OPERATION INSTRUCTIONS
Preparation before Measurement
Place the instrument on the working table and adjust the inclination so that the operator is able to
make the measurement comfortably.
Connect with the mains.
Before measurement, visibility of the eyepiece shall be regulated in order to obtain accurate
results. While observing the black cross dividing line of the (8) eyepiece reticule, rotate the
eyepiece cover counterclockwise entirely. Then slowly turn the eyepiece cover clockwise until
the black cross becomes clearest. The eyepiece is now in focus.
Rotate the diopter measuring handwheel to regulate the scale interval to zero position. Observe
the green division line of (3) marker reticule in the view field of the eyepiece. The green dividing
line should now be clearest.
