Note
For measurements that require a higher measuring accuracy, factory calibrated measuring
chains are available.
Accuracy of measuring chains different from the standard measuring chain
Add the measurement inaccuracies in
accuracy of measuring chains different from the standard measuring chain. The
incremental scale factor (ISF) error is typically ±5%, this applies to 90% of the measuring
range.
