We put in here a tensionmeter, we put in here a tensionmeter and the bottom one, we hang on a string with a tensionmeter and then here we put four kilograms.
这儿放个张力计，这里也要一个，底下也有，一个张力计，挂着4kg物体。

To measure the tension in blades which are already under tension the tensionmeter should be assembled as described above BUT with the adjustable arm " IN" position.
