Setting the 20mA and 4mA Values
SmartSonic enables you to set Distance, Level, Volume or Flow values to be used as 20mA and 4mA settings. The
default value for 20mA is the Tank Height (or the maximum Volume value), and the default value for 4mA is 0 (or the
minimum Volume value).
NOTES: The values for 20 mA and 4 mA must be different, otherwise an Err. 4 message is displayed. Both must also be
less than the tank height value, otherwise an Err. 7 message is displayed.
In both distance and level measurement modes, the dead-zone area affects the maximum values that can be
used for 20 mA/4 mA levels. The maximum 20 mA/4 mA value is tank height minus 0.4 m/1.3 ft.

Setting the Tank Height
You can enter the height of your tank using the
TANK h function. The default value is 39.4 feet. If you enter a value that
