Count the number of mm of the stage micrometer (x) corresponding to a certain
number of intervals on the eyepiece reticule (y).
In the example: 7.8mm on the stage micrometer corresponds to 120 intervals on the
eyepiece reticule.
Calibration formula:
Calibration value
(in the example):
7.8mm on the stage micrometer corresponds to 120 intervals on the reticule
mm = 0.065mm calibration value
8.2.2. Distance measurement
Swivel the pivot arm to the 90° position (chapter 8.1.) Set the zoom of the stereo
microscope to a calibrated magnification (the highest value will provide
measurements that are more accurate). It might happen that the pitch line of the
reticule is not coincident with the cutting edge. Use the setscrews of the movable
objective adaptor to set the pitch line coincident to the cutting edge.
Measuring (in the example):
reading on the reticule: e.g. 2 intervals
2 intervals x 0.065mm = 0.13mm (length of measurement distance)
Once the distance is measured, the specimen pivot arm can be swivelled into the
processing position (indication 0) to its end stop. The measured value can than be
removed by advancing the tool correspondingly. One click stop of the feed hand
wheel advances the tool according the selected step size.
