Sensor I® Expert User Manual

INTRODUCTION

The SENSOR 1® EXPERT WRENCH is a hand-operated portable tightening system with a battery-powered microprocessor control system. In addition to standard torque and angle control tightening capabilities, it provides a Yield Control mode of tightening and Dynamic Torque Auditing. It is suitable for laboratory, production, quality control, maintenance and field service.

The control system is powered by a rechargeable NiMH battery located inside the wrench handle (model 125, 250 & 400) or in the lower portion of the control unit (model 40). The wrench has a toggle lever used to select the ratchet direction. Angle reference is either measured internally by the EZ angle or via an attachable spring arm with a magnet (EA-models). Attachable spring arms can be fitted with options such as suction cups or alligator clips.

The digital display shows a digital readout of either dynamic torque peak torque, or angle. Audible signals and displays indicate the completion of tightening for Dynamic Torque Audit, Torque Control, Yield Control (elastic limit of bolt), or Angle Control procedures.
