I emailed the sellers with a few questions so hopefully i get some replies soon. maybe i need some of that powdered 6.89 instead of the liquid. i cant even get a 7 calibration now, and i need to test some water for feedings since my girls are in 12/12. AHHHH what to do what to do.

time for a smoke break and think things through
Did you get the same meter? Or did you get a digital one?
In order to properly calibrate a pen you must keep it in the solution (first time) for 2 hours. Then adjust with the mini screw driver. Is your adjustable?
