edit screens. When a secondary parameter is changed the g level value will change as a result. See section
4.2.2for details.

Default profile
The default profile is loaded for convenience when the simulator is turned ON. The default profile
contains pre-set simulation parameters which cannot be permanently overwritten. All of the
parameters can be adjusted at the time (on the fly), but
not saved
. The default profile primary
parameters are:
•
Frequency = 100Hz
•
Sensitivity = 10.0000 (mV or pC)
•
g level = 10.0000
•
Type: Sinusoidal
3.4.2.
User profile
The user can create a profile which contains specific simulation parameters, i.e. the parameters
are adjusted to meet the requirements of a particular test. A maximum of 40 profiles can be stored
within the simulator, each with a unique identification. Unlike the default profile, a user profile can
be edited and
saved
on the fly. See section 4.3for details on creating a “User profile”. Note:
Downloading a new profile set will erase any user profiles saved within the simulator.

FFT
The simulator features a basic FFT (Fast Fourier Transfer) function. This feature allows users to
identify the fundamental frequency and order of magnitude, of a complex vibration or similar
waveform. The signal is inputted into the simulator using the shared Tach / FCN BNC connector.
The tachometer output function is disabled once FFT mode has been selected.
Users should
