Calibration Certificate
Each TRQ51402 ships with a serialized certificate of calibration listing the serial number, actual test results, and the test equipment and conditions used. Your certificate is your proof of the stated ±3% bidirectional accuracy — keep it with the wrench for warranty and recalibration records. Replacement certificate questions can be resolved through Tekton support referencing your wrench's serial number.

Why Full-Range ISO Calibration Matters
Torque wrenches calibrated only to ASME standards are not required to be accurate below 20% of their listed range. The TRQ51402 is calibrated to the ISO standard across the entire 10–100 ft-lb range, so low-torque fasteners get the same certified accuracy as high-torque ones.
Comparison and Alternatives
Against click-type wrenches without certificates, the TRQ51402 offers documented accuracy at roughly half its $110 list price. Compared with digital torque wrenches in the same price band, you get calibration certification and a 90-tooth head without batteries or electronics.
