Enable and Disable Sensors

In section number 1 of the data-manipulation portion of the user interface, shown in Figure 8, it starts by selecting which of

the sensors are going to be included in sensor fusion.

'Enable Gyro' refers to 'Enable Gyroscope Sensor'.

'Enable Accel' refers to 'Enable Accelerometer'.

'Enable Mag' refers to 'Enable Magnetometer'.

Normally, gyroscope and accelerometer should always be enabled to provide necessary performance.

However, magnetometer should be turned off if the user scenario involves extremely complex and strong magnetic

interference. Please note that, after disabling the ‘Enable Mag’ option, magnetometer will not be directly used for sensor fusion

after boot is completed. However, this option does not affect Raw Data output nor the sensor fusion algorithm during boot

time.

Boot Mode

Boot Mode defines how the TransducerM behaviors when it is powered on, before entering its normal operation conditions.

You can change the ‘Boot mode’ option, as shown in Figure 22, within the Calibration box.

If ‘Static Mode’ is chosen, you have to keep the module stationary for at least 15 seconds during and after power on. Static

mode will provide relatively good performance possible by TransducerM immediately after. Note that the module should be sat

completely static during boot; any vibration during the 15 seconds will significantly reduce the performance.

If ‘Dynamic Mode’ is chosen, you can power on the TransducerM in a non-static environment, such as on a moving vehicle or

boat. The module will load the calibration data from the latest reliable calibration. Please note that, if the environment changes

significantly, for example temperature changes from 10 outdoor to 28℃ ℃ indoor, the calibration record may not be reliable

enough. When this happens, either of the following two methods can be used to improve the performance:

1. Keep the module stationary as required in the ‘Static Mode’ in the new environment for a while and until the yaw

heading drift be suppressed to a reasonable level;

2. Keep the module stationary as required in the ‘Static Mode’ in the new environment and then click 'Calibration Panel'

button to open the panel. Inside the panel, click the ‘CalibB’ button. Wait for 20 seconds to obtain the newest

calibration data and burn it into Flash Memory of TransducerM.

Please make sure power supply of TransducerM is stable while re-calibrating the module by clicking

the 'CalibB' button. Unstable power supply, and particularly a power-off event during the 20-seconds

calibration period, may result in unrecoverable damage to the module.
