Elikliv 7" LCD 1200x Digital Microscope: Introduction, Demonstration, Review

****See important information at the end of this Description**** In this video, I introduce, demonstrate and review the Elikliv 7" LCD 1200x Digital Microscope. This same basic microscope is also sold under a variety of other brand names, often in slightly different bundles with accessories, firmware revisions, etc. I hope that most of what I cover in this video is also applicable to those other versions. You can download my enhanced, detailed manual for this digital microscope here: https://www.serpentwebsite.com/filesh... UPDATE 2-26-22 The Amazon listing for this microscope, and the “Instruction Manual” included with the microscope, both specify the magnification as 50x minimum and 1200x maximum, a ratio of roughly 24. By contrast, the “Instruction Manual” specifications page gives the ‘magnification’ as “500/1000”, a ratio of 2; a big difference between this and 24! The author of this video has done empirical evaluation of the actual magnification. A thin metal ruler with 1mm graduations was placed on the Base and the microscope’s “transparent lens protector” was lowered until it touched the ruler, then the focus wheel was adjusted for a clear image on the LCD screen. A distance of approximately 2.14mm on the ruler was magnified to take up the entire width of the screen. Then the microscope was raised on its stand as high as it would go, and the image was focused once more. Now a distance of approximately 14.5mm was magnified to take up the entire width of the screen. This gives a ratio of about 6.8, again quite different from the ratios of 24 and 2 given in the “Instruction Manual”. Based on these measurements, the microscope’s maximum magnification, subject-to-screen (the screen is 153mm wide), is 153/2.14 = 71.5x, and the minimum magnification is 153/14.5 = 10.5x ….. ****** so the magnification specification SHOULD BE 10.5x ~ 71.5x !!!!!!!!!!!!! ****** If anyone can find fault with my empirical analysis of this microscope's actual magnification, or can defend the published 50x ~ 1200x numbers, please enlighten me in the comments below.
