1.1 Out of the Box
The DM150-W Microscope comes completely assembled and almost ready to use right out of the box. Remove
the inner packaging from within the box and position so that the packaging prevents the accessories from
falling out when opened. Additional components in the packaging include a main power cable to power the
digital microscope and a WiFi module power cable that will allow you to power the digital camera connect the
microscope to the app on your mobile phone (see section 2.1).
CAUTION: Never lift the microscope by the head. If the head is not properly seated, it can become separated,
causing the body to fall, or otherwise damage the coupling mechanism. During transport, hold the microscope
by the body in an upright position to prevent the head, eyepieces, or other parts from falling.
Packing List:
• 1x DM150-W Microscope
• 1x Main Power Adapter
• 1x USB-C Power Cable
• 1x USB Power Adapter
• 1x Microscope Dust Cover
SECTION 1: UNPACKING THE MICROSCOPE
1.2 The Objective Lenses
The microscope is equipped with three objective lenses which are mounted to a
rotating turret between the head and the specimen stage. Should the lenses be
removed for transport, they are mounted and unmounted by rotating each lens
clockwise or counter-clockwise respectively. The lenses are typically mounted
in order from 4X to 40X, but can be interchanged as desired. This microscope
is compatible with DIN-standard objective lenses, which allows aftermarket
lenses to be used as needed. These lenses must comply with the following
DIN* specications:
• 20.32mm RMS mounting thread
• 160mm mechanical tube-length
• 45mm parfocal distance
*DIN stands for Deutsches Institut für Normung which is a German standards organization. Microscopes
and objective lenses which are DIN compliant will use the aforementioned specications

3.1: The Specimen Stage
The stage has an adjustable height limit. This is used to prevent the stage from
being raised too high which could result in damaging the specimen or even the
objective lenses. The adjustment screw is located on the body just behind the
stage.
Rotate the objective turret until the 40X objective lens is in place. With a
specimen mounted on the stage, slowly raise the stage using the coarse-focus
knob until the specimen is a few millimeters from the lens. Use the ne focus
knob to continue raising the stage until the specimen barely comes in contact
with the lens. The 40X lens has a spring-loaded nose. If the nose begins to
compress, the stage is too high. When the specimen is able to make contact
with the lens without compressing the nose, this is the appropriate maximum
height.
The height-adjustment screw should be tightened to set the stopping position.
If the specimen was too far from the lens, and could not make contact, loosen
the adjustment screw slightly, then continue to make ne focus adjustments
until the specimen is high enough. Once the height is properly set, tighten the
adjustment screw.
3.2: Power
The power switch should be set to the “off” (0) position. Attach the provided
power cable, ensuring that the instrument is not exposed to any environmental
dangers such as moisture or sources of excessive heat such as open ames.
Set the power switch to the “on” (I) position to activate the built-in illumination.
The microscope can also be powered by three AAA batteries. Remove the
bottom cover with a small philips head screwdriver and insert batteries in the
correct orientation. Batteries are not included.
If using rechargeable AAA batteries, the microscope will recharge the batteries
when plugged into an AC outlet using the included power adapter.
SECTION 3: OPERATING THE MICROSCOPE

3.3: Mounting a specimen
This microscope is designed to view translucent specimens mounted primarily
on 3” x 1” glass slides. A metal template with caliper is attached to the top of
the stage. A prepared slide can be placed on the stage by pushing the caliper
lever outward to open the caliper, then sliding the slide in place so the long edge
is ush against the back edge of the template. Gently releasing the caliper will
secure the slide in place.
3.4: Illumination
Turn on the microscope’s illumination by pressing the power switch to the “on”
position. As magnication increases, more light will be necessary to view the
specimen. Use the dial on the microscope’s base to adjust the illuminator’s
brightness as needed. Avoid using the microscope for long durations with
excessive brightness, as this can strain the eyes.
SECTION 3: OPERATING THE MICROSCOPE
3.5: Locating the specimen, and focusing
With the specimen mounted on the stage, and the illuminator turned on, use the stage’s X-Y control knobs under the
right side of the stage to adjust the position of the specimen. The larger knob will move the specimen forward and
backward, while the smaller knob will move the specimen left and right. Sliding the specimen towards the front of
the microscope will result in the viewed image moving in the opposite direction. Use the knobs until the specimen
appears to be centered under the objective lens. This will be the starting point.

Observation should typically begin at the lowest magnication. This provides the broadest view of the specimen.
Rotate the objective turret to set the lowest magnication lens in place.
The stage should be set to a low position when mounting the specimen. Gradually raise the stage using the
coarse-focus knob. If you have already performed the height-limit adjustment, the specimen should come into
focus near the maximum height. Once you begin to see shapes through the eyepieces, use the ne-focus knobs
to adjust the focus until you can see details with clarity. Use the X-Y control knobs to reposition the specimen
until the area of interest is in view. You can increase magnication as needed by rotating the objective turret.
When doing so, it is advisable to watch the lens as it is set in place to ensure it will not collide with the specimen.
Slight adjustments to focus should be made at each magnication, as well as the illuminator’s brightness.
