Wireless Torque Wrenches enables user to transfer measurement data directly to the collecting data system after each tightening operation. To establish communication between wrench (or screwdriver or tester) and PC, customer has to use Wireless Receiver – data receiving device, which can simultaneously collect data send from few different tools. Each tool sends data transmition which consist of : measured torque value, date, torque unit used during the measurement and torque settings – if they were applied. Each transmition includes also device serial number to enable full identification of the tool that have sent it. To collect data customer can use standard PCFE system which is delivered with the tools free of charge, or use transmition via RS232 connection – this way customer can send data to already existing data collecting system.
