3. Unpacking and setup (1) Unpacking ① Take the DR-M2/DR-M4 out of the packing case and check to see whether there is any external damage observed or not. ② Make sure that the following things have been contained in the packing case.
4. Names and functions of main parts (1) Refractometer (Figures 4-1,4-2 and 4-3) Eyepiece For observing the boundary line between light and shade refraction field in the vision. On observing the eyepiece, turn it to bring the cross hairs into focus. The boundary line cannot be seen without sample on the prism.
