The unit is notwaterproofed and spillages should be avoided.THIS UNIT CONTAINS NO USER SERVICEABLE PARTS. ONLY QUALIFIEDSERVICE PERSONNEL SHOULD REPLACE OR FIT PARTS.BATTERIESProWrench Opta takes either two 1.5v Alkaline Manganese type ‘C’ cells (battery life -8 hours of continuous use) ora Crane supplied rechargeable cell pack (battery life -typically 8 hours of continuous use).
5INTRODUCTION Section 1OVERVIEWProWrench Opta‘s range of software features can be individually specified to give aconfiguration most suited to the requirements – from a simple no frills digital wrench toa comprehensive audit tool.The ProWrench Opta features two measurement modes for displaying either peak orreal time torque with a bar graph feature to give an analogue representation.Upper and lower limits can be set in peak mode, enabling the display and LED toindicate HI, OK or LO fastener status.The ProWrench Opta is designed to be point of load insensitive, which means that theoperator can be assured of correct measurement however the wrench is held andtorque is applied - particularly useful in limited access situations.ProWrench Opta is supplied with a dovetail (Sturtevant Richmont) interchangeablehead fitting, giving a wide range of head attachments to meet the assembly require-ments.When used in Jobs mode, the ProWrench Opta has the ability to store a large amountof date and time stamped readings for each of the fasteners audited. This data can beuploaded and stored on the PC with the use of the Opta Comms platform.Data from the ProWrench can either be printed or downloaded to a PC using anRS232 cable. Note: The ProWrench Opta cable has a 5 pin round connector to thewrench. This means the previous 4 pin cables for earlier ProWrench models cannot beused.

In the ProWrench II, this is set at 5% of therated span of the transducer.TargetThe target torque figure.
31ProWrench OptaTorque CycleA complete application of torque to ajoint starting from the torque risingabove the preset threshold value andfinishing at the preset cycle end time.Torque LimitsThe upper and lower limits for the torque application.Torque LSLThe Lower Specification Limit as set in the setup parameters.Torque USLThe Upper Specification Limit as set in the setup parameters.TraceA graphical representation of the torque cycle.TrackA type of measurement which follows the changing torque values imposed ona transducer as torque is applied. The display will return to zero after thetorque is removed.Units of MeasurementIt is possible with ProWrench Opta to measure torque, and convert internallyto display and store in any of the other torque measurement units as specified.
