z-direction appropriate location, opens axis light power supply, light power.According to ring
Border light field regulation intensity of light, untill having a clear handwriting；
Light field is adjusted：Open axis light power supply, light power.Adjust ring light knob in axis light knob, regulation, regulation
Lower ring light knob, adjusts fill-in light knob, adjusts backlight knob.Distribution of light intensity is set to match with multiplication factor, visual field collection,
The light field of the small needs of multiplication factor is just weak, and the light field of the big needs of multiplication factor is just strong, when light field adjusts not enough moment regulation exposure
Time, untill reaching and have a clear handwriting；
Zoom is adjusted：Adjust zoom camera lens knob from 0.7 times of position to 4.5 times of positions, regulation Z axis position, and with closing light
Field control, gradually strengthens intensity of illumination, to person's handwriting it is substantially clear when, regulation zoom camera lens vernier knob to clearly untill；
Picture is stored：Picture storage format has three kinds of modes, without graticule, storage tape cross hair, storage tape grid mark
Line.Click on and preserve picture, then preserve without graticule picture.In order to which storage spider, or storage can be clicked untill determining tag slot
Grid, then puts save button；
4th, light power is closed, rotation zoom camera lens vernier knob stretches out object lens, changes 0.5 times of camera lens, regulating step
It is identical with the 4th step；
5th, light power is closed, rotation zoom camera lens vernier knob stretches out object lens, takes out 0.5 times of camera lens, at this moment object lens
It is identical with the 4th step for 1 times of regulating step；
6th, light power is closed, rotation zoom camera lens vernier knob stretches out object lens, changes 2 times of camera lenses, and regulating step is same
4th step is identical.The smaller 0.1mm of this step depth of field is noted, it is necessary to which regulation manually, only focus controlling is in depth of field size range
When, picture collection can be only achieved clearly degree.Manually regulation when should close displacement power switch, prevent stepping motor rotor and
The magnetic force of stator is away from interference.Automatically control as the field positions needed for camera lens quickly can only be moved to by a part, fine scape
Deep regulation needs regulation manually；
7th, identification finishes closing power supply, and camera lens is taken out into mounted box, protects camera lens.
