Input Configuration
Setting Sensitivities for Inputs
The inputs must be
configured for each
connected accelerometer.
Each input can be
configured as single ended
or differential and, optionally,
as capacitor coupled.
Single ended inputs can
also provide a constant
current source to power
your accelerometers. Other
types of accelerometers
such as charge coupled
accelerometers require external conditioning. Be sure to enter the proper
conditioner calibration factor in the Advanced Settings option from the
Inputs tab.
To view/edit more information on an accel, click the Advanced Settings
button. If the connected accelerometer has TEDS (Transducer Electronic
Data Sheet) containing the calibration information, simply click the TEDS
checkbox and the information will automatically be entered when you
click Read All TEDS . When the appropriate values are entered, click
the OK button. The new accelerometer sensitivity factors will take effect
immediately.
Note: Be sure to check the Accel Power box if you want the I/O unit to provide the constant
current source to your accel.
System Limits
Shaker Limits and Moving Mass
Before every test, the I/O unit checks the system specifications to
determine if it can be performed within system limits. The shaker force,
velocity, and displacement limit values only need to be entered once when
the system is first configured. The fixture and product masses that are
required to properly compute the acceleration limits of the shaker must be
entered every time the fixture or product mass is changed.
