The Spectra Graph
The Spectra Graph provides a powerful tool to determine if the installation has achieved an
adequate margin of operation. It also eliminates the possible effects of mechanical vibration
and external RFI (Radio Frequency Interference). Mechanical vibration and external RFI can
cause other types of Doppler flow meters to be inaccurate. The Spectra Graph display
provides keypad control keys that allow adjustments of application dependent parameters, if
required, while observing the results of these adjustments. Application dependent
parameters are the Low and High Limit Cursors and the Noise Cursor. In most cases, only
the Noise Cursor will be required to be adjusted.
