How to use measurement & calibration function
1 Point the magnifier onto a target object e.g. a ruler; rotate the focus
wheel to get a clear focus.
2 When the focus at the clearest point, take a snapshot
3 Watch the calibration at the lower-end of the focus wheel; note down
the magnification value that corresponds to the indicator marker on
the magnifier body a shown below. That value is the magnification at
which the focus got and the photo taken. (This is very important,
since only with the magnification ration noted down, can the object
size be worked out at later steps!!)
4 Open the captured photo double clicking on the thumbnail. A preview
