Hi,
I ordered new probes as stated above, I also have the Ph Calibration solution 7.0 and 10.0. I started with the 7.0. I couldn't get it working. After trying a couple of times it calibrated with 7.0. Then when moving to 10.0 solution, the calibration fails.
I connected the ORP probe and no matter how many times I refresh the page it shows 0.
Conductivity is also failing on me. Please help.
Thank you,
vamsi.
I want to give an update, this morning i tried to calibrate the conductivity using the manual configuration. It did say the calibration was successful. But upon placing the probe in the sump, away from the bubbles, the dashboard only shows 25.10. Which is wrong.Originally Posted by VJ79
Please give me some pointers on how to solve this.
The Ph and ORP are also wrong for now.
Thanks,
Vamsi.
Are you certain you have the pH and ORP cables connected to the right ports?

Hi chad,
I will double check this evening. Any pointers to verify which is which ? I have tried to look at the manuals to identify the ports . I did not find any.
That’s on the first page of the Get Started guide.

Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.
Thank you Russ. I will check this evening and keep you posted.
Chad and Russ,
I am so dumb. I have them hooked in the opposite ports. So the Ph and ORP was never right. No excuse for this. I am really sorry for wasting your time. I will re-check the salanity probe calibration.
Thank you,
Vamsi.
Been there, no worries.
Chad
On the salinity, also make sure the packet is the same temp as the tank throughout the whole process. This can make a dramatic difference in the final calibration value.

i' a new-be to the apex ,But i know how things work, so my salt probe has never worked right. it was all ways wa reading high. now it's not working at all. I;v had it less then a month, will they replace the probe?
Yes, but only if it's actually defective. In your case, from the little information you have provided, I would guess that you may just be missing the step of getting the conductivity packet to exactly match the tank temp during calibration. In 99% of cases I hear about in which the conductivity reads high after calibration the user skipped that step, didn't leave it in solution long enough, or allowed the packet to cool to room temp while waiting for the value to settle.

ho,ok. so the cal. soulotion has to m atch temp?
regarding my temp prob. I didnot see anything about temp alcumation\
Yes. Conductivity is incredibly sensitive to temperature in the vicinity of 1.2 ppt error per degree farenheight difference between tank temp and room temp. This is why it is absolutely essential that the packet matches tank temp almost exactly.
