For erasing EPROM memory chips, all data in EPROM can be completely erased in 10 minutes. 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. use the programmer to check the chip programming. Note that the chip is placed with the glass window facing upwards. Some manufacturers' chips will take a long time to erase. refer to the chip manufacturer's instructions for details. If the chip is aging, the erasing time will be long or cannot be erased.
