What file? If you mean the HP Journal then just download it from somewhere else. I would have linked to the file at hpmuseum.net but for the past couple of days it appears to be down.

Yes, the 3421A is simple to use, but it's capabilities are beyond your imagination. Are you familiar with the 3056DL Data Logger System?
