Would you mind directing me to the place where I can properly reply? I see the forum but I don’t know where my question is

Did you get a chance to run that ph test?Ok I will try that tonight
First you want to make sure the meter works. To do this put the black probe in the COM and the red probe in the V which is the hole above the COM. Turn on meter. Select the ACV 200 position. To test the meter first, find an outlet in your home and put the black probe in one of the elongated slots and the red probe in the other elongated slot. The round hole in the outlet is the ground and is not used for this measurement. Depending on your electrical service the meter should read 110-120VAC.No I didn’t, I had to mow…in the dark lol…and it’s in the 40s ha
I’m trying to figure out my multimeter as we speak.
Thanks for checking in. Any ideas on how to work this thing?
When you say slowly are you talking within a minute or two or is it longer? Probe should stabilize within a minute. At least my GHL probe does. Previously did the PH drop when you turned the pump off or when you turned the pump back on? Is it a fast change or slow over many minutes or hours? Could you do a screen shot of your ph chart during the time frame of the issue you were seeing? If your not sure how to do that I can help with that.Ok I did the test and with the 9.0 fluid my probe read 9.03, which I can live with. I placed the probe back in the sump in a high flow area after my skimmer and the reading immediately dropped to 7.85 or so and slowly came back up. It’s currently at 8.31/.32. I’m gonna give it overnight to see where it stops as it may still count up to well above 8.3. If it’s still there in the AM I will turn the pump off and see what happens. Although I do know that is what usually makes it read incorrectly.
If I’m working my multimeter correctly, no stray voltage noted. 0.00
Downward spikes could be caused by the collection of micro bubbles, then when to much air is collected on the tip of the probe a big bubble will release and the ph reading will go back up. I have seen this with the conductivity probe in the past but honestly not so much with the ph probe.Ok a couple of screen shots from overnight. The period where pH was around 8.3 was right after I calibrated. You can see the slow drift up over a few hours. And then of course the drop likely to coincide with the skimmer issue. Otherwise I’m confident it would have kept rising because that’s what it does, and it sits at 9.xx
No because that is a "Do not reply" email as mentioned in the email itself.So when your response to the ticket comes to my email, and I respond on that same email thread, you don't see it?
The point is that this is a new probe and it never operated properly.I would try another probe. It’s good to have several if you are just using these cheap hobby grade probes, Reliable lab grade probes are spendy and they still go bad too.
i thought the point was to have it functioning correctly. Get a second probe and if it works you prove you’re correct And your new probe is faulty, congratsThe point is that this is a new probe and it never operated properly.
