The left side of the dialog box shows the calibration information and a calibration
curve. Clicking [-] will zoom out and clicking [+] will zoom in. Clicking [<--] will

The table on the right side shows the concentration, calculated concentration value,
CPS or count, strength ratio (if internal standard correction is used), and detector
mode (P or A) for each level, as well as the RSD table for the element at each
calibration level.
2 To check a point of a level on the calibration curve, perform the following
procedure.
1) Select a line in the table on the right side.
The selected line will be highlighted and a circle will appear around a point on the
graph.
The color of the point on the calibration curve provides an indicator as follows: light
blue for pulse mode and green for analog mode.
