Features: This torque tester is a must - have for production workshops to inspect torque wrenches. It automatically shows the percentage error between the measured and set values, eliminating manual calculations. With an accuracy of +/- 1%, it ensures precise results. It offers 4 torque measurement units, including ft/lb, in/lb, Nm, and Kg/cm, for flexible readouts. It comes with 3 useful modes: track, peak, and first. You can easily upload data via the USB interface. The backlit display makes it user - friendly even in dim working areas. It can run on a full - time AC connection or the built - in Li - ion battery, and the 10 - minute auto - shutdown feature helps extend battery life. It can be firmly fixed to a workbench or base plate using 4 screw bolts. Specifications: It meets or exceeds ASME specifications. The drive tang size is 1/2 in with a square drive type. It has a painted finish and is made of steel. The max torque is 250 ft/lb (339.0 Nm) and the min torque is 25 ft/lb (33.9 Nm). The torque accuracy (20 - 100% of full range) is +/- 1% clockwise. It comes with a 90 - day calibration and 1 - year parts warranty. Bench testers are great for on - the - spot use. They can be mounted on a bench or stand, feature a compact and durable design, and come with a rechargeable battery.
Using this torque tester is easy. First, connect it to a power source, either via the AC connection or use the built - in Li - ion battery. Select your preferred torque measurement unit (ft/lb, in/lb, Nm, or Kg/cm). Then, choose the appropriate mode (track, peak, or first) according to your needs. When inspecting a torque wrench, place it on the tester and let it do the work. It will show you the percentage error between the measured and set values automatically. Note that the tester has an accuracy of +/- 1%, so try to work within this tolerance range. If you're working in a dark area, use the backlit display for better visibility. To save battery life, let the auto - shutdown feature do its job after 10 minutes of inactivity. For maintenance, keep the tester clean and dry. If you need to calibrate it, refer to the 90 - day calibration service. And remember, it has a 1 - year parts warranty, so if there are any issues with the parts, you're covered.
