the deflection and on the other side the deflection force. The measured values are indicated on a
scale via o-rings. See figure 5.7 on page 46.
1. Slide the lower O-ring on the deflection scale to the required value, according to the tables.
Set the upper O-ring to the ”0” line of the deflection force scale.
2. Set the tension tester vertically to the strand in its center. Apply force to the top of the tester
so that the adjusted deflection value is reached. A steel straight edge should be helpful to
read the scale.
3. The upper O-ring has now moved downwards and shows the deflection force. Read the
value at the upper edge of the O-ring.
