The E1:LOW SIGNAL error message appears when the
signal strength falls below the programmed SIGNAL
40
LOW LIMIT value. See Chapter 5, Error Codes, for a
discussion of error codes.
The E4: SIGNAL QUALITY error message appears when
the signal quality falls below the programmed COR.
100
PEAK LIMIT value. See Chapter 5, Error Codes, for a
discussion of error codes.
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
20%
more than the programmed SOUNDSPEED ± LIMIT
value. See Chapter 5, Error Codes, for a discussion of
error codes.
The E3: VELOCITY RANGE error messages appears
–40.0 ft/sec
when the calculated fluid velocity is less than the
(–12 m/sec) programmed VELOCITY LOW LIMIT value. See
Chapter 5, Error Codes, for a discussion of error codes.
The E3: VELOCITY RANGE error messages appears
40.0 ft/sec
when the calculated fluid velocity exceeds the
(12 m/sec) programmed VELOCITY HIGH LIMIT value. See
Chapter 5, Error Codes, for a discussion of error codes.
The E6: CYCLE SKIP error message appears when the

calculated fluid velocity changes by more than the
15.0 ft/sec
programmed ACCLERATION LIMIT value from one

The amplitude measures the transducer signal received
by the Model AT868. The E5: AMPLITUDE error
message appears when the amplitude discriminator
14
falls below the programmed AMP. DISCRIM. LOW value.
See Chapter 5, Error Codes, for a discussion of error
codes.
The amplitude discriminator measures the transducer
signal received by the Model AT868. The
E5: AMPLITUDE error message appears when the
34
amplitude discriminator exceeds the programmed AMP.
DISCRIM. LOW value. See Chapter 5, Error Codes, for a
discussion of error codes.
