    Overview The CrimpTest-1 kN calibration checking rig is designed for verifying the accuracy of the loadcell readings. For the user, this ensures that a unit does not continue to be used with inaccurate readings across its range. Authorised personnel, such as Mecmesin or your distributor, can adjust the loadcell readings, but this does not replace the need for periodic certified recalibration.
