★ Turn the tension adjustment collar①with your
fingers.When the collar is turned in the direction
of the arrow, thetension of the coarse adjustment
knob② increases. Turning the collar in the opposite
direction decreases the tension.
If the nosepiece descends on its own or if the
specimen gets out of focus quickly even when it is
brought into focus using the fine adjustment
knob③, it means the tension of the coarse
adjustment knob is too low. Turn the collar in the
direction of the arrow to increase the tension.
