Geomatrix - Model G-882 - Digital Accessory Board - Datasheet

Each G-882 will have slightly different scale and bias values from one another. Meaning it is not possible to use the scale and bias values from another G-882, even if the same altimeter is used in both fish. If an altimeter is replace with one of a different range, say 50m 200KHz, then the scale and bias will have to be recalculated, which is time consuming especially when companies are managing over eight magnetometers on a vessel.
