Setting The Shutter Speed - Sharp IV-S30J User Manual

Setting Measurement Conditions

[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-S30J User's Manual (Introduction and Hardware) "5-1 [2] Illumination and
shutter speed."
