Hello all smart people of this community,

A newbe here. A couple of days I received my RA+ and got it to work. Created a few rules with the wizard and so far it works as planned.

However, as a little kid, I started to press buttons here and there and I messed up my ph calibration settings. My probe reads now 3.27, which is of course way off.

I read somewhere that the ph probe comes calibrated by default, which would be quite accurate.

So my question is: 'how do I get those settings back?"

Please help.

Thank you in advance.

Run the memory initialization pde again that should reset the default value and i would not say that it is accurate...maybe more so than 3.27

Dear Lee,

Thank you for your quick response, much appreciated.

It worked, reading is now 7.65, a bit low as my tank should be 8.2.

May I ask you another question?

I've read that people make their own calibration fluid with Borax, which gives a 9.2 value. In order to calibrate, do you need two solutions or can you calibrate with one only. If so, how should one do that?

Thanks.

Leslie

You need two values for the calibration. That's why 7 and 10 are recommended values. Theoretically the 9.2 could be used, but you'd still need a low threshold to compare to.
