9.1.4. Min Range ( 3.0 )
Min Range establishes the dimension of the measurement blanking-zone near the
sensor. It is referenced to the top of the tank.
Min Range must be at least the value of Zero Adjust plus 1 foot.
The range for Min Range is: 1.0 ft to 32.0 ft
9.1.5. Auto Gain ( ON )
This parameter determines whether the Auto Gain function is operational. When
activated, Auto Gain continually monitors signal characteristics and adjusts signal
amplification in response to changes in the process environment. It is recommended
that Auto Gain remain ON unless otherwise advised by a factory-trained technician.
The options for Auto Gain are: ON and OFF
9.1.6. Current Gain ( 30 )
With Auto Gain ON, Current Gain is established automatically and is not accessible
as a parameter that can be modified manually. With Auto Gain OFF, this parameter
establishes the constant level of signal amplification at which the instrument will
operate.
The range for Current Gain is: 0 to 100
9.1.7.
AG Set Point (Auto Gain Set Point)
( 10 )
The AG Set Point determines the relative signal strength that the Auto Gain routine
will seek. Increase this parameter to cause Auto Gain to seek a generally higher
level of signal amplification. Decrease this parameter to cause Auto Gain to seek a
generally lower level of signal amplification.
The range for AG Set Point is: 5 to 50
9.1.8. Update Rate ( 10 )
Update Rate determines the number of signal data sets used to develop the current
signal waveform and update the current measurement. This setting effectively
establishes the instrument response time, ranging proportionately from
approximately 2 – 10 seconds.
The range for Update Rate is: 1 to 20
9.1.9. Interface ( First )
The Interface parameter establishes the primary Level or Range measurement
algorithm.
