Assembly
Aaching the Monitor
Tilt the mounng bracket back 90 degrees so it is poinng up. Place the monitor in front of the bracket with the screen
facing the front of the microscope. Align the holes in the back of the monitor with the holes in the bracket. Insert each of
the three mounng screws, and rotate clockwise unl they are securely fastened.
Two cables are aached to the microscope behind the bracket, including HDMI and power. Insert each cable into its
respecve port on the monitor.

USB Devices
The microscope has two USB ports on its right side. These can be used to aach USB devices such as the included mouse,
a keyboard, and storage devices. A USB port expander is included in case more than two devices would be used simulta-
neously.
Wireless Mouse
The included mouse is required to navigate the microscope’s soware. Remove the baery cover on the underside of the
mouse, remove any insulator strip if present, then replace the cover. A USB dongle will be inserted into a dummy slot on
the underside of the mouse. Remove the dongle, and insert it into an available USB port on the microscope. Locate the
power switch on the underside of the mouse, and move it to the “ON” posion.
Storage Devices
An external storage device is required to save photos and other les. This microscope is compable with various devices
including thumb drives and card readers. Compable storage devices will be automacally detected when aached.

Aaching the 3D Aachment
The oponal 3D aachment is designed to mount to the objecve lens’ housing. The 3D aachment’s mounng ring has
female threads which will screw onto the objecve housing’s male threads. Guide the 3D aachment’s mounng ring
upward onto the objecve housing, then rotate to the right using the knurled poron of the ring. Connue rotang unl
the ring is fully mounted. Do not applying excessive pressure, otherwise the aachment will be dicult to remove. When
securely mounted, the aachment’s slider should rotate freely.

Operaon
Focusing
Each side of the microscope’s focusing column is equipped with a focusing knob. Rotang either knob will raise or lower
the microscope’s head.
Tension can be adjusted for the knobs by securing one in place, then rotang the other. Rotang clockwise will increase
tension, and counter-clockwise will decrease tension.
Magnicaon
Zoom Dial
The zoom dial controls the magnicaon of the microscope by adjusng the internal zoom mechanism. The dial can be
rotated in a connuous movement from the 0.7X seng to the 4.5X seng. Key magnicaons have detents (mechanical
catches) which allow the dial to “click” into place. This allows you to set magnicaons more precisely when performing
measurements. Rotang the dial clockwise will decrease the magnicaon, and rotang the dial counter-clockwise will
increase the magnicaon.

Opcal Magnicaon
This microscope uses a combinaon of a xed-magnicaon 1X objecve lens and zoom opcs to provide its 0.7X-4.5X
magnicaon range. This is the opcal magnicaon range which is typically listed. An addional 0.35X magnicaon
stage is used to compensate for the format of the digital image sensor. This document refers to this stage as integrated
reducon, since the purpose is to reduce the size of the image to beer t the specic image sensor. While this reduc-
on stage modies the overall magnicaon prior to being imaged, it is typically not referenced in listed magnicaons
due to its associaon with the image sensor. However, it should be used when calculang total system magnicaon as
described in the following secon about monitor magnicaon.
Monitor Magnicaon
Since the image displayed on the monitor is larger than the camera’s sensor, the monitor is considered to have its own
magnicaon referred to as monitor magnicaon. The magnicaon factor is calculated by dividing the diagonal of the
on-screen image by the diagonal of the camera’s sensor.
294mm/6.39mm = 46
Total system magnicaon includes all of these factors, and can be calculated using the formula:
MOBJ x MRED x MMON = MTOT
where MOBJ is objecve magnicaon, MRED is integrated reducon, MMON is monitor magnicaon, and MTOT is total mag-
nicaon. The low and high magnicaons would be as follow:
0.7 x 0.35 x 46 = 11.27
4.5 x 0.35 x 46 = 72.45

DM745-HDM11 User Guide

Illuminaon
This microscope is equipped with an LED ring light to provide illuminaon. The ring light can be removed to expose the
objecve lens housing by simultaneously pulling downward on the le and right sides. When reaaching, be sure to align
the two electrical contact on the top of the ring light with the pins on the underside of the microscope head.
The ring light’s intensity is controlled by a wheel on the right side of the microscope. Rotang the wheel counter-clock-
wise will increase the intensity, and rotang clockwise will decrease intensity.
3D Aachment
The 3D aachment can be used to alter the angle-of-view, allowing you to view an object from oblique angles without
moving the object. The 3D aachment consists of a mounng ring and a slider. The slider can be posioned for normal
viewing or 3D viewing. The open posion removes the slider’s mirrors from the opcal path allowing you to view normal-
ly. The engaged posion places a mirror directly under the microscope’s objecve lens, relaying an oblique image from
the second mirror. When changing the posion of the slider, use the metal posioning rod to avoid contaminang the
mirrors. When engaged, the aachment can be rotated 270° without obstrucon. Use the posioning rod or an outer
edge of the slider when rotang to avoid contaminang the mirrors.

