US Patent 11685028 Hydraulic crimper tool

A power tool system includes a hydraulic power tool. The hydraulic power tool includes a hydraulic drive, a sensor, and a first electronic processor. The sensor is configured to detect an operational parameter of the hydraulic drive during an operation by the hydraulic drive. The first electronic processor is configured to store a plurality of data points based on the operational parameter detected during the operation and send the plurality of data points to an external device. The external device includes a display screen and a second electronic processor configured to receive the plurality of data points from the hydraulic power tool, control the display screen to display an expected data point for the operational parameter for the operation, and control the display screen to display an actual data curve based on the plurality of data points, the actual data curve overlaid on the expected data point.
