Agilent 7500 ICP-MS ChemStation Operator’s Manual
Tuning
Clicking on a parameter will cause a text box or a scroll bar to appear at the lower
center section of the window. Use one of the following methods to set a parameter
value.
• Enter a new parameter value in the text box (next to the parameter you want to
change or above the scroll bar).
• Click the right or left arrow at the end of the scroll bar (a), which changes the
parameter value by small increments.
• Click the scroll bar (b), which changes the parameter value by larger increments.
• Click Apply to set the adjusted parameter value.
Clicking Cancel will cause the pre-adjustment parameter value (value stored in
the tune file) to be set.
Adjust the tuning parameters until the signal appears constant and the numerical
values meet performance requirements. The performance specification depends on
the application.
For the workings of each tuning parameter, refer to “Each Parameter's Function” on
page 4-66.
CAUTION Use care when adjusting values by clicking the scroll bar or entering a new value in
the box above the scroll bar. Changing parameter values too quickly can cause
extreme changes in the Agilent 7500 and can alter its performance over time. In most
cases, you should adjust the tuning parameters by clicking the arrows at the end of
the scroll bar.
NOTE To display all the tuning parameters, check Advanced Setting to ON.
13 Click Stop to stop the display.
ChemStation freezes the real-time display until you click Start. When you click
Start, the display clears and starts again.
