Hi guys

I just bought this pacific Sun kore 7´th kh lab doser 2 weeks ago.

I´m having some serious challenges tuning in the KH lab.

Every measurement i do, the result is not correct!

Every second time, the Dkh is 7 and every other time it is 10.
It is consistent..... 7 - 10 - 7 - 10 - 7 - 10 etc. It is very strange and makes no sense to me.

My water is about 7.7 - 8.0 Dkh.

I have uploaded new software for the computer and the newest firmware for the doser.
Pump 1, 2 and 3 has been thoroughly cleaned and calibrated a dosen times. It still not works correctly. The nr. 1 pump has also been replaced with a new one.

Another problem is that the program i use on my computer does not save the data i enter.
I mean the calibration number etc.
Every time I close and restart the program, alle the data has been set back to default.
So every time i start the programme, I have to enter it in manually.

I have been in contact with pacific sun, but they don´t seem to have the time to help me.
The tech support is apparently on vacation and is only back again in a week or so.

I was hoping that anyone on this forum could help me?
