Summary
-
1.
Unequal arm lever systems with a gear ratio of 500–2,500 provide in an appropriate assembly the possibility of weighing 5,000 kg weights with an error of the order of 0.001–0.005%.
-
2.
These lever systems can be used as reference grade 1 dynamometers for measuring a force with an error not exceeding ±0.05% of the measured value.
-
3.
The adoption of the above lever dynamometers for metrological measurements will substitute in part the missing link in the measuring system, namely, the grade 1 dynamometers.
