Appendix C. 4 to 20 mA Operation
C.1 Setting Operating Parameters using DIP
Switches
The following 4 to 20 mA operating parameters can be set with DIP switches.
DIP switches 1, 2, and 3 are reserved for the SDI-12 interface.
Setting measurement type to level or depth
• Level Measurement – Set DIP Switch 4 to the OFF position.
• Depth Measurement – Set DIP Switch 4 to the ON position.
Scaling the measurement
With DIPS 5 and 6 you can scale the available measuring range to a smaller
range. Where the whole measuring range is not required, this has the
advantage of increasing the resolution.
• 50 ft (not scaled) – DIPS 5 and 6 to the ON position.
• 25 ft – DIP 5 to the OFF position, DIP 6 to the ON position.
• 12 ft – DIP 5 to the ON position, DIP 6 to the OFF position.
• 6 ft – DIPS 5 and 6 to the OFF position.
Setting the measurement system
Use DIP 7 to set the engineering units of the measurement.
• Metric – DIP 7 to OFF.
• Imperial – DIP 7 to ON.
Setting measurement type
Use DIP 8 to set water level or pressure units.
• Water Level – DIP 8 to OFF.
• Pressure – DIP 8 to ON.
