8. Instructions for engaging fall weight
When engaging the fall weight in the release mechanism, please use both thumbs as shown in
the sketch.
The fall weight is lifted up as far as possible with both hands until shortly underneath the limit
stop so that it can be pressed into the stop using both thumbs as shown in the sketch. Use your
thumbs to lift the fall weight up slowly until it engages in the release mechanism.
This avoids engaging the weight too harshly, which can lead to faulty measurements.
