What is a Torque Tester?
A torque tester is used as a quality control device to test or calibrate torque controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers
Robb Precision Tool Services conducted one day training at Perkins Pacific.
Robert Robb, owner of RPTS held one day training on correct use of the CDI Digital Torque Tester at Perkins Pacific, Ridgefield, WA.
To ensure safety and reliability of torque wrenches and torque instruments it is essential the technicians are educated on proper use. Using a quality torque tester correctly makes a safer world through accuracy and precision. Preventing scrapped work, product recall or injury.
Robert Robb, owner. ” Customers want it quick and easy to check for accuracy of their torque wrenches, but don’t know the correct way to use the torque tester. I saw the need for educating the technicians and I decided to offer to them and train the employees how to use it correcly. ”
A representative from our A2LA certified laboratory will perform the training from mounting the tester correctly to downloading the stored torque data to the PC. They will receive a certification of completion as an authorized person to test and calibrate torque instruments, including torque wrenches, manufactured by Snap-on/CDI.

What is A2LA ISO/IEC 17025 Accredited Calibration?
A2LA stands for the American Association for Laboratory Accreditation. It is a nonprofit 3rd party institution that accredits calibration labs and preforms thorough assessment of all factors of testing and calibration to the ISO 17025 standard. A2LA laboratories are audited regularly to ensure their continued compliance with requirements and to check that their standard of operation is being maintained. Lab technicians may be required to take part in comprehensive and ongoing intense testing to ensure the most recent methods are being followed.
Is the most important standard for calibration and testing laboratories around the world. Laboratories that are accredited to this international standard are required to include factors which determine the correctness and reliability of the tests and calibrations preformed in the laboratory by a qualified technician. Factors that are included are environment control; equipment and measurement traceability; testing methodology; and reporting of test and calibration results.
The benefits of A2LA ISO/IEC 17025 certification:
- To ensure that calibration and testing are accurate and reliable.
- Laboratories comply with internationally recognized standard.
- Increase confidence in Testing and Calibration.
- Save costs on an incorrect indication. Which can cause rework, scrapped product , product recall or injury.

Torque Wrench Usage
• All mechanical torque wrenches are calibrated from 20% to 100% of full scale, therefore, they
should never be used below or above those limits
• To determine which torque wrench capacity is best suited for an application, many factors must
be considered. However, as a recommendation, use a torque wrench in the middle 50% of the
overall capacity of the tool. This will result in longer tool life, ease of use for the operator and
increased accuracy from “clicker” type torque wrenches
• Always grasp handle fi rmly in the center of the grip
• Approach fi nal torque slowly and evenly
• Stop pulling wrench immediately when target torque is reached
• Never use a torque wrench to break fasteners loose
• Should be cleaned and stored properly
• Should always be stored at it’s lowest torque setting
• Wrenches should be re-calibrated if dropped. Should never be used in excess of it’s capacity
• Torque wrenches should be “exercised” a minimum of three times at 100% of full scale before
• The wrench selected should be calibrated in the same torque units that are specifi ed
• Use of a “cheater bar” will result in an inaccurate reading and can possibly damage the wrench
• Torque wrenches will last longer if reasonable care is taken. Always unwind handle to the lowest
setting after each use. Do not attempt to lubricate the internal torque mechanism. Clean torque
wrench by wiping, do not immerse. The wrench should be sent to a qualifi ed calibration lab once
every year or every 5000 cycles for re-calibration
