Channel Menu: Setting up the parameters of input channels
Channel Setup Menu allows the user to select various parameters related to
each channel.
Channel On/Off selection, Input range, Coupling type, Window type, Force
factor, Exponential factor
Channel ID, Auto Advance, Advance number
Select channel setup to define each channel according to what you are
measuring. You can turn each channel on/off, select the input range,
coupling, window, and other parameters for making a good measurement.
ON/ OFF
: Turns on/off each channel
Input Range
: Select Auto, Up Only, 10 mV, 20 mV, 20 mV, 50 mV, 100 mV,
200 mV, 500 mV, 1V, 2V, 5V, 10V, or 20V. This should match the output of
the device that you are connecting to. Up only is typically used with modal
impact testing where the range will increase “up” as required to locate the
correct input range.
Coupling
: Select AC, DC, IEPE, 200V Mic. or 0V Mic.
Window
: Select Rectangle, Hanning, Flattop, Force, Exponential.
Force Factor
: Enter the desired force input box and then press [
OK
]. The
width of the force window in this case is 0.1 or 10%.
Exponential Factor
: With the [
Navigation
Keypad
] enter the desired value
and then press [
OK
]. The attenuation rate of the exponential window in this
example is equal to 0.1 or 10% at the end of the time block.
