Most of us men and some women adventurous enough to get involved in the upkeep of our equipment (read vehicles, bikes, apparatus or machines), have definitely heard of or used a torque wrench some time or the other. Essentially a tool in the garb of a socket wrench, torque wrench is used to help in tightening a nut or bolt by the specific application of a rotational force. The traditional torque wrench comes in the form of four types namely the beam wrench, the deflecting beam wrench, the click wrench and the no hub wrench and while functionally they served with a fair degree of accuracy, the requirement of a greater precision in the servicing of some contemporary equipment was felt due to the use of expensive specialized metals such as Titanium and carbon in their manufacture. The advent of the Digital Torque Wrench is the answer to this need.
So what exactly is a Digital Torque Wrench? Essentially the Digital Torque Wrench did the same task as the mentioned traditional wrenches but the difference was in the control of the applied force which could be now be exercised with a great deal of exactness. This could be achieved by stopping at the right moment while visually noting the readouts on a display of the digital torque meter built into the wrench or by simply pre-setting the required torque component according to specification and waiting for a warning tone or a flashing indication. These wrenches use a gauge to measure the strain developed on the torsion bar and subsequently transmits this information as a signal transformed into readable LED display of the digital torque meter. A useful feature of these wrenches is its capability of storing the readings of the exerted torque in its memory and this could be later retrieved on to a computer for the purpose of recording or assessment. The digital torque meter normally shows readings in the most frequently used Newton Meter (Nm) units but is capable of showing measurements in various other units too. In order to do this, the digital torque wrench has to be calibrated accordingly.
Digital Torque Wrench Calibration can be performed individually through following instructions in the product brochure, if given or from reference to several of the digital torque wrench reviews, which abound the net online. Briefly speaking, the digital torque wrench calibration involves first, a thorough inspection of the tool for any physical defect, which would need to be repaired including tightening of any screws or nuts. It is generally desirable that the entire procedure is conducted within a controlled environment. Next, a multi meter is used to connect to the wrench and for a selected voltage the readings are noted on the meter through a setting of zero value initially up to a number of 50 foot-pound intervals on the torque control. The read- outs of the voltage are then used in a calculation based on the average voltage per foot-pound of force to arrive at the desired digital torque wrench calibration.
