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 at 10 minutes and turn on the power. If the erasing is not clean, you can extend the erasing time.
