The Equation Viewer screen provides an overview of any equations created, as well
as allowing the user to create new or edit existing equations. Data is inputted as
described below. Before any data is inputted Name will read 'Not set' and will not
appear on the results screen.
Name Pressing this allows the user to input a unique, alphanumeric name
for the equation. The names entered here will be displayed in the
'Equations' combo box on the Equation Builder screen as well the results
screens. Therefore any equation can be easily identified when using it in
other equations.
Equation Pressing this takes the user to the 'Equation Builder' (see below). Any
equation constructed in the Equation Builder will be displayed in this
box.
Units Pressing this allows the user to enter units for the result of the equation
using alphanumeric text entry. If this column is left blank no units will be
displayed alongside the result.
Del Pressing this deletes the row and removes the equation.
The Equation Builder allows the user to create any equations required in the
method. Data is inputted as described below. To allow data to be inserted or
deleted the cursor can be moved left and right using the left and right arrows. Data
can be deleted using the delete icon and thresholds added using the thresholds
icon (see below).
Variables Pressing on this displays a list that contains any variables added to
the 'Variables' table by the user. Selecting the desired variable enters it
into the equation.
Constants Pressing on this displays a list that contains any constants added to
the 'Constants' table by the user. Selecting the desired constant enters
it into the equation.
Equations Pressing on this displays a list that contains any equations that have
been created in this method. Selecting the desired equation enters it
into the equation.
Sample Data Pressing on this displays a list that contains all of the readings
specified by the user in the Sample Measurement table. Selecting the
desired sample data enters it into the equation.
Symbols Pressing on this displays a list containing mathematical symbols and
the logic gates AND and OR. Selecting the desired symbol enters it into
the equation.
Numbers Pressing this produces the number entry box that allows the user to
directly input numbers into the equation.
Note: All of the data above appears in the lists as it was inputted in the appropriate
table.
After the equation has been inputted the user has two options. If the result is to be
viewed as a number, press the back arrow to return to the Equation Viewer screen.
If the result is to be viewed with a user specified pass/fail limit press the 'Thresholds'
button to set appropriate thresholds for the measurement.
