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.

% 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.
