What does 'Torque Filter' mean?

The Ingersoll Rand Electric Tool Controllers have user selectable filtering for the torque transducer signals.

The Torque Filter parameter is used to filter high frequency noise or “ripple” from the torque signal from the strain-gage transducer to provide a more accurate torque measurement.

The value selected represents the bandwidth of the filter.
As a guideline, use lower values for soft joints such as gasket applications, or those that generate a high angle of rotation, and higher values for hard joints, or those that generate a low angle of rotation.

When calibrating DC Electric tools, it is advantageous to set the external transducer monitor to the same filter frequency as the Insight Controller, in order to get accurate correlation between the two devices.
