The EZ-TorQ II product utilizes hardware level low pass filters prior to A/D conversion and software averaging to clean
the main signal and remove undesired frequency signals which may be a result of noise which can occur during dynamic
motion. Three filter settings are provided, as described below.
1. Pan-Pacific (130Hz):
At this frequency setting, the operator will see a decrease in torque values displayed as the
speed of the power tool is increased. The 130Hz frequency filter in conjunction with software averaging cuts off signals
above 130Hz, which will result in slightly lower torque values being displayed with increased RPM.
2. Mountz (170Hz):
At this frequency setting, the operator will see limited or no change to the torque values being dis-
played as the speed of a power tool is increased. The 170Hz frequency filter in conjunction with software averaging cuts
off signals above 170Hz, which will result in little or no change to torque values being displayed with increased RPM.
3. ISO (500Hz):
At this frequency setting, the operator will see an increase in torque values displayed as the speed of
the power tool is increased. The 500Hz frequency filter in conjunction with software averaging cuts off signals above
500Hz, which will result in higher torque values being displayed with increased RPM. The 500Hz frequency setting is
offered for customers seeking to test power tools in accordance the ISO standard ISO 5393.
