Mastech MS8218 data logging
I used the logging function for real for the first time last week. It works well, although the software has now started to crash occasionally under XP. The crash is not a big deal, because it only occurs when you begin logging. In other words, if it starts logging, it's fine. If not, you know before you lose any data. This would be a total pill if you were waiting for an event before you started logging, because it might crash as soon as you press "Start". But you could always start logging ahead of the event. The only other problem is that the software does run out of buffer at about 45 hours, max. If you want to do weeks of logging - like I did - you have to save and reset the buffer every 2 days tops or lose data. Oddly enough, what little I have found on the MS8226T meter indicates it does not have this problem. It still has the RS-232/USB interface - same style as the MS8218.
