GEO 7X HANDHELD: ORIENTATION SENSOR CALIBRATION

Solution

GEO 7X HANDHELD: ORIENTATION SENSOR CALIBRATION 

TYPES OF CALIBRATION 

The Geo 7X handheld is equipped with a field calibration utility to make calibrating the system sensors in the field simple and easy. The calibration utility recommends when you should perform the different calibration workflows, but in general the following rules apply: 

FULL CALIBRATION 

Full calibration recalibrates all orientation sensors on the handheld to the local environment and device state, taking into account your location and the temperature of the device. 

Full calibration should be performed: 

• the first time the device is used 

• if the device temperature or environment temperature has changed dramatically 

• whenever the calibration utility recommends Full Calibration 

• if after performing a fast calibration, sensor measurement still appear to be erroneous 

FAST CALIBRATION 

Fast calibration calibrates for local magnetic and environmental magnetic conditions. 

Fast calibration should be performed: 

• when you are about to begin data collection at a different job site 

• after swapping the battery 

• if you have dropped the handheld, or it is exposed to severe shock 

• if field applications are consistently reporting compass disturbance 

• if it appears that sensor outputs are erroneous
