1-point Asy  Zero point = Asy
 Slope = Nernst slope
(-59.2 mV/pH at 25 °C)
2-point Asy
Slp.  Zero point = Asy
 Slope = Slp.
3-point to 5-
point Asy
Slp.  Zero point = Asy
 Slope = Slp.
The calibration line is calculated by
linear regression.
You can display the slope in the units, mV/pH or % (see section

The calibration record is automatically transmitted to the interface
after calibrating.
