: I have some questions concerning Pico Log:

Hi Brad,

Paying with PicoLog huh? I have not used that much, just played aroung with it a bit.

: In an automotive application, is there any advantage in using Pico Log over the save to disk option in Pico Scope.

I have not found it terribly useful in automotive. If you find a good use, please post some tips here. You can graph frequency with PicoLog, but only in Realtime Continuous mode. The update for frequency calculation seems rather slow, although you can see dips in the graph when there is a significant change.

In Fast Block you can monitor a voltage over a long period. Naturally the sampling interval is related to the time for the block.

I'm much more accustomed to using PicoScope. If you get comfortable with PicoLog, please teach us.

: Doesn’t Pico Log create it’s own folder and still write to disk?

You can set it to write to the location you choose as well as how it responds at the end of a run (restart immediately, delay, etc)

: Is Pico Log to be used mainly for long time frames, say over 5 or 10 minutes or perhaps to catch that intermittent glitch during a road test of say 30 to 45 minutes?

The more time you put on a run the longer between samples. You can restart the runs with less time on each one and it will write each log to the hard drive. There will be gaps between the logs though. You can run a scroll mode though.

: I see I have the FAST record option in Pico Log, does that include the zoom option for all recorded information as in block mode in Pico Scope ?

You can expand and zoom in on the log graph. The fast block mode works like the block mode in PicoScope. It collects the data then displays it all at once, in a block. You can open the logs with PicoLog player. Just as in PicoScope, turn your samples up to 32,000 for faster sampling.

: If I use Pico Log to record a LOT of information during a long road test, is that information easily deleted when I’m finished with that vehicle, so I can save space on the lap top’s disk ?

Sure. You can delete the files the same as you would any other file.

I am by no means an expert with PicoLog. If you find a really cool use for PicoLog in an automotive application, please share it with us. Play with it and let us know :-)
