a new value and press
The default value for this parameter is –275.0 ft/sec (–85 m/sec) and
values from –500 to 500 ft/sec (–150 to 150 m/sec) are acceptable.
The
E3: VELOCITY RANGE
calculated fluid velocity is less than the programmed
LOW LIMIT value. See the Service Manual for a discussion of error
codes.
4. Press [ENT] to accept the current Velocity High Limit value or
enter a new value and press
The default value for this parameter is 275.0 ft/sec (85 m/sec) and
values from –500 to 500 ft/sec (–150 to 150 m/sec) are acceptable.
The
E3: VELOCITY RANGE
calculated fluid velocity exceeds the programmed
LIMIT value. See the Service Manual for a discussion of error codes.
5. Press to accept the current Acceleration value or enter a new

value and press
[ENT]
The default value for this parameter is 100.0 ft/sec

6. Press [ENT] to accept the current Amp. Discrim Low value or enter
a new value and press
IMPORTANT: Consult the factory before performing this step.
The amplitude discriminator measures the size of the transducer
signal received by the Model GF868. The default value for this
parameter is 14 and values from 0 to 100 are acceptable. The
error message appears when the amplitude
