Ph metering issues

[Seagals]

Hi Roberto,

I recieved the ph cable extension and finally got around to calibrating the probe and getting the probe into the tank but I am having some issues and was wondering if i did something wrong. I followed the steps as far as RO water, 7 and 10 calibration solution and using the calibration menu on the controller. The problem is the meter started out reading erratically, than read 6.2 steady for a day or so and yesterday and today its reading 1.03 steady.

The number on the controller when i did the calibratons were as follows:
for ph 7: 554
for ph 10: 828

I took the probe out and put in a glass full of tank water for about 2 hours and it still reads 1.03 steady since. I also checked the connections and made sure the ph cable was at least 6 inches away from all other electrical wiring.

Any advice??


Thanks in advance

Those numbers sure looks correct.
If you go through calibration again, do the numbers look similar?

Pretty much the numbers the first time was
ph 7 : 546
ph 10: 821

[rimai]

Those numbers are good.
What ph value do you get if you finish the calibration and place the probe in the solutions?

[Seagals]

In 7 she is @ and 10 @ 8.12

Something is not adding up here.
Can you use this code:

Code: Select all

void setup()
{
  ReefAngel.Init();  
}

void loop()
{
  ReefAngel.LCD.DrawText(0,255,10,10,ReefAngel.PHMin);
  ReefAngel.LCD.DrawText(0,255,10,20,ReefAngel.PHMax);
  ReefAngel.LCD.DrawText(0,255,10,30,ReefAngel.Params.PH);
  ReefAngel.LCD.DrawText(0,255,10,40,analogRead(PHPin));
  ReefAngel.Refresh();
}

Post the numbers you see when you place the probe into solution 7 and solution 10.

Copy and paste in a new sketch.
Use that code as is.

[Seagals]

ha? delete all my current codes and replace with this - temporrily??

[rimai]

yes. upload that code, run the tests and upload your code again.

[Seagals]

552
829
645
501

[rimai]

In which solution was it in?

[Seagals]

It was in a cup of tank water that measures at 8.4 with tests - i did not know it needed to be in a solution, does it?

[rimai]

Yes, I'm trying to find out what it going on with the numbers.
They don't add up.
You are saying that you place in solution 10, it reads 829 and yet when you place in the same solution a minute later, it doesn't read 829 anymore. 829=pH10.

[rimai]

Post the numbers you see when you place the probe into solution 7 and solution 10.

[Seagals]

ok, we are having a communication breakdown. when i put the probe in the solution a few hours ago it was without running a test, i dod not know we were testing it in a solution. Are we just testing it in one solution and runniing a test or are we running 2 test one for each solution?

I want to make sure we are clear on what troubleshooting i need to do on my end.

Is it 1 test for 7 in 7 solution or is it 2 tests 1 for 7 solution and 1 for 10 solution?

[rimai]

2 tests.
One for each solution.
Load the code
Place the probe on solution 7 and post the numbers
Rinse
Place the probe on solution 10 and post the numbers

And just to confirm, you are not returning the probe to the storage bottle, correct?
You discarded it already, right?

[Seagals]

Yes storage bottle is discarded - Thanks for help but i will need to get back to you tomorrow on this i am not feeling well. thanks

[Seagals]

Ok

the test had same results with 7 and 10 soultion
552
829
103
0

[rimai]

That doesn't make sense.
The 4th number is the same number you get when doing calibration and it's zero right now.
Can you go into calibration mode again and see what numbers you get?

[Seagals]

I am sorry i am not understanding when you say calibration mode do you mean upload code again or do you want me to go to calibration thru the controller, if so, in which solution?

Currently, the probe is in the tank and if i go into the controller and select calibrate both ph7 and 10 are at 0

[rimai]

Yes, that's what I was asking you in the beginning of the thread. When you go into calibration mode with your code, you kept saying it is reporting the same numbers.
550 and 830, right?
Those numbers are the same exact reading as the 4th line of the test code I sent you.
No matter which code, the calibration mode and the 4th line of the test code are the same raw reading from the controller.
What I'm not getting is how you get 550 and 830 with one code and 0 with the other code.
They should be the exact same thing.
The 1st and 2nd line of the test code are the numbers stored in the memory from when you initially done the calibration and they are correct. The 3rd line is the interpolation of the 4th line and those numbers to convert it to pH values.
So, if the numbers are showing 0, that's different from when we started the thread right?
Twice you posted you were getting the numbers you posted.
So, just to confirm, something has changed now, correct?

[Seagals]

I am not sure what changed the controller itself outside of the calibration mode still reads 1.03 as it did yesterrday.

[rimai]

No, not outside calibration. I'm talking about when doing the calibration.
Let's start over again.
Load you code
Enter calibration mode.
What are the numbers you see when placing the probe on pH7 and pH10 solution?

[Seagals]

When i load the test code the entre tank shuts down and the controller reads
552
829
103
0
and is locked - i press the joystick and nothing happens it just show the series of ##.

[rimai]

We are starting over.
Please do the following:
Load your code
Enter calibration mode.
What are the numbers you see when placing the probe on pH7 and pH10 solution?

[Seagals]

both 7 and 10 state '0'

[rimai]

Ok, that's what I wanted to confirm with you.
In the beginning of this thread, you stated twice that the numbers were 550 and 830.
That's why it didn't make sense.
The numbers have changed to 0 since then, correct?

[Seagals]

no

[rimai]

no

Huh??
What do you mean?
