I got my TF-100 a couple days ago and I'm a little confused by the CH test.
Can someone tell me definitively when it ends?
I have the speedstir and I count out 10 drops of R-0012 and see blue. I think it's over and my reading is 200 CH.
If I let the speedstir keep going about 30 seconds later it turns back to pink. One more drop and back to blue. wait 30 seconds, back to pink, one more drop, back to blue. And the process repeats for several more drops. Over the past couple days I've gotten CH readings anywhere from 200 to 425 and I'm not sure what to believe.
Do I keep going until it never turns back to pink, or am I done with that first color change at 10 drops?
Thanks for the help.
