Table 1-4: Transducer Signal Settings
Default
Value
The E1:LOW SIGNAL error message appears when the
signal strength falls below the programmed SIGNAL LOW
20
LIMIT value. See Chapter 2, Error Codes, in the Service
Manual for a discussion of error codes.
The E4: SIGNAL QUALITY error message appears when the
signal quality falls below the programmed COR. PEAK
100
LIMIT value. See Chapter 2, Error Codes, in the Service
Manual 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 more
20%
than the programmed SOUNDSPEED +- LIMIT value.
See Chapter 2, Error Codes, in the Service Manual for a
discussion of error codes.
The E3: VELOCITY RANGE error messages appears when
the calculated fluid velocity is less than the programmed
-75.0 ft/sec
VELOCITY LOW LIMIT value.
(-23 m/sec)
See Chapter 2, Error Codes, in the Service Manual for a
discussion of error codes.
The E3: VELOCITY RANGE error messages appears when
the calculated fluid velocity exceeds the programmed
75.0 ft/sec
VELOCITY HIGH LIMIT value.
(23 m/sec)
See Chapter 2, Error Codes, in the Service Manual for a
discussion of error codes.
The E6: CYCLE SKIP error message appears when the
calculated fluid velocity changes by more than the
50 ft/s
programmed ACCELERATION LIMIT value from one reading
(15 m/s)
to the next. See Chapter 2, Error Codes, in the Service
Manual for a discussion of error codes.
The amplitude discriminator measures the transducer
signal received by the XGS868. The default value for this
parameter is 14, and values from 0 to 100 are acceptable.
14
The E5: AMPLITUDE error message appears when the
amplitude discriminator falls below the programmed AMP.
DISCRIM LOW value. See Chapter 2, Error Codes, in the
Service Manual for a discussion of error codes.
The amplitude discriminator measures the transducer
signal received by the Model XGS868. The default value for
this parameter is 34. Values from 0 to 100 are acceptable.
34
The E5: AMPLITUDE error message appears when the
amplitude discriminator exceeds the programmed AMP.
DISCRIM HIGH value. See Chapter 2, Error Codes, in the
Service Manual for a discussion of error codes.
