Not a problem

You're unit won't tell you the pH.

To change between ppm and gpl all you have to do is hit the diagnostic button once (which shows you temp) and then push the switch from "AUTO" to "SUPERCHLORINATE" and back down to "AUTO" - who says there are no easy answers?

As a side note, while it's nice to know the 'real' salinity of the water, the unit will only produce chlorine if it 'thinks' the salinity is within the correct range, so save the strips and the tester for when the unit is 'balking' and you know that there's enough salt in the pool
