Coupling AC or DC coupling can be set on an individual channel basis from the Input
Channels tab. Coupling is available for analog channels (CH1 through CH8) and
for compatible expansion channels [e.g., from a WBK18]. AC Coupling can be set
to a high pass filter value of 0.1 Hz or 1 Hz. The value is selected in the Edit
Menu’s Analyzer Tab (see page 4-5). Note that when DC Coupling is selected the
high pass filter is bypassed.
When the Coupling function is not available to a channel, or not used by a
channel, a dash appears in that channel’s Coupling column.
EU Mode E(ngineering) U(nits): Select EU or Volt.
Reference Note: Gain and offset adjustments are made from the Calibration
window. You can access the Calibration window from the Task Menu when in
Measurement Mode, or from the Input Channels tab. The following parameters
apply:
• mV/EU to set the scaling factor of millivolts to Engineering Units.
• EU Offset to set the offset factor that is to be applied to the Engineering
Units.
• dB EU Ref: is applied to displayed data when the Y-axis scale is set to
dB. This is valid only for frequency domain data.
Units Enter the measurement units you will be using.
Location This is a simple numbering system. The channel number is the default value for
location. However, you can highlight a cell and type a different location number.
When you press the Enter key, the value is accepted.
Coord This is the axial direction of the transducer connected to the channel. Make your
selection on the popup menu that appears after clicking in the applicable cell.
Input
Type
This is the type of instrument attached to the channel. Menu
selections include: Acceleration, Velocity, Displacement, Force,
Pressure, Stress, Strain, General, and Tach (Tachometer).
Input Type refers to the Analog Input channel type for CH1
through CH8.
Note: Tachometer properties for the eight Analog Input
channels (CH1 through CH8) are set in the FFT Setup
tab. Refer to that section of the document for additional
information.
ZonicBook/618E users - do not confuse an analog input channel (CH1
through CH8) with a TACH Channel input (T1, T2, T3, or T4). The later
is discussed in the following section.
