my PS234 reports salt at 2200ppm (11 drops).

That sounds *very* low.
AutoPiiot reports 2900
Leslie's reports 3000 (strip)

I've tested it 3 times... cleaned the tips, etc.

FC+CC, TC, pH, Alk, Cal, CYA matched my HTH 5-way.

Leslie's (day later) matched except for salt (above) and Cal. They showed 125, I got 230 with PS234 and HTH. I think Leslie's is wrong on that.
