The Diagnostic Data menu screen provides one location where all diagnostic data can be viewed. Please note, adjustments can not be made on this screen. Adjustments can only be made on the Spectra Graph.

DIAGNOSTIC DATA

APPLICATION INFORMATION	FUNCTION / EXPLANATION
Low Limit	High Pass Filter Setting
High Limit	Low Pass Filter Setting
Noise Level Set	Noise Filter Setting
Doppler Frequency (Hz)	Average FFT Frequency
% Deviation	The width of Spectra is used to determine beam
	penetration and calibration. The selection of
	“Slurry” in Application Data is recommended for
	flow rate indication accuracy when the % Devia-
	tion is less than 25. For % Deviation above 35
	the use of “Liquid” is recommended.
	For applications that continuously have % De-
	viation between 25 and 35 proper selection of ei-
	ther Liquid or Slurry can be confirmed by com-
	parison to a known flow reference.
Signal Peak-to-Peak mV	Peak-to-Peak demodulation signal amplitude.
	The acceptable range is between 100 and 3200
	mV during typical flow conditions. If less than 100
	mV, check transducer type used and mounting
	configuration. If greater than 3200 mV, try in-line
	mounting and/or “detune” Carrier Fx.
FFT s/sec	Number of FFTs per second
FFT Peak	Peak FFT Amplitude
Carrier Fx	Transmit Frequency code
