Motorised calibrating and adjusting tool from 1 to 400 N·m 7794-2

The electronic perfectControl calibrating unit with its electric drive considerably reduces the amount of effort and time required for calibration and adjustment tasks on torque wrenches. 

• measurement possible without moving the point of application of force.
• prevents faulty readings thanks to precision-mounted spindle and finely regulated motor.
• extremely accurate calibration thanks to optimised bearings and square drives for the transducers.
• rapid, easy change of transducers thanks to quick-release latching system.
• convenient pushbutton controls for clockwise and anticlockwise measurements with automatic speed compensation.
• saves time because the bridge support is locked in place using a single-handed eccentric lever.
• transmission of readings to a PC via USB interface for further processing, analysis and archiving.
• calibration certificates can be printed or saved as a PDF file after calibration.
• as found / as left calibrations can be documented.
• during calibration, DIN EN ISO 6789:2003 in numerous languages is supported. Additional standards and works standards are available on request.
• can be upgraded to perfectControl calibrating unit No 7794-3 for angle-controlled wrenches.
• calibration up to 1000 N·m is possible using the easily attached extension unit No 7791-1
• design patent, other patents applied for

Both clicking and indicating torque wrenches can be calibrated. Calibration of transducers is possible using reference torque wrenches No 7770-100 and 7770-1000, available on request.
