4 OPERATION SWITCHING O N T HE I LLUM I N ATI O N Before switching on the ON/OFF switch, make sure that the input voltage of the microscope power supply matches the local mains voltage. If not, do not switch on the microscope. Improper input voltage may result in a short circuit or fire. Make sure that the power cord is plugged into the connector on the back panel of the microscope base.
FOC US I NG ON T H E S P EC IM EN Set the minimum magnification of the 0.67x objective by rotating the zoom knob 8 (Fig. 1). The zoom knobs are on both sides of the microscope head. Rotate the knob 1 (Fig.
CALCUL ATIN G T H E TOTAL M AGN I F I CATI ON The total magnification is the eyepiece power multiplied by the objective power. The objective magnification corresponds to the number on the knob 2 (Fig. 3) located opposite the line. You should also consider the magnification of the auxiliary objective lens, if you use it.
We recommend entering the obtained data in a size chart: Objective magnification Eyepiece division value 0.67 Using these data to determine the actual linear size of the specimen, you just need to count the number of divisions of the eyepiece scale aligned with the area of the specimen being measured, and multiply this number by the scale division value specified in this table.
USI N G THE CA LIB RAT IO N S LI DE WIT H A CA M ER A The calibration slide (stage micrometer) is used to calibrate the image analysis software for measurements in actual units. In the calibration mode, you should capture an image of the micrometer scale with every objective magnification and indicate the known distance.
