Kalibrado of torque wrench is the process for control and correct the accuracy of the tool. Accidental falls, changes of temperature and mechanical usage can affect the mode of torque wrench. Faligo of torque wrench on malmola surface can immediately break its kalibradon.
Even fall of four feet can distort the tool. Regular kalibrado guarantee precise indications of the torque wrench. That extends the uzvivos of the tool and secure it during work.
How to Calibrate a Torque Wrench
Control and preserve accuracy are inevitable for security and impact in every task that requires precise torques.
Control torquemantajn keys for accuracy regularly. The interior can compact because of oftega use or if the key stays fixita in too high value. Do not advise leave klakajn keys in nullity.
Fixu them in the most bottom torquemanta value for preserve right tension in the interior. That helps to extend the reliability of the kalibrado, but all torquemantaj keys necesas rekontrolon after a bit of time. Neither importa how well calibrated is the key, it toll accuracy during time.
For antaŭfiksa either regulebla key tested in one alone torque, the rezultato will be „well“ or „bad“. „Well“ show that the key reclines inside the tolerlimo, while „bad“ signal that it requires kalibradon. Forbearance of 3% until 4% in the torquemanta value is standard.
Kalibrado happen kompareante the indications of the torquemanta key with standard reference or very precise tensiometra trap in controlled laboratory.
If you require high accuracy for important tasks as machinery in fabrikaĵoj either aŭtomobilŝiparado, send the key to professional kalibrada service for punctual corrections. The atestilo of kalibrado will receive detail for every torquemanta key. It stores trend, place, state, intervalon and specifications of the kalibrado.
It points also the fikspunkton for antaŭfiksa type, the date of finito, the forthcoming kalibradan date, the accuracy in front and after the process. Moreover it calls the technician that certifide the key.
Simple mode control key are prepare known torque by means of long tubego and hanged weights. Take handle, flexible measure and known weight. For that, klampu the stirilon in the handle and turn it entirely horizontally.
Measure exactly 30 centimetres of the centre of the square ingingo. Hang the weight on the arm and control whether it shows the right value. Always measure of the centre of the square ingingo where the port engxatas.
