1.3 Operation of Microscope

7
First, please choose long shot or flush-way shot, then adjust
the focus button.
(1) Focus way: the focus dial is labeled to indicate the
magnification amount (10x, 40x, and long shot). Rotate the
wheel of focus to position (A) is for long shot, to (B) is low
optical magnification (10x), and to (C)is High optical
magnification (40x). Adjust photograph distance (height) to
get one to ten times of magnification consecutively. Rotate the
dial to right for smaller magnification, and to the left for larger
magnification. You may find symbol represents the
magnification rate. Please see below image, the indicator is
under the position of 10x ( ) magnification.
(2) Horizontal contact: there are two focus points (10x & 40x)
in horizontal-contact observation, slightly tuning theblack
indicator so that to get the clearest image quality

8
(3) Long Shot: Rotate the Focus dial next to 10X‟s right side, then
slightly tuning so that to get the best image. Photography is
same as the way of camera and scene mode is selectable.
[please refer to (B) of item (1) of Section 1.4].
1.4 Microscope Programming Functions
There are 8 function modes in the programming interface.
Press the Function Menu /Delete button to switch functional
modes in the Camera. In other modes, press the button of Preview
Photo /Back to back to the Menu and switch function as
displayed in the following image:

articles with light colors.
(B-5) : Dark Grey mode, for example, the observed
articles with dark colors.
(B-6) : Black mode, for example, the observed
articles with dark black.
(C) Special Effects : press button to choose the
following special effects models in observing model:

11
Normal : general model without any special effect.
Grey Scale : shows by grey scale to simplify and easily
identify images.
Reversed-phase : shows by complementary colors to
strengthen faint-colored or over-lighted image.
Relief : Outstanding show the edge and filter out
non-marked image.
(D) Brightness of Lights : press and to
adjust brightness of lights in the observing model. The
brightness is divided into the following 8 levels:
level 0 (no light)
level 4
level 1
level 5
level 2
level 6
level 3
level 7 (most bright)
(E) Battery Status : the state is divided into three types
including Battery in Using, Battery Charging and USB
Power Supply.
Battery in Using : only use the battery without any
external power supply.
Full
High
Medium
Low
Battery Charging : use USB power supply to charge
the battery. The charging will stop if the battery is full, and
only USB power supply will be used. Power supply applied

12
to charging can be provided by USB power supply device or
USB connection port of computer.
The following images are presented while charging
USB Source : the graphic will be presented under two
circumstances. One is insert USB power supply without
using battery, and the other is insert USB source and use
full-charged.
(F) Optical Digital Magnification : represents current
magnification rate.
The optical zooming rate will be changed while adjusting
the black indicator on the wheel of Focus. Please refer to the
following.
Long Shot
Low Mag.(L)
High Mag.(H)
Digital magnification rate can be adjusted by the buttons of
zoom out ( ) and zoom in ( ). The magnification is
divided into 8 stages and can be up to 4 times with 0.5 times
per stage. The image can be enlarged to 47 times when
combining optical and digital magnifications. The rates at
different stage are as follows:
10x optical rate [10* (1+0.5*stage)]

(H) Alignment in Range : press the button for a long
time to display the sign of alignment in range, and press it
again to shut down the sign. Use the sign to assist in
aligning the observed article.

14
(I) Crossing Alignment : Press the button for a long
time to display the sign of crossing alignment, and press it
again to shut down the sign. Use the sign to show the
position in which the lens of machine is located and make
the alignment more conveniently in observation .
(J) Scale: Press the button (Confirmation button) for a
long time to display the scale, and press it long time again
to shut down the scale. Press the button of without
releasing to select different scales. After selection, release
the button. The two types of scales are showed as follows:
L-shaped Scale
Crossing Scale
The scale might be incorrect because of concaved and
convex observed object making the focusing distance is not
standard. For the standard focus, please use the
flushing-way [Please refer to item (2) of Section 1.3].
The scales will be varied with magnification rates changes.
The unit in the scale is 「μm」. The following scales are
highly precise and provided for the users as references.

The taken photo file name shall note the magnification size
based on the photo taken situation. Ex: “IMG0001_L1.JPG”,
the “L”means optical low magnification. “1”means the
stage of digital enlargement. “IMG0001_H8.JPG”, the “H”
means optical high magnification, “8”means the stage of
digital enlargement. The above file name, capital letter L
means the optical mag 10x, H means 42x. If the
magnification icon shows “…x”which the file name will
not note any L/H since machine is not able to know the
preview situation. Below chart is the FOV (Field of View)

The photo which taken under contacted observation can do
measurement from “Application Program”. The taken photo
image quality will decide the accuracy on measurement. (If the
taken photo is not clear or missing focus, then the measurement
might not be correct.) It is suggested to key in all values from the
look-up table before start measurement.
To begin measurement, please open AP and choose “Measurement
mode”see as below fig.
Then, choose “Setting Ruler”
After enter “Setting Ruler”, please create scale files
according to different optical mag and digital stage
enlargement. The way to create the scale, please refer to
AP manual 5.4.5 ((User's Manual\AP meanual.pdf) inside
the Install CD. After create different scale files, choose the
correct scale according on the taken photo file name to start
measurement.
