Input Configuration
Setting Sensitivities for Inputs
The inputs must be
configured for each
connected accelerometer.
Each input can be
configured as single ended,
differential, and optionally
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 VR9500 to provide the constant
current source to your accel.
System Limits
Shaker Limits and Moving Mass
The controller checks the system specifications to determine if the
shaker is able to perform the current test. 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.
