Ensuring that the tools used to apply torque and those used for auditing have been properly calibrated and remain in calibration is the foundation of every torque program. "Best practice" for today's programs includes a two-step system of certifying and regularly checking each tool.
The first step in a "Best practice" system is certifying tools, which would typically require test equipment of the highest accuracy and the use of mechnaical loaders. Often the capability of testing a wide range of tools in necessary. The use of multiple sensors with a single test device, such as the PTM or System 5 with a mechnical loader, is the generally the most cost effective alternative for certifying tools.
The second step is the regular checking of tools, usually performed by the user of the tool. The tester used for this purpose would require simplicity of operation, ease of use and be readily accessible. Not suprisingly the cost and durability are significant factors when purchasing testers for this application. Torq-Tronics and VeriTorq have been designed to meet the needs of this user and the purchasing department.
