18.4 Creating and setting up a difference calculation
General
A difference calculation gives the difference between the values of two known mea-
surement results.
NOTE
This procedure assumes that you have previously laid out at least two measurement
tools on the screen.
Procedure
Follow this procedure to create and set up a difference calculation:
Push to display the menu system.
1
Use the joystick to go to
(Tools).
2
Push the joystick to display a submenu.3
Use the joystick to select
(Add difference).
4
Push the joystick. This will display a dialog box where you can select the
measurement tools that you want to use in the difference calculation.
5
Push the joystick. The result of the difference calculation is now displayed
in the result table.
