How to distinguish the original electrostatic tester FMX-004 authenticity
1, the shell material is different. The surface of the imitation is rough, the product is very smooth, the original is made of conductive plastic shell, but the shell of the imitation is general plastic, the surface resistance value is larger than 13 square, so the LCD display is unstable, this is available Japan imported ST-4 surface resistance tester for testing.
2, in the electrostatic field measurement mode, the imitation measurement exceeds the accuracy, the difference is about 10% and higher.
3, the sound of the speaker is different. The internal circuit board of the imitation is different from the original Japanese circuit board (removable machine view).
4. In the ion balance measurement mode, the voltage applied directly on the balance board, the displayed reading is unstable.
5, the product is flat, the imitation display shows all the LCD patterns, can not read the measurement as the original.
How to distinguish the original Japanese electrostatic tester FMX-004 authentic appearance difference
1, the test version of the disassembly switch, from this test switch can be seen, the imitation version of the product button is relatively simple, and the original genuine product button in the middle of a small depression, in the hand feel the production process is more sophisticated.
2, the appearance of color, according to the understanding of various imitation products in the market, the imitation version of the color is generally gray, the label is dark yellow; and the original genuine product color is white and bright, relatively new color, not in the hand will give people a kind of " Old feeling.
3, the test version of the disassembly switch has a small recess difference, the grounding wire hole and the middle of the small label are a small difference, the imitation version of the grounding wire hole in the middle is a metal jack, and genuine original is the same color with the same material jack. Mark the digital product small label, the imitation version has Japanese Chinese character labeling; and the genuine original is a solid color small circle label, there is no so-called Japanese kanji labeling.
4, standard accessories grounding wire: the original original line is obviously much thicker than the imitation version of the line; the grounding wire clamp head genuine original rubber technology is delicate and smooth; the imitation version is rough, not slippery, and the material is hard.
5, the product internal desiccant, the original original desiccant is non-woven material, the packaging is neat; while the imitation version of the desiccant is ordinary paper, the permeability is not good, the packaging is prone to creases.
6, the product is original Japanese original, including the verification certificate. (Some of the imitation goods also have a verification certificate, but the paper is rough, the font is fuzzy,)
