the
The E4: SIGNAL QUALITY error message appears when the signal quality
100 falls below the programmed COR. PEAK LIMIT value. See Chapter 2 in the
Service Manual
The E2:SOUNDSPEED error message appears when the calculated fluid
sound speed differs from the fluid sound speed entered in the Chan-
20%
nelx-System menu by more than the programmed SOUNDSPEED
± LIMIT value. See Chapter 2 in the
error codes.
The E3: VELOCITY RANGE error messages appears when the calculated
fluid velocity is less than the programmed VELOCITY LOW LIMIT value.

The amplitude discriminator measures the transducer signal received
by the Model XGS868i. The default value for the above parameter is 14,
and values from 0 to 100 are acceptable. The E5: AMPLITUDE error
14
message appears when the amplitude discriminator falls below the
programmed AMP. DISCRIM LOW value. See Chapter 2 in the
Manual
for a discussion of error codes.
The amplitude discriminator measures the transducer signal received
by the Model XGS868i. The default value for the above parameter is 34,
and values from 0 to 100 are acceptable. The E5: AMPLITUDE error
34
message appears when the amplitude discriminator exceeds the
programmed AMP. DISCRIM HIGH value. See Chapter 2 in the
Manual
for a discussion of error codes.
An offset between the upstream and downstream transit times is speci-
0 μsec
fied at this prompt.
At this prompt, specify a time measurement offset that compensates for
58 μsec any shift resulting from cross-correlation. Set to 0 for active Skan T
Offset.
The percentage of peak used to calculate the transit times and Delta T is
50%
specified at this prompt.
