manual abstract
The release mechanism enables sockets to be removed and changed quickly at the push of a button. The required torque is quickly set via a pull-out setting knob in the handle. When the preset torque is attained, the wrench produces both audible and tactile signals. Right-hand turn for controlled screw tightening. Accuracy is in accordance with DIN/ISO 6789.1993, EN26789.1994 User friendly designed, comfortable handle Chromium-plated With test certificate in accordance with DIN/ISO 6789.1993, EN26789.1994 Measuring Range in Nm = Newton-Metre Art.

For various reasons, it may be necessary in practice to add an extension arm. To this end it is necessary to adjust the programming. The required settings may be calculated using the following formula: L1 = Length of the lever arm on the torque wrench itself B = Distance between the two pivot centres after attaching the extension T = Tightening torque of the bolt C = Setting value L1 x T L1 + B 7451-DEMO-KIT Example: L1 = 425 mm B = 40 mm C = T = 20 Nm C = ? 0,425 x 20 0,425 + 0,040 18,28 Nm 8,5 0,465 18,28 C Torque Angle Gauge Automotive manufacturers prescribe both torque and rotational angle settings for fastening elements used in vehicles. Angle controlled torquing gives initially “snug” torque, then turns the fastener a step further to the optimum torquing angle. Torque is measured to the maximum safe working load, while preventing overtorquing and damage to the fasteners. Large, easy to read scale with oil resistant, non-reflective surface. The angle indicator clearly indicates the angular reading. The adjustable reference arm is firmly attached to a non-moving part of the machine and prevents the scale turning.
