1、RANGE AND ACCURACY: 3/4 inch drive digital torsion wrench, with a buzzing setting range of 42.5‑850N.M. With a clockwise accuracy tolerance of ±2.5% and a counterclockwise tolerance of 3.5%. 2、PRESET AND STORAGE: This digital torsion wrench has preset mode and 100 sets of data storage function, which can preset and store 6 sets of torsion and angle values, making it efficient and practical. 3、ALARM FUNCTION: When you approach the target torsion, the buzzer will emit a regular beep sound, and the LED indicator will change from a flashing green to a stable red light, reminding you to stop applying force. 4、UNITS AND MODES: Provide 4 real time torsion measurements of N.m, in lb, ft lb, kg.cm. In track mode, balance force can be applied by changing the displayed value. In peak mode, the torsion value generated will be recorded. 5、LOCKING AND SLEEP MODE: This torsion wrench has a locking mode to avoid accidental contact with numerical values. When you do not use a torsion wrench, it automatically enters sleep mode after 2 minutes.
