loosened before the housing will turn. [refer to p. 24]
4.
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.
