The torque wrench tester of the PCE-TWM series can test torque wrenches up to 500 Nm, depending on the sensor. Due to the precise evaluation electronics, the torque wrench tester has a measurement accuracy of 0.5 % of the measurement range. The torque wrench is fixed by means of a 1/4' female square. The torque wrench tester consists of an evaluation unit and an external torque transducer with a cable which makes the measurement setup convenient. Torque wrenches can be tested in both directions. The limit value function of the torque wrench tester makes it possible to set an acoustic alarm which is triggered when a pre-set torque is reached. The torque wrench tester indicates the PEAK value (maximum value display) as well as the force path and also offers the possibility of a statistical evaluation of the measurement process. The measurement results can be saved to an internal SD card and can be read out on the device or a PC. The downloadable PC software for the torque wrench tester is included in the standard delivery.
