Peak Curve Fit

6.

  Continuing on from step 5, press the 

PEAK CURVE FIT

 soft key. 

7.

  To peak curve fit Trace A press the 

G=PKCVFIT A

 soft key, to peak curve fit  

Trace B press 

G=PKCVFIT B

, and to peak curve fit Trace G, press 

G=PKCVFIT C

.

 

Step 8 and thereafter are the same as for curve fitting.

     Example of the screen for running peak curve fitting when the curve fitting function 

is set to GAUSS.
