4.7 Recalibration
To calculate the recalibration coefficient, carry out the recalibration analysis.
1 Select Analysis - Recalibration on the menu bar.
2 Input the name of the analytical group in the Group textbox or select it by
pressing S4:Group key.
3 Select the name of the recalibration sample to be analyzed in the Sample combo

Screen 4.3 Recalibration
4 Set the sample on the spark stand and hold it by the sample holder.
5 Start the discharge by pressing 1:Start key or the start button on the spark stand.
6 Take out the sample, and change the position of the sample to be analyzed.
Then, repeat procedures 3 and 4 specified times.
7 Repeat procedures 3 to 6 until the analyses of all the recalibration samples are
completed.
8 Press 3:Cal. Key.
The recalibration coefficients (
α, β and k values) are calculated and they are
automatically stored in the recalibration information.
In the case of one point recalibration, coefficients
α and β are not initialized. In
the case of two-point recalibration, k is initialized to 1.0.
