5.4.1 MEASUREMENTS MENU
The initial screen that the DLTM4 comes to is the Measurements Menu. The Measurements menu is depicted in Figure 8.
The Measurements Display provides status of the currently running test. The Clear (F5) button clears out any current
measurements and allows the test to continue running. The action field is associated with the send button. The action field
allows the user to select between different actions to perform during a test. The table bellows describes the actions.
