2 . Included in delivery:
• TTorque wrench with built-in angle gauge with operating
instructions, examination certificate, rechargeable Li ion
battery, USB 3.1 A-C cable and insert reversible ratchets
per the table above, in the case.
3 . Function / signal levels
• The torque wrench with built-in angle gauge has four signal
levels (combined visual, audible and physical signals) that are
activated when configured values are reached.
• The visible signals are shown below the matted ring on the
handle, the audible signals are generated by a buzzer in the
housing and the physical signals are created by a vibration
motor in the handle.
• The torque wrench with built-in angle gauge has two
selectable operating modes: „Torque" and „Rotation angle".
• In „Torque" mode, you can select the torque programs
„Torque track" and „Torque peak".
• A snug torque (starting point for the angle measurement), a
target value for the rotation angle and a ± tolerance for the
rotation angle in „°" (degrees) are entered in the "Rotation
angle" program.
• A yellow light flashes once upon reaching the snug torque

and therefore the start of angle measurement.
• The first signal level – yellow flashing light, acoustic signal
and low-frequency vibration – starts when the applied
torque reaches the set threshold value, e.g. 80% of the
lower value of the target value range. Once the first signal
level is reached, you should reduce the tightening speed
and pay closer attention to the force you are applying, the
display and the signals of the torque wrench with built-in
angle gauge. The lower the target value and the higher
the threshold, the quicker the first signal level is exceeded.
• The second signal level – green flashing light, acoustic
signal and mid-frequency vibration – indicates that the
applied torque is within the target value range. Once the
second signal level is reached, stop screw action in this
area. The lower the target value and the tolerance value, the
quicker the second signal level is exceeded.
