How To Re-calibrate A Torque Wrench. Torque wrenches should also often be checked for defective parts or general wear and tear.

To calibrate a torque wrench, you have to setup a known torque and adjust the wrench to correctly act at that setting (ie: If your wrench is off then this setting will not be at the 50 ft pound mark but at a different distance. Step six into the correct machine on stage correction.
The torque wrench has the option of measuring distance in inch pounds or foot pounds.
There are no hard and fast rules about how long a torque wrench will stay calibrated.

It is advisable to bring the wrench in to a calibration lab on an annual basis or after every four to five thousand cycles. The measure of radial force exerted by the torque wrench is measured and compared to its set torque value to ensure that it is actually within the torque wrench accuracy ranges allowed by the international organization for standardization (iso).
