Note: If you find that the bulb does not light up, unscrew the socket, take out the bulb to
check or replace it with a new bulb.

Selection and adjustment of magnification: Before the instrument works, the left and right
objective lenses should be placed in the same magnification file; the objective lens
magnification can be changed by rotating the magnification adjustment knob (8). If you
need to obtain a large field of view, you can screw the 0.4X additional objective lens
(optional) into the screw holes at the lower end of the two zoom objective lenses, and then
refocus.
In order to make the magnification of the left and right objective lenses strictly consistent,
the user needs to perform micro-adjustment of the magnification. The adjustment operation
is as follows: Put the magnification correction plate on the left and right stage respectively,
observe the reticle through the eyepiece, and adjust the focus to make the two reticle
images. The same is clear, move the magnification correction plate so that the reticle is
aligned accordingly. If the magnifications of the two objective lenses are inconsistent, the
reticle in the inspection cannot be all aligned. At this time, rotate the magnification
correction wheel (17) clockwise or counterclockwise to fine-tune the objective lens
magnification. , re-focus until the reticle image is clear, and move the magnification
correction plate to align the reticle again. Repeat this several times to make the left and
right objective lens magnification strictly consistent. The objective lens magnification is
adjusted in the same steps.
5. Adjustment of field of view cutting and comparison ridges: Rotating the field of view
adjustment handwheel (9) can move the comparison ridges continuously, so as to realize
single field of view, cutting field of view, and overlapping field of view observation; Insert
color filters of different colors into the side sockets for better result.
The comparative ridgeline should be a thin, black line. If the ridgeline is wider (that is,
