  • Page 2 1. Outline CEM3-G-BTA is the digital torque & angle wrench. It can measure the torque and angle also does the judgments by the torque and angle. The Bluetooth® can output the data and judgment result wireless. Any other specifications and features are same as CEM3-G model.
  • Page 3 CEM3-G-BTA makes judgment due to lower, higher limit torque, lower, higher limit angle and double tightening detection angle if the tool is set. If you select the "M3 ID" output mode the output data string will has the 2 digit of judment result with data. (Refer 7.5 Output format for details) If you set the "NG_MAN"...

  • Page 6 3. Explanation of each mode The CEM3-G-BTA has two modes that are Measurement mode and Display mode 3.1. Measurement mode  Inspection mode (MODE-M) MODE-M is used for the re-tightening and breakaway inspections. If you set the high and low limit torque values the tool makes judgment the measured torque result.
