Measurement Mode
The Measurement Mode is an active data-collecting mode, which, for that reason, requires the
use of data acquisition hardware. The Measurement Mode can only be selected if a ZonicBook
or WaveBook is available.
The Measurement Mode acquires data using one of the following three methods: (1) Scope-
Continuous, (2) Scope-Single, and (3) Record.
The Scope-Continuous and Scope-Single methods display data, but do not log data. The
scope methods are useful for signal validation and checkout. The Record method, in addition
to displaying data, logs data-to-disk based on user-defined start and stop criteria.
In addition to being selected from the Task Menu, the Measurement Mode can be selected
from the Task Tool Bar by clicking the <Change Task Mode> button while in the Playback
Mode. Clicking this button from Measurement Mode will change the task mode tool bar to
Playback.
Measurement Mode Task Bar
Note that grayed-out buttons indicate that the associated function is not available due to a
prerequisite not being met.
Change Task Mode Changes the task from Measurement Mode to Playback Mode.
The Task Bar buttons will change accordingly.
Record Starts recording data-to-disk in continuous time. Note that a ZonicBook or
WaveBook must be used to acquire data.
Scope-Continuous Starts a block-time data acquisition. This scope method is typically used to
acquire impact data or to take measurements when data storage is not required.
Scope-Single Starts a single-time run data acquisition. This scope method is typically used
to acquire impact data or to take measurements when data storage is not
required.
Signal Generator

the Generator
is turned ON
Indicates that
the Generator
is turned OFF
The Signal Generator button toggles between two images and is only active when
hardware is present.
The sign wave button indicates that the generator is ON. Clicking on it will turn
the generator OFF and the button image will change to a circled red line,
indicating that the generator is OFF.
Clicking the button, while the “Off Status” image is present, will turn the Signal
Generator back ON, and will change the button to show the sign wave image.
Note: For WaveBook and ZonicBook/618E applications you must set the
applicable output channel (that is to generate the signal) to “Active.” See
Output Channel Setup , in chapter 4.
Cursor Lock An active cursor lock button will have the image of an opened or locked padlock.
When the padlock is locked (closed), cursors in multiple windows will be
synchronized and locked, providing that the windows are of the same time
domain, frequency domain, or have the same octave band data.
An opened padlock image indicates that cursors in multiple windows have
independent cursor movement, i.e., they are unsynchronized.
Export This button exports data, if export conditions are set. For details, see the
section, Export Menu> Function Data Set(s) , in chapter 3.
