Yep, even with less lye than normal, a saponifying batter should be definitely alkaline (pH way above than 7). Testing pH in soap is notoriously inaccurate.
"...Does anyone know how it will come out? Will it be safe to use?..."
Honestly? Impossible to tell at this point -- you're asking a lot without sharing your recipe, method, etc. You'll just have to wait until the soap is done saponifying, test for zap (NOT pH), and decide then what to do.
"... Can I transform it into something later?..."
You could rebatch the soap if it's not useable as-is.
Gent made a good suggestion to test your scale for accuracy. I'd certainly do that, but the likelihood of operator error is more likely. We all make mistakes sometimes and it's very easy to blame the equipment when it's really human error.
