Question : 

How can I turn on the logger/recording mode on the 700G ? 


The 700G Manometer has a logger/recorder mode.  This can be activated on the 700G itself.
Press Config ->  Log Data is shown. Then press Enter ->  Log off is shown.  Then press up(zero) or down(Min/max) -> Log Start is shown and again press Enter.

The 700G will now show alternating LOG and RUN with a number.   And this is shown as long as the manometer is logging. 

The optional 700G/Track software is required to download a logging from the 700G manometer.
