5 Calibrating the G Meter
Figure 4 Heart-G calibration
As referred previously the HEART-G includes a 3D accelerometer which is used to
measure the G-force acceleration acting on the pilot. Due to the gravitational pull of the
earth, at rest g-force acceleration on the pilot should be 1g. Should the accelerometer
become uncalibrated a different value may be shown, in this case the accelerometer can
be re-calibrated by following this procedure:
•
Remove the battery from the HEART-G
•
Put the HEART-G on a horizontal position (place it on a horizontal surface) with the
battery cover facing up.
•
Use one hand to touch both HEART-G electrodes and at the same time insert the
battery (ensure it is in the horizontal position see Figure 4 Heart-G calibration).
•
After inserting the battery within a period of 10 seconds, make contact with the
electrodes and release 3 times, this will cause the G-Meter to calibrate to 1g.
