Apex probe not calibrating!

[MillerR.]

Ive tried to calibrate the PH probe manually and using auto. I even tried with a different probe with same disappointing results. Any suggestions? This is the newer orange Apex.

Are you sure you have your temperature compensation set correctly?

And did you warm it with the aquarium water

I had it disabled, should inable it and what should it be set to? I did not have this enabled when I first calibrated and it worked fine.

It was room temp. I'll try again with tank water temp.

I haven't used Apex for awhile but if I remember correctly the best way to do it is to float the pH samples in the tank water to match temp, and then set the calibration temperature to match the tank.

Looks like the apex only lets me turn on TC compensation but not set a value, I'm sure I am doing something wrong.

I wish I still had my Apex set up so I could see it again. :confused:

Problem resolved, user error!

 

[CindyKz]

what was your error?

 

[MillerR.]

Don't make me say it! lol

 

[CindyKz]

Ok I won't...but how bad can it be? No judgement here, that's for sure :)

 

[MillerR.]

I'm not confirming nor denying I was calibrating the salinity probe and not my Ph probe. Note to self organize your wires and equipment! Lolol

Lolol....fwiw, I just untangled and labeled all of my cords and wires day before yesterday. $15 labelmaker...priceless!

 

[MillerR.]

The sad news is I labeled the power chords but not the probes!
