Realvision™ Ahrs Calibration; Troubleshooting; Operation Instructions - Raymarine RV-100 Installation Instructions Manual

6.1 RealVision™ AHRS calibration
RealVision™ transducers include a built-in AHRS (Attitude and Heading
Reference Sensor), which measures the motion of your vessel to assist in
the rendering of sonar images. After installation all RealVision™ transducers
require calibration.
An uncalibrated transducer can produce an offset to the front edge of the
render of the bottom in the sonar image, as illustrated below.
Uncalibrated
Calibration is an automatic process and starts after your vessel has turned
approximately 100° at a speed of between 3 –15 knots. Calibration requires
no user input, however at least a 270° turn is required before the calibration
process can determine the local deviation and apply a relevant offset.
The time it takes to complete the calibration process will vary according to the
characteristics of the vessel, the installation environment of the transducer,
and the levels of magnetic interference at the time of conducting the
process. Sources of significant magnetic interference may increase the time
required to complete the calibration process. Certain areas with substantial
magnetic deviation may require extra circles or "figure of 8" manoeuvres to
be performed. Examples of such sources of magnetic interference include:
• Vessel engines
• Vessel alternators
• Marine pontoons
• Metal-hulled vessels
• Underwater cables
System checks and troubleshooting
Calibrated
Note:
In some circumstances, it is beneficial to disable Realvision AHRS if local
sources of magnetic interference are distorting the sonar image. Realvision
AHRS can be disabled from [Settings].
[Menu > Settings > Sounder > AHRS stabilization]
Note:
The Calibration process will require repeating after a [Sonar reset] or MFD
[Factory reset].
