So my apera ph60 needs calibration every time I use it. Only about a year old and I'm getting wild readings all over the place. Bought a new probe for it and it's still doing the same thing. Put the new probe on yesterday, soaked it and recalibrated everything and this morning it's reading 7.26/3.86/10.88 with the 7.0/4.0/10.0 solutions. I've emailed them for support but no response. Anybody know if there's a reset or way to fix it? It's basically killing all my plants
