When forming bubbles during use, a liquid compass has to be fluid-filled and bubble-removed in time in order not to be affected in accuracy.
Inside the compass box(or take out the compass to the left or to the right along the vertical axis of the compass. In this way, small bubbles inside the compass will gradually pile up at the wall of the compass body.
Continue to turn the compass body until the compass body is completely horizontally inverted and the bubbles are all into the automatic fluid-filling and bubble-removing device to perform the functions.
Again turn the compass body slowly to the left or to the right aling the compass vertical axis.
When the compass body returns to its horizontal position, the process of fluid-filling and bubble-removing is successfully completed.
