10. Click on the Read button to prompt the monitor to take depth
and velocity measurements.
The Monitor Measurement section displays the depth and
velocity readings taken by the monitor.
11. Compare the manual field measurements to the sensor
readings. If a difference exists between the manual depth
measurements and the depth sensor measurements, you can
compensate for this difference by editing the
electronic offset
parameter for the appropriate depth sensor. Consider applying
this offset to ensure the monitor produces the most accurate
data. Use the following equation to determine the electronic
offset:
Field Depth = Sensor Depth + Electronic Offset
12. If the sensor reading is low , add a positive (+) electronic offset.
13. If the sensor reading is high , add a negative (-) electronic
offset.
Note:
Exercise caution when applying an electronic
offset. Use an offset only when you are confident in the
accuracy and reliability of the manual measurements and
physical offset of the sensor.
If a difference exists between the manual velocity
measurements and the velocity sensor measurements, you can
compensate for this difference by adjusting certain velocity
sensor parameters, particularly Maximum Velocity and
Sensitivity.
Note:
If you change a device parameter, such as an
electronic offset, you must reactivate the monitor.
14. ( optional ) Click on the Read button again to take additional
measurements, if necessary.
15. Click on the Close button once you are finished performing
confirmations for the selected device to exit the Confirm
Device dialog.
