    • Minimum management cost On the conventional model, each device supports individual frequencies. On the model FH256MC, each one transmitter and receiver can support settings for all groups (256 models). Therefore, a minimum number of spare devices is required. • Easy transmitter/receiver setting Without removing the transmitter from the torque wrench or removing the receiver panel, the group and ID can be set and checked by wireless on the Setting BOX (option).
  • Page 7 • Reduction of causes of damages With the conventional model, a lead wire was used for the antenna. The FH256MC has a built-in antenna, which does not cause a breaking of wire. The case made of aluminum is robust.
