Calibration point Determination 

The showed calibration value 

One point 

calibration 

Asy 

Zero point (Asy, offset or Zero point)= Asy   

1.If not calibrated, Slope = Theoretical slope     

2.If calibrated, Slope = Slope of last calibration 

Two or three 

point calibration 

Asy         

Slope 

Zero point (Asy, offset or Zero point)= Asy   

Slope = Slope

*

 

Note: To obtain a new zero point(Asy) and Slope 

by applying linear regression.
