The factory default settings for the second signal produce a 1-2V signal, where 1V corresponds to an A/F of 10:1 and 2V corresponds to an A/F of 20:1. This signal is designed to be used with a digital volt meter, allowing one to directly read A/F from the DVM's display.
Was this taken off of the site somewhere? There is almost no data on the unit there that I could find, but this would be excellent information (that somehow I missed before). Now the trouble would be finding one that is suitable... 3.5 digit, LED meter, direct voltage readout from input...
