Effect of impact data

The effect of shock to the units, such as being dropped or struck with a spanner or wrench while installed. RT-Bolt was the most accurate, even after repeated severe impacts on the bolt.

Effect of bolt bending

Effect of bolt bending

The effect that bolt bending, generally caused by flange rotation, will have on the accuracy of the reading. RT-Bolt was the most accurate by comparison to all other methods.

Variability
