Square clip on magnifying glass

Overview
FDJ-G seriesclip-onmagnifying glassThe structure adopts a special sturdy articulated arm design, which is easy to adjust and use. The light is stable and reliable, with no flicker and no impact on vision. The circuit uses the latest ballast circuit from the United States, with a power factor of over 0.93 and a current distortion of less than 40%, fully complying with IEE national standards. It is recommended to use square lenses with a wide range of 177 * 113mm for long-term observation. The surrounding deformation is much smaller than that of circular lenses with a range of 127mm, making long-term observation more comfortable. White glass not only has high optical clarity, but also provides a more comfortable viewing experience compared to green glass (ordinary glass), reducing visual fatigue caused by prolonged use. There are different multiples to choose from.
Purpose:
Widely used for printing quality control, observation of printing dots and angle sizes, printing color separation, silk screen mesh measurement, color printing and overprinting error measurement, as well as fine identification, assembly operations, pipe and metal section observation, it is an essential tool for the printing industry and circuit board inspection, precision electronic components, antiques, jewelry, jade and other identification. It is also suitable for philatelists, medical clinics, beauty salons, readers, hobbyists, engineers, and other groups of people The desk lamp style magnifying glass is particularly suitable for households.

Precautions
Please pay attention to whether the power supply voltage matches the actual voltage before using the product.
When changing the direction and position of the magnifying glass, if the locking button of the adjusting arm is too tight, please loosen it slightly and tighten it after adjusting the position and direction. Never forcefully pull to avoid damaging the components.
The magnifying glass series adopts a preheating start method. After turning on the power switch, preheat the lamp tube for about 1.5 seconds, and then the lamp will light up normally.
The magnifying glass series is equipped with abnormal state protection. When there is an abnormal phenomenon in the lamp tube (open circuit, failure to start, leakage), the electronic circuit will automatically shut down and remain locked until the power is turned off to eliminate the abnormal phenomenon.
When the lamp does not light up, check if it is caused by aging after long-term use, and if so, replace the lamp. If the light does not light up after replacing the lamp tube, please check whether the lamp tube (22W lamp tube filament impedance is 5 Ω, 12W lamp tube filament impedance is 10 Ω, 7W lamp tube filament impedance is 11 Ω), lamp tube plug, and power plug are properly connected.
