2-2InstallationSteps BS-6020RF⁄TRF

2-2-1 Installing the Mechanical

Stage Support Device

1. Before installing the device, be sure to

adjust the coarse focus knob①. Make

the guide board ②down to the lowest

position, so you can install the

mechanical stage support device easily.

2. Hold on the mechanical stage support

device (Fig. 2), place it from the top of

the guide board (Fig.1), let the device

(Fig.2) falling free until it reach the limit

position. Use the hexagon wrench screw

down the locking block ③, make the

stage support device and the guide board

fixed together(Fig.3).

The mechanical stage⑤have been

adjusted horizontally and fixed

together before leaving factory. Do

not disassembly unless necessary,

that may affect the observation

precision of the instrument.

2-2-2 Installing the reflected light

brightfield/darkfield illuminator

1. Installing the reflected light illuminator

(Fig.4) on the head of

microscope body(Fig. 5), and turn to a

proper position, then screw down the bolt

⑥to fix it.

2-2-3 Installing the Video Port

1. Insert the video port (Fig.6) into the

illuminator (Fig. 4), then screw down

the bolt to fix it.

1. Adjusting the coarse focus knob until the

support device of the mechanical stage

reach its low limit position.

2. Wresting the lowest magnification

objective onto the nosepiece from the

left or the right side, then push the

nosepiece clockwise, then place other

objectives by the sequence of low to

high magnification (Fig.7).

Installing objective this way will make

the change of magnification to be easier

while in using.
