Reset Program
The
Pr.01 program enables you to do a reset, refreshing the SmartSonic measurement reading, while not changing data
saved in other programs. After resetting, the actual reading is shown on the LCD, and SmartSonic begins to scan. This
program has the same effect as turning the unit off then on.
NOTE: During the reset, SmartSonic will display 8.8.8.8 and the output current will be 22mA.

Tank Height Program
The
Pr.02 program enables you to enter the Tank Height. The default value is the maximum measurement range
selected for your unit ( Pr.23). If you enter a value that exceeds this highest value, the Err error message is displayed, and
the value is not saved.
NOTE: For the Tank Height you should enter the distance from the edge of the sensor housing (not the face of the
transducer) to the bottom of the tank. For Open Channel Flow, precisely measure to the bottom of the flume or weir
directly below the sensor.
The
Pr.02 program also gives you access to the Initial Set-up Programs (previous section). There are also other functions
that can be accessed through the Pr.02 Program (these will be discussed later in this section).
The following shows the potential values for “Tank Height”, “Span Range” (the difference between 4mA and 20mA points),
and “Minimum Dead Zone” (the Dead Zone can be expanded up to 4.9 ft.).
The next table shows how to set the Tank Height:
