[usage]

1. Pull the battery isolation bar.

4. Turn on the side LED light switch, place the viewing object in the center of the shield, aim the eyes at the eyepiece, and adjust the focusing knob to the required multiple and clarity until it is clear.

5,Paper and printing outlets used for jewelry appraisal, finance, tax, philately and electronic industry to observe banknotes, bills, certificates, postal, COINS and CARDS. Can accurately and quickly identify counterfeit money, high resolution. Violet lamp detects inexact, can identify accurately with this instrument, true renminbi is in this microscope graph grain is clear, line coherent, false banknote graph grain is formed by dot shape more, line shows dot shape incoherent, colour and lustre is shallow, fuzzy, without stereo feeling.

6, used in the jewelry industry, can observe the inner structure of gemstones, molecular arrangement of sections, and can analyze and identify ore samples and cultural relics.

7, used in the printing industry, can be refined version, color correction and dot, edge extension observation, can accurately measure the silk mesh, dot size, overprinter error, etc.

8. Used in textile industry to observe and analyze the density of cloth fiber and warp and weft

9. Used in electronic industry, can observe the wiring stripes and quality of PCB copper platinum board.

10, for agriculture, forestry, food, and other sectors of the bacteria, insect observation and research.

11. It can also be used for animal and plant specimens

[precautions]

1. Do not overadjust the focusing gear.

2. Do not fall from height to avoid severe impact.
