Illustrating the method for determining the physical offset for a rotated Peak
Combo Sensor
 Surface Combo Sensor/Ultrasonic Depth Sensor
Physical Offset Measure the distance from the crown
(top) of the pipe to the face of the sensor (horizontal
surface with the two depth crystals) to determine the
physical offset. Typical offsets range from 1.25 to 1.50
inches (32 to 38 mm).
Note: These offsets are required when configuring the
monitor using the Qstart software.
11. Secure the sensor cables from the ring to the location at which
the monitor is mounted in the manhole. Refer to Securing the
Sensor Cables in the Pipe and Manhole on page 3-64 for more
information.
