4-1-1 Turning on the lamp

  (

fig.16

 

 

Connect the power, turn on the main 

switch

(shown on the fig.16)which on the bottom 

side of the base to “

”(on).

 

4-1-2 Adjusting the brightness

  (

fig.17

 

 

Turning the brightness adjustment knob 

clockwise, the voltage raise, and the brightness 
strengthen; whereas turning at the contra direction, 
the voltage decline, and the brightness weaken. 

◎ 

Using the lamp in a low voltage 

condition, will prolong the service life.

 

4-1-3  Adjusting the Tension Adjustment 
Collar

fig.18

 

 

The tight tension of the coarse focus knob 

had 

already adjusted before leaving factory.

 

 How to adjust the tight tension 

Turning the tension adjustment collar 

. while 

revolving at the direction which shown by the 
arrowhead on the figure, the tight tension of the coarse 
focus knob

 is increasing

and if at the contra 

direction ,the tight tension will decline. 

If the nosepiece dropped automatically, or the 

specimen defocused soon even you focus with the 
fine focus knob

. It means the coarse focus knob 

is too loose,    you should screw it down at the 
direction shown by the arrowhead in the figure18.
