• the special power transmission system prevents the force application point from shifting
• the handwheel drives a lever linearly via a spindle, whereby this movement is converted into a rotary movement for the transducer
• 2 ball-bearing bushings ensure a friction-free contact surface and enable the horizontal alignment of the wrench
• the torque wrench remains in position whilst the load is being applied
• minimal transverse forces and reduced friction minimise measurement errors
• protected by national and international patents

  Contains: transducer, square adaptor, USB adaptor, cable, management software for calibration certificates

The perfectControl® calibration system with manual drive reduces the effort and time required for calibrations and adjustments of torque wrenches.

• measures without shifting the point of application of force
• avoid incorrect measurements with the precise bearing spindle and ergonomically shaped handwheel
• extremely precise calibration thanks to optimisation of the bearings and the square drives of the transducers
• clicking and indicating torque wrenches can be calibrated
• quick and easy switching of transducers with QuickRelease locking system
• bridge support with an eccentric clamp designed for single-handed operation reduces time and effort
• automatic transfer of measured values via USB interface to PC for further processing and archiving
• a calibration certificate can be printed and/or saved as a PDF file after calibration
• ‘as found’ and ‘as left’ calibrations can be documented
• DIN EN ISO 6789 calibration is supported in numerous languages. Additional standards and factory specifications available upon request
• calibrations up to 1,000 N·m with easy-to-assemble extension No. 7791-1.
• calibration of transducers using torque reference wrenches is possible on request
• the interface adaptor set 7761/3 is required for automated calibration of electromechanical torque wrenches and screwdrivers (730D eClick, 714, 766 DAPTIQ®, TORSIOTRONIC®, TORSIOTRONIC® DAPTIQ®)
