The Model 960 is a battery-operated, transient recorder with two transducer inputs and two angle inputs. It can serve as a portable threaded fastener laboratory for measuring fastener torque, angle, and clamp load. It is also ideal for auditing and certifying power tools and hand torque wrenches. The Model 960 is a cost-effective, versatile, and easy to use recorder and can collect up to 500 rundowns. Its alphanumeric setup and calibration menus assure ease of operation. It can be used with rotary torque-angle and clamp force transducers and other conventional strain gauge transducers.

Among many possible applications, the Model 960 is designed for the following:

• Perform torque versus tension verification testing on fasteners and joints to verify such things as coatings, lubricants, or plating performance
• Provide fastener torque versus angle signature analysis for clamp force verification
• Perform audit, certification, or tool room calibration of power tools and torque wrenches
• Perform dynamic monitoring of power tools on the plant floor to determine their performance capability
• Certify calibration factors for single spindle nutrunners and tools by monitoring the reference transducer and tool transducer simultaneously

After each rundown the Model 960 updates the statistics including high, within limits, and low level readings, standard deviation, and Cpk.

Data and statistics can be printed via the parallel port. Data can be downloaded to a PC via the serial port for further analysis. Program updates are uploaded through the serial port.

The Model 960 lets you capture real time and peak readings for torque-angle, torque-clamp load, or torque-time and immediately display or plot the following, based on your instrument setup:
