How to use the film ruler

How to use the film ruler as follows:

Take the film ruler out of the box, place two 10x magnifying glasses, place the film ruler horizontally on the stage, move the magnifying glass A and prevent it from the 0 position (0 point) or place it at any starting point you want to measure. The reading can be obtained by moving the magnifying glass B to the desired measurement position. Then you can measure one by one in the same way.
