How to find the clear first line of capillary in finger nail.

Step 1…Put the cedar oil on the verge of the finger and skin of the ring finger as bellow, put the verge of finger directly under the light source ( If there is no Cedar oil then please use baby oil or olive oil instead )

Step 2. Rotate the coarse handwheel to see the picture as bellow. The bigger one is the coarse adjustable wheel and the small wheel is the fine handwheel

Step 3. Just the X-Y wheel to get a correct position of the first line of the vessel(capillary tube) and then adjust the fine coarse handwheel to get a clear picture of the vessel. Usually we observe the first line of vessels which is large and obvious. So try to find the first line of vessels by rotating the X-Y wheel to change the position of the finger. And finally rotate the fine handwheel (the position in showed on step 2) to get a clear picture of the vessels


Step 4 If. there is spot on the screen, rotate the camera right and left to eliminate it.