Soware
The DM745-HDM11 uses internal soware to manage camera and display sengs, as well as to perform image-capture
and measuring funcons. All of these funcons are accessed from the on-screen console. The console is divided into four
secons including Calibraon, Main Tools, Assist Tools, and a measurements log.

DM745-HDM11 User Guide

Calibraon
The calibraon secon is used to select precalibrated magnicaon proles or to dene custom proles. A magnicaon
prole denes the relaonship between camera pixels and real units of measure such as millimeters. Once this relaon-
ship is dened, any shape drawn on the screen will provide accurate measurements by translang the number of pixels
into the desired unit of measure.
Calibraon Tool
The calibraon tool has two opons: “Line Calibraon” and “Calibraon by Circle”. To select the desired tool, click on the
down arrow next to the icon.
Proles
Proles are predened for key magnicaons, and can be selected for use with the corresponding magnicaons to per-
form accurate measurement funcons. When using any magnicaon which is not already have a prole, the calibraon
process must be performed to produce accurate results.
Units
Units denes the measurement unit to be displayed when performing measuring funcons.
Line Calibraon
To perform the calibraon process, a ruler will be needed for reference. For low magnicaons, a ruler with millimeter
graduaons is usually adequate. For high magnicaons, a ruler with ner graduaons may be needed, such as a mi-
crometer slide. Place the ruler under the microscope’s lens so it can be viewed on the screen. The ruler needs to be in
clear focus with mulple, clearly-disnguishable graduaons visible on the screen.
Click on the ruler icon in the main panel’s calibraon secon. Using this tool, a line will be drawn over the image of the
ruler. Click the le mouse buon to create the rst anchor point. As the cursor is moved, a line will be displayed. The line
should span as many readable graduaons as possible, and should be parallel to the ruler’s edge to improve the preci-
sion. Move the cursor along the image of the ruler unl it has spanned an adequate number of graduaons, then click
the le mouse buon again to create the second anchor point. A popup window will be displayed. Enter a name for the
prole, the length of the measurement, and the current magnicaon. If you are not using a keyboard, double-click on
each appropriate eld to enable the on-screen keyboard. Once nished with the calibraon, click on any measurement
tool to use the prole.
Once saved, the prole will be listed in the main panel’s drop-down selector. With the prole selected, you can select the
desired unit of measure to display on-screen measurements in that unit.
Calibraon by Circle
This calibraon is similar to line calibraon, except it uses a circle which can be useful when referencing premeasured
diameters. Click the le mouse buon to create the rst anchor point on the edge of the reference circle. As the cursor is
moved, a line will be displayed. Move the cursor to the opposite side of the circle, then click the le mouse buon again
to create the second anchor point. A circle will now be displayed. Move the cursor to enlarge or reduce the size of the
circle. Once the circle is properly sized, click the le mouse buon. A popup window will be displayed. Enter a name for
the prole, the length of the measurement, and the current magnicaon. If you are not using a keyboard, double-click
on each appropriate eld to enable the on-screen keyboard. Once nished with the calibraon, click on any measure-
ment tool to use the prole.
Once saved, the prole will be listed in the main panel’s drop-down selector. With the prole selected, you can select the
desired unit of measure to display on-screen measurements in that unit.

Image Exposure
Manual Exposure
The brightness seng is used to manually control the amount of light captured by the imaging device. Manual control is
preferable when imaging light or dark specimens which do not appear properly exposed when using auto exposure.
Auto Exposure
Auto exposure automacally adjusts the brightness of the image by calculang an average of light levels in the viewable
area. The process aempts to adjust the brightness level unl the average is approximately middle grey.
Color
White Balance
The color of an object is inuenced by the color of light reecng o of it or passing through it. Dierent light sources
produce light with dierent color-biases. Common examples are incandescent lamps which typically produce warm
colors compared to uorescent or LED lamps which produce cooler colors. This sort of bias is referred to as color tem-
perature. Due to this phenomenon, a white object may appear slightly yellow in morning sunlight, and slightly blue in
aernoon shade. To compensate for these variaons, digital imaging devices can process images using what is called
“white balance.” The white balance process shis colors based on the color of the light source, with the goal of produc-
ing a more neutral white or grey.
