UV EPROM Data Timer Eraser 1. For erasing EPROM memory chips, all data in EPROM can be completely erased in 10 minutes. 2. When using, first remove the light-shielding sticker on the EPROM memory chip window. The eraser can erase up to 6 chips at the same time. Set the timer at 10 minutes and turn on the power. If the erasing is not clean, you can extend the erasing time. 3. Please use the programmer to check the chip before programming. 4. Note that the chip is placed with the glass window facing upwards. Some manufacturers chips will take a long time to erase. Please refer to the chip manufacturers instructions for details. If the chip is aging, the erasing time will be long or cannot be erased. 5. Drawer structure, drawer size (length, width and height): 95X55X13 millimeters (mm) 6. Built-in ultraviolet lamp, the wavelength of the light source is less than 400nM (it can be used for the development of some photosensitive materials or the light curing of small prints). The specific effect is subject to actual use. We cannot promise and guarantee. 6. Novice buyers, please note that as long as the purple light in the drawer can be controlled by your timing and switch, this device will have no problem (the purple light can be seen on the small hole of the drawer after turning on the power switch and the timing switch). If the erasing is not possible or the erasing is not clean, please find other reasons, such as removing the shading paper, cleaning the glass window on the chip, troubleshooting whether the programmer is normal, and confirming whether the IC has been aging and damaged.
