If Grobo Support asks you to do a health check, this is a check that happens prior to calibration of your pH probe.
- By going to your Grobo App > Maintenance > Calibrate, you will begin by preforming a health check
- The health check takes place in 7.0 solution and compares the reading the probe is taking to the 7.0 we know the solution sits at
- If it is not accurate, it will push you to do a full calibration. This will require 4.0 solution, 7.0 solution and tap water
- If the reading is accurate, it will tell you your probe is healthy and no calibration is needed!
