ORP question or a problem..
Re: ORP question or a problem..
Ok, now I've tried everything, and I can say that there is a problem...
1) i've tried adding code that you suggested. It worked only for couple of hours. After that ORP keeps showing 0 mv
2) I've bought expensive Hanna 470 mv solution. Calibrated: as 0 mv it showed numbers 1866, and for 470 mv it showed 188. So for 3-4 hours it was ok, but in the morning I've checked ORP and it is 0 mv again...
I don't know what to do now... Maybe the probe is faulty?

Re: ORP question or a problem..
The numbers you got look correct.
When it shows 0mV, what happens when you reboot RA?

Re: ORP question or a problem..
After reboot it shows the same 0 mv. On controller it sometimes looks that it shows 0.9 or 0.5 (but the last number is cut off)rimai wrote:The numbers you got look correct.

Re: ORP question or a problem..
Use the joystick and go into calibration mode.
What number do you see?
Make sure to choose cancel when you are done. Don't click ok.

Re: ORP question or a problem..
I see 0 mv and number - 0

ORP Extension is connected to expansion hub (all lights are green in ORP extension) tried to change cable from ORP extension to expansion hub - didn't helped.
Re: ORP question or a problem..
What if you connect the ORP module directly into the relay box?
Roberto.
Re: ORP question or a problem..
Ok, tried it. Same result. 0 mv. Connected directly to relay box (main). Also tried to other expansion hub slots. Nothing...
Re: ORP question or a problem..
Can you please go into calibration, connect the terminator and check which values you get?
I want to work with raw values instead of calibrated values, just because there may be a problem with the calibration numbers.

Re: ORP question or a problem..
Getting: 0 mv and 1875 numbers
Re: ORP question or a problem..
Ok, 1875 is good...
So, we know for sure that the module is working and responding with correct numbers.
Can you connect the ORP probe and do the same thing and read what numbers you get one more time just to ease my mind?

Re: ORP question or a problem..
Ok, so can you do the same thing, but using the pH probe now?
Roberto.
Re: ORP question or a problem..
It started to show:
0mv and numbers 100
and keep on going till 1950

Re: ORP question or a problem..
Awesome, that's good because the pH probes give negative mV readings for alkaline water.
Connect the ORP probe back.
Now, what numbers do you get if you place the probe in a cup with tank water?
And what number do you get if you place the probe in a cup with tap water from the faucet?

Re: ORP question or a problem..
In cup with tank water: 0 mv and 0 number
In cup with tap water from the faucet: 0 mv and 0 number

Re: ORP question or a problem..
I don't know what happened. Didn't do anything but suddenly it started to show some ORP values... When calibrating getting:
0 mv and 619 numbers
Same was and other days...After the night it showed again 0

Re: ORP question or a problem..
I don't think so, as everything is connected without tension. And nothing was done or even touched and it started showing somethingrimai wrote:Could it be any bad connection somewhere??
Re: ORP question or a problem..
Ok, let's keep an eye on it.
According to your log, it's been working since yesterday when you mentioned it was.

Re: ORP question or a problem..
Yes let's keep an eye.
Re: ORP question or a problem..
I have same problem again. Tonight as I see by chart it started to show higher values and now I'm getting only 0 mv.
What I've tried:
1) Connect ph probe - readings ok
2) reboot device - nothing
3) turn of orp module - nothing
4) reconnect orp probe few times - nothing
I'm confused now... I need help...

Re: ORP question or a problem..
Maybe its time to replace ORP probe...Because I don't know what else could be..
Re: ORP question or a problem..
Hi I have just installed my ORG module but cannot find where i set it up.
I selected it on the wizard but nothing comes up to set up the parameters.
Please can you help me.

Ok, I got ORP replacement and now it works perfect without interruptionsArmetas wrote:Maybe its time to replace ORP probe...Because I don't know what else could be..
