loosened before the housing will turn. [refer to p. 24]

Ensure correct probe depth setting. If using 1 ½" size

pipe, please see note on p. 23.

5. Open the housing. If needed, the orientation of

display can be rotated in 90° increments for a better

view.

[refer to p. 25 for more information]

6. Ensure power wiring [p. 34] and 4-20mA wiring

[p. 35 - p. 36] are properly connected. [refer to

Wiring section p. 32 for more information]

The Pulse/Alarm and serial communication wiring

options are based on model type.
