Help my RKL reads 4.66 pH !!!

[PR_Reefers]

Okay besides the fungia incident, for those of you that saw my previous thread, yesterday I found my RKL registering 5.0 pH and lows of 4.66!! Sps looked fine so obviously I knew it was a RK error, plus I top off with kalk. I proceeded to cleaning the probe with vinager solution and afterwards seemed to read normal ph of around 8.1.... however today it read 4.x again!

Anyone experienced similar problem before? Should I just recalibrate it or could it be a module malfunction, etc? it's fairly new so it's still under warranty. Any advice is appreciated thanks!

Recalibrate it. If that don't work, warranty it.

it only has around 3 months I calibrated it the first time never recalibrated it. How long did yours last? do you know if they're covered by the warranty?

Recalibrate it. If that don't work, warranty it.

I will however I need to purchase the solutions... I have the ones I used previously maybe I'll use those to see if it's working first anyways...

Do you fully submerge the probe? or leave the top of it out of the water?

I leave more 1/4 of it out of the water? I assumed the cable or top part shouldn't get wet, right?

Cleaning with diluted vinegar & recalibration worked for me in case anyone has similar problems hope I don't have to do this every 2 months...
