Correct. You need solutions at those levels. As sovreign said, they're typically available at levels around 4, 7, and 10.
With the example code, you'd insert into the buffer solution, then run (for example, in Python)
```
# place in buffer of nominal ph of 10
V1, T1 = sensor.calibrate(CalSlot.ONE, 10, OnBoard())
# place in buffer of nominal ph of 7
V2, T2 = sensor.calibrate(CalSlot.TWO, 7, OnBoard())
Then save V1, T1, and the buffers you used to a file, your database etc. Or just write them to your `py file.` The MyCodo version, for example, handles that automatically.
Then next time you run, load
sensor.calibrate_all(
CalPt(0.,7., 23),
CalPt(-0.17, 10., 23)
)
If you just edited the file. Or those values would be loaded from a db.
