My Tank Thread
Hi there! So I have a question. I scooped up a DA ph probe and I'm having a little issue understanding the instructions. So it goes as follows
1. Soak ph probe in RO water for 1 hour
2. Go go the first calibration point and soak the probe in the calibration solution for a minimum of 1 hour.
3. Check the raw data for 1 minute.
4. If the number is still changing (1-2 points is ok) let the probe soak for another 15 minutes.
5. Check raw data for 1 minute. If the number is still changing (1 -2 points is ok) , repeat step 4.
6. Rinse in RO water (this is the step that confuses me)
7. Once raw data is stable, save and repeat steps 2 through 6 with the next solution and save.
So I guess the part that really confuses me is it doesnt say anywhere when you go into the calibration to change the value to the calibration solution. And the other thing is that after the raw data is stable it wants you to rinse the probe in ro water and then save and repeat. Wouldn't rinsing it in ro water before saving throw off the calibration??
Thanks in advance for any help and any advice.
