This option allows you to add new formula definitions (up to a maximum of 40), and edit or delete existing
definitions. You can use up to 16 variables pre-defined by the instrument and 2 user defined numerical
variables that are set up manually at the end of each measurement.
When the option is selected a screen will be displayed listing all existing formulae.

Press the
New
button to create a new formula. The formula editor screen is displayed (see
Figure 5 below) and used to define the formula. The measurement values that can be used
are listed down the left side of the screen and are defined as listed in Table 1 on page 37 .
The operators and operands are listed down the top right. In the bottom right of the screen
are a number of screen navigation options to assist in editing.
The colored indicator in the top right corner shows the validity of the formula as it is being
created. It is initially colored yellow but will turn red if the formula is invalid and green when
valid. When the indicator is red, the

button will be unavailable.
Use the
Select
button to select an existing formula to include in the new formula. The list of
existing formulae is displayed as a rolling list.
When a valid formula has been entered, press the
Ok
button to continue. You are then
requested to assign a name to the new formula, after which an information box is displayed
showing the name of the user who created the formula and the date and time it was created.
If required, add any free format alphanumeric text to identify the formula and press
Ok
to
continue.

screen is displayed to allow you to change the definition of the formula.
