• The second signal level – green flashing light, acoustic sig-
nal 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.
• The third signal level – red flashing light, acoustic signal
and high-frequency vibration – indicates that the applied
torque is above the target value range. If the third signal
level is reached, the applied torque is too high. Stop the
screw action. Proceed in line with the instructions for this
screw action: e.g. undo the screw and re-tighten it, or
replace it with a new one.
• The fourth signal level – red permanent light, permanent
acoustic signal and permanent vibration – indicates that
the applied torque is above the maximum permissible
torque range of the torque wrench with built-in angle
gauge. If the fourth signal level is reached, the screw action
must be aborted immediately. Failure to do so can result
in (irreparable) damage to the torque wrench with built-in
angle gauge.
• If no further torque or rotation angle is applied after activa-
tion, the display alternates between the maximum value of
this action and an OK/Not OK message.
• The "Torque track" programme displays the torque cur-
rently being applied without specification of a target value
or a tolerance on the display. In this program, only the
fourth signal level is activated when the maximum permit-
ted torque value has been reached. The highest torque
value for this process (without validation) is displayed when
no more force is being applied.
• The torque wrench with built-in angle gauge can be pro-
grammed with "Direction of rotation: left (+)" and "Direction
of rotation: right (-)" in the "Torque peak" and "Rotation
angle" programmes.
NOTICE! In "Torque track" and "Peak" mode, the screw
action stops after 2 seconds if no torque is applied dur-
ing this time. In "Rotation angle" mode, the screw
action stops after 4 seconds if no torque is applied
during this time.
• Every screw action is stored in the memory with a corre-
sponding date and time.
• Pressing a key rotates the display (in order to read the
display regardless of direction of operation).
• If it is not being used, the torque wrench with built-in angle
gauge switches off after 5 minutes for the basic version
and after the set stand-by time for the TOP version.
TOP version only:
• If necessary, a rotation angle check for torque tightening
and a torque check for rotation angle tightening can be prog
rammed in order to check the screw action and connection.
If a check function is programmed, the second signal level
is only activated and the screw action is only evaluated as
OK if the relevant target value and check ranges overlap
with one another at the end of operation.
• The "Parameters" menu option allows you to store pro-

Design and function
grammes for various screw actions. Activating a workflow
enables these screw actions (parameters) to be completed
one after another. The wrench display indicates the pro-
gress of the workflow.
