My KH director, i dont know what happened on it. Everything was ok, after a day, it was wrong, my KH is 7.7 and now it is 0.4 0.5 and 0.6 each check.
Does anyone have the same problem before? I tried to reset my device and do a test with ph 4 and 7, but when i put probe to ph4, the number is still 0.
So is there any problem with it? But it is strange, when i put back the probe, i see in KHDirector , ph still change, 2.8 ~ 3.5.
