I just bought a used Spectroline PE-240T. I did not get any instructions. Can't seem to find any information on the internet. Seems like its a discontinued model.How do I use this? How long do I leave them in.....ect....
2-5 minutes is usually plenty, then blank check. If not blank put them back in for a minute or two. Repeat until they are all blank. Some of the larger chips like 27c010 and bigger can take alot longer to erase but I still check them after 4-5 minutes.
It will also depend on the size of the erasers bulb and the condition of the unit.
