The scale is placed in the plane of the field diaphragm with a division of 0.1mm. The eyepiece with a scale is installed instead of a standard 10x eyepiece. A paired eyepiece without a scale is installed in the second eyepiece tube.\u003c\/p\u003e \u003cp\u003eThe eyepiece is compatible with microscopes that have a 30mm eyepiece tube.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSetting up\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eBefore taking measurements  the eyepiece scale must be calibrated for each objective that will be used. It requires a calibration slide – a stage micrometer with a scale. The minimum division is 0.01mm. The slide should be placed on the stage and the microscope should be focused on the scale. The eyepiece should be rotated in the eyepiece tube until the scales of a slide and an eyepiece are aligned parallel to each other.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCalculation of the eyepiece scale value for each objective\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eIf you use low-magnification objectives  you should calculate how many divisions of the eyepiece scale fit into the slide scale. If you use medium and high-magnification objectives  you should calculate how many divisions of the slide fit into the scale of the eyepiece.\u003c\/p\u003e \u003cp\u003eCalculation for each objective is carried out according to the formula: Е = ТL\/A  where E – eyepiece division value Т – stage division value specified on the stage micrometer (0.01mm) L – number of stage micrometer divisions A – number of eyepiece divisions.\u003c\/p\u003e \u003cp\u003eThe resulting values of the eyepiece scale division for each objective shall be recorded.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCalculating the true linear size of an object\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eWhen measuring an object  first you should count the number of eyepiece scale divisions that the object covers. The result is multiplied by the scale value previously calculated for the selected objective.
