PH calibration using Ph 4 buffer

I own a amazonic aquarium (yes.. fresh water). With the RA+ I used to calibrate the PH using ph7 and ph4 buffer, since the aquarium has acid water (about 6.5).

How can I do the same with RA*? The Menu does not give me any option besides Ph7 and PH10.

Best regards
Rafa

You have to edit the libraries and use the Arduino IDE.

Just to register, I calibrated using ph7 and ph10 buffers and after that I tested measuring ph4 buffer and worked Just Fine!!!

No need for any library edition....
