specific table. To use a variable in more than one data acquisition activity table, you must map it for each
table.
8. To select the data acquisition activity table that you want to work with, click the down-arrow in the Select
a Data Acquisition Activity box and select the name of an activity table.
9. To map a signal to a variable:
a) Select the signal name in the Signal to Variable Mapping panel.
The Signal to Variable Mapping panel provides information from the test run. The items in the Variable
column are available in your test and contain test data values.
b) Click the down-arrow in the Variable column and select the variable name or <new variable>.
c) If you select <new variable>, a window opens so that you can define a new variable. Complete the
boxes as necessary and click OK.
The Additional Variables to Calculate panel provides information about other calculated values contained
in your analysis definition. The items in the right-hand frame are designated for recalculation at the
end of every cycle.
10. To calculate a variable for every cycle, select the variable name from the Additional Variable Calculations
list and click the right arrow button.
11. When you have finished the mapping, click the Refresh button.
The recalculated values are updated in the analysis run you currently have open.
A recommended procedure is to create a copy of your test and analysis definition.
12. Click File > Save As to save your test.
13. Type a new test name and click Save.
The variable definitions and mapping are transferred to your new test and can be modified to meet your
requirements. Your original test is protected from any new values, variables, and calculations you make
in your analysis. The test data does not change. Analysis data and calculation changes do not modify the
test run data in any way.
With the variables defined, mapped, or calculated, you can begin reviewing and analyzing the data through
the various charts and tables.
6.2.0 Variable Table Analysis
The Variable table enables you to directly change data values in the Value column. When you refresh the
analysis run, you can examine the effects on other values. The altered values are an overlay of actual values,
and no test data is changed. Additionally, you can map measured signal data to variables and override their
values.
6.2.1.0 Changing the Value of a Variable
To change the value of a variable in the Variable table:
1. Click in the table cell that you want to change in the Value column.
