Signal
Parameters Range
Default
Value Miscellaneous Information
Signal Low
Limit
-20 to 100 40
The E1:LOW SIGNAL error message appears when the
signal strength falls below the programmed SIGNAL
LOW LIMIT value. See Chapter 5, Error Codes, for a
discussion of error codes.
Correlation
Peak Limit
0 to 500 100
The E4: SIGNAL QUALITY error message appears when
the signal quality falls below the programmed COR.
PEAK LIMIT value. See Chapter 5, Error Codes, for a
discussion of error codes.
Soundspeed
± Limit
1 to 50% 20%
The E2:SOUNDSPEED error message appears when the
calculated fluid sound speed differs from the fluid
sound speed entered in the Channelx-System menu by
more than the programmed SOUNDSPEED ± LIMIT
value. See Chapter 5, Error Codes, for a discussion of
error codes.
Velocity Low
Limit
–328 to 328
ft/sec
(–100 to
100 m/sec)
–40.0 ft/sec
(–12 m/sec)
The E3: VELOCITY RANGE error messages appears
when the calculated fluid velocity is less than the
programmed VELOCITY LOW LIMIT value. See
Chapter 5, Error Codes, for a discussion of error codes.
Velocity High
Limit
–328 to 328
ft/sec
(–100 to
100 m/sec)
40.0 ft/sec
(12 m/sec)
The E3: VELOCITY RANGE error messages appears
when the calculated fluid velocity exceeds the
programmed VELOCITY HIGH LIMIT value. See
Chapter 5, Error Codes, for a discussion of error codes.
Acceleration
Limit
0 to 100
ft/sec
2
(0 to 30
m/sec
2
)
15.0 ft/sec
2
(4.6 m/sec
2
)
The E6: CYCLE SKIP error message appears when the
calculated fluid velocity changes by more than the
programmed ACCLERATION LIMIT value from one
reading to the next. See Chapter 5, Error Codes, for a
discussion of error codes.
Amplitude
Discriminator
Low
0 to 100 14
The amplitude measures the transducer signal received
by the Model AT868. The E5: AMPLITUDE error
message appears when the amplitude discriminator
falls below the programmed AMP. DISCRIM. LOW value.
See Chapter 5, Error Codes, for a discussion of error
codes.
Amplitude
Discriminator
High
0 to 100 34
The amplitude discriminator measures the transducer
signal received by the Model AT868. The
E5: AMPLITUDE error message appears when the
amplitude discriminator exceeds the programmed AMP.
DISCRIM. LOW value. See Chapter 5, Error Codes, for a
discussion of error codes.
