Clearing Adaptive Values

[johnvw]

Hi to All,
Two questions :
I completed my first data logging, all was O/k, after the Forums assistance.

During the trial data logging (getting familiar with the GS), I switched to the visual O2 sensor chart and the six element visual chart ( you can see that I am not quite proficient as yet ), DOES this interrupt the recorded data logging or is it O/K to view charts whilst running the data log.

I am about to install an AF-Xied, but would like to record my current data. To erase or clear the current adaptive values do I just disconnect the +ve battery terminal ( how long for ), or is there another method that will not send my heart into palpitations.
Thank you in advance
Regards
John
ps I did search for this without any luck.
