2/35
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.
1.1. Features
・ Records in memory and outputs torque and angle at final tightening.
・ Capable of performing Pass/Fail judgments of tightening torque and angle.
・ Uses torque and angle values to detect double tightening (human error).
・ Built-in Bluetooth® module to transmit data wirelessly.
1.2. Judgment features
You can set the threshold for torque and angle, the tool judge the result by your settings.
Trg: Trigger torque, TL: Lower limit torque, TH：Higher limit torque,
θW: Double tightening detection angle, θL: Lower limit angle, θH: Higher limit angle
First digit alphabet describes torque judgment and second one does angle judgment.
First digit alphabet (Torque):
“O”: OK, “L”: Low NG, “H”: High NG
Second digit alphabet (Angle):
“D”: Double tightening detection NG, “O”: OK, “L”: Low NG, “H”: High NG
Example)
“LD”: Low torque NG and Double tightening detection NG
