Temperature calibration

[Gael]

Hello,

I know you say temperature calibration are useless because are done by GHL at factory.
But I have a ProfiLux 3.1T eX with a temp probe and a ExpansionBox with a temp probe.
The 2 probes are for test at the same place and they never show the same temperature…

I write down the original ADC1 & DC2 value for both probes:
Profilux: 604/247
Box: 645/271

And use the lowered/reised with the Adjust temperature tool to set the same temp.

But if they show the same temp at 25° the temp differ at 20° or 30°, that mean this don't work.

The problem is that we can't find the good ADC1 and ADC2 value to set to each sensor because we can't see current ADC value
If we can see current ADC value we can with check water at 20° and at 30° find the good ADC1 and ADC2.

Please can you add the current ADC value somewhere.

Thank

Hello,

GHL, if you do not understand what I have written, let me know please.
English was not my natural language.
I need help :-)

thank you

Hello,

I've replied to your e-mail yesterday.
You have a PM.

Hello,

I received your values. (Sorry your mail was in SPAM, i read it now. Thank.)

These are the original values that I had:-(
But with these values I do not have the same temperature while the two probes are at the same place. I have several degrees difference.

So I repeat my request, can you add somewhere in real-time visualization of the current ADC value in order to find for 20 ° and 30 ° ADC1 DC2 and values in order to recalibrate myself 2 probes.

Please help me.

Thank you in advance

Hello,

Any news?

Thank

[Matthias]

yes, this is already (with a small trick) possible

but how do you want to get exactly 20° and 30°C in a fluid?

Hello,
Thank Matthias to help me,

Can you explain me how to see current ADC value?



but how do you want to get exactly 20° and 30°C in a fluid?
With several other good thermometer already calibrated.

I need a solution :-)

Thank in advance.

If you have a PL with webserver, you can get the raw ADC value of the sensor by calling the following line in browser.


http://<ip_of_your_PL>/communication.php?name=Admin&pass=<pass>&dir=enq&code=10009

Replace the values in the brackets with your ones and ensure the temp sensor is #2 (if not, decrease/increase the 10009 / 1=10008 / 3=10010 etc.)

Hi,

while true; do wget -qO- "http://192.168.1.4/communication.php?name=Admin&pass=<pass>&dir=enq&code=10009" |cat|cut -d'=' -f3;sleep 1;done

And for temp prob on the expansion box:
while true; do wget -qO- "http://192.168.1.4/communication.php?name=Admin&pass=<pass>&dir=enq&code=11001" |cat|cut -d'=' -f3;sleep 1;done
