Calibrating BRx6 Sensors in SurvCE/SurvPC
This guide is a quick overview of the steps to follow when calibrating the BRx6 sensors using
SurvCE/SurvPC version 5.05 or higher. A longer more detailed guide titled “BRx6 Sensor Calibration
using SurvCE/SurvPC” can be found on the Carlson website in the Knowledgebase.
o Launch SurvCE
o In Equip/Rover/Receiver, the Use IMU box must be checked.
Step 1: Calibrate the Tilt Sensors
o Mount the BRx6 on a calibrated level tribrach or pole.
o Go to Equip/GNSS Utilities. Press the button for Sensor Calibration and then choose Full
Calibration. Select 1. Tilt Calibration (set hz)
o The electronic bubble displayed on the screen. Make sure the BRx6 is level, and then press the
“Calibrate” button to zero the tilt sensors. The electronic bubble should now be centered.
o If you are only using the electronic bubble in SurvCE, calibration is complete. If you wish to use
Tilted Pole correction feature in SurvCE, then proceed and complete steps 2 and 3.
Step 2: Magnetic Step-by-Step
o Attach the BRx6 to a tribrach or pole for the vertical spin as
shown
o Tap the 2.Magnetic Spin button to start Step 2
o Tap the Start Vertical button
o Slowly rotate the BRx6 as shown until the vertical progress bar is
complete.
