3. Select Use Pitch/Roll?
•
Click No if the RiverPro/RioPro will not be subject to pitch and roll (i.e. calm water) (see
Figure 15). This calibration requires two rotations (one for calibration and one for
verification).
•
Click Yes if RiverRay, RiverPro/RioPro, or StreamPro will be subject to pitch and roll (see
Figure 16). This calibration requires up to eight rotations (four for calibration and four for
verification) while pitching the StreamPro up and down.
4. If needed, click the Factory Default button to restore the factory calibration values.
Use the
Factory Default
button if your compass has problems calibrating or instructed to by
TRDI field service.
5. Click the Start Calibration button.
6. As you rotate the RiverPro/RioPro, the bars will change color. The Blue bar indicates where you
are in the rotations.
•
Green – Good
•
Light Green – Acceptable
•
Yellow – Within parameters (one or two yellow bars for the entire rotation is OK)
•
Orange – Unacceptable - Rotate slower!
•
Red – Not measured
7. When the first rotation(s) are complete, click OK on the message box to continue with the verifi-
cation samples.
8. When the second rotation(s) are complete, click OK on the message box. The calibration error
should be less than 2 degrees.

The no Pitch/Roll calibration (also called a single-tilt calibration) requires two rotations while the
RiverPro/RioPro is on a flat, level surface.
