Setting The Shutter Speed - Sharp IV-S30 User Manual

[2] Setting the shutter speed

The shutter speed can be set independently for each object type.
Since the shutter speed can be set continuously in the range of 1/30 to 1/10,000 of a second, very fine
adjustment is possible.
- If you want to measure moving objects and increase the image processing speed, set the shutter speed
to around 1/1000 or 1/2000 seconds. However, if you use a faster shutter speed than you need, very
bright lights will be necessary, and bright lighting is not economical.
- For details about the relationship between the brightness of objects (objects to be measured) and the
shutter speed, see IV-S30 User's Manual (Introduction and Hardware) "5-1 [2] Illumination and shutter
speed."
[Example]
- When the shutter speed is slow
(1/60 of a second)
The object is blurred across the screen.
