1. Introduction
BPM-620 portable metallographic microscope is convenient for on-site materials structure
identification of various metal and alloy which can not be identified by making samples. It can be
widely used in the plant metallographic Laboratories for the metal materials analysis, materials
processing identification and the metallographic structure analysis. It also can be used for jade,
porcelain, bronze surface tissue structure observation and analysis.
BPM-602 uses LED vertical illumination, it is portable, convenient to use and safety. Optional
magnetic base is available, convenient for observation of large pipes and equipments.
This illumination can be used continuously for forty hours after a charge, long working time, save
energy, temperature rise is small, there is not much heat, safe to use.
Digital cameras can be used with this microscope to facilitate the acquisition, preservation and
image analysis.
Magnetic Base(optional)

5. Operation
According to the diagram shows, plug the eyepiece 10# into the eyepiece tube 9#, screw object
lens 1# into the lens holder 2#. When install the objective, users can remove the microscope base
16# and then screw it on. Then place the treated metallographic specimen in the microscope
base and adjust the focus knob to start observation, please turn on the power switch 12#,
brightness can be adjusted freely according to needs.
The instrument adopts DC 3.6V lighting power, LED lamp, compact structure, safe and
convenient.
The microscope can work for five days after one time electric charge, there is an indicator light for

BestScope International Limited
charging, red light indicates charging status, green light means power is sufficient, the charging
time is about 2 to 3 hours.(the general charging time can not be more than 8 hours)
The electrical part of the microscope is safe, reliable and seldom has failure. If the indicating light
can not on, the LED illumination also can not work even after charging. Please remove the
electrical part from the microscope and send it back to the manufacture for repairing. Please do
not t repair by yourself to prevent accidents.
6. Maintenance
(1) After using of eyepiece and the objective lens, please use absorbent cotton or wiping paper
with a small amount of mixed ether and alcohol (3:1) to gently wipe the surface dust and dirt.
(2) To prevent dust effects the microscope imaging quality, please use a plastic bag to cover the
microscope when it is not in use.
(3) Please avoid the microscope to contact with acid, alkaline gas, the microscope also should not
be placed in damp, cold and hot environment so as not to affect the optical body quality and the
service life of electrical parts.
(4) The lubricant oil in the microscope is special, generally do not have to add, after long-term
use, the oil may dry and no lubrication. In order to guarantee the quality and precision of the
instrument, please send to the microscope back to the factory for repairing or contact the
manufacturer.
