4. Use the Up / Down push-buttons to make the display read the level (in feet of water)
that your 20mA signal represents. Note: It is slow to change at first.
(Alternate Procedure - Use the Up / Down push-buttons t make the display read the
number of feet of water that the pressure transducer or the end of the bubbler tube is
submerged under.
5. Repeat the procedure above for the “LEVEL INPUT ZERO” Parameter.

Notes:
1. Level Display Span is what is displayed with a 20mA Level Input.
2. Parameter P.36 is used to set the decimal point position.
3. To find the Level Input Span Setting for other transducers, use the following equation:
Pressure (PSI) x 2.309 = Level (feet of water)
