Nothing shown on display
If a new, charged battery is correctly inserted
and nothing appears on the display after
switching on by pressing (3 sec. until
acoustic signal sounds twice), the torque
wrench with built-in angle gauge is defective.
Send the torque wrench with built-in angle gauge to
your HAZET partner for testing.
"System test not OK"
An electronic system test runs at power-
on. If the torque wrench with built-in angle
gauge is under load when switched on, the
message
"System test not OK" is displayed.
Switch the torque wrench with built-in angle gauge
off by pressing . Place the torque wrench with
built-in angle gauge on a flat, stable surface such that
no loading is applied to it. To switch on the torque
wrench with built-in angle gauge, re-press (3 sec.
until acoustic signal sounds twice).
"System test not OK"
If it is certain that the torque wrench with
built-in angle gauge was not under any load
when switched on, and "System test not
OK" is displayed nevertheless, the torque
sensors are not working properly (e.g. fol-
lowing overloading).
Send the torque wrench with built-in angle gauge to
your HAZET partner for testing.
"Service"
If "Service" is displayed after switching on the
torque wrench with built-in angle gauge, this
is an indication that 5000 load cycles have
been performed since the last calibration.
If you wish to ignore this message, press and
at the same time. Work can continue immediately. This
message continues to be displayed every time the
device is switched on.
Send the torque wrench with built-in angle gauge to
your HAZET partner for calibration.
The direction of rotation, the
torque target value and the
tolerance specification (in %)
are not displayed when swit-
ched on.
You are in mode "Track torque"
You are able to work in program "Track torque".
You are able to change the torque program. Refer to
Section 8, Programming
No value is displayed
upon operating the
torque/angle wrench.
You are on the start display. "OK" is
displayed.
Check the settings carefully. Confirm the
settings by pressing . "OK" is no longer
displayed. The torque wrench with built-in
angle gauge is ready to use.
Torque or rotation angle value
not OK (alternately)
The torque or rotation angle value applied
was not within the programed tolerance of
the target value. The torque or rotation angle
value was too low. No, or only the first, signal
level was activated during operation.
Proceed in line with the instructions for this screw-joint:
e.g. undo the screw and re-tighten it, or replace it with
a new one.
Carefully increase the torque. Pay attention to the
actuation speed and the signal levels. Operate the
torque wrench with built-in angle gauge in such a way
that it remains in the 2nd signal level.
Torque or rotation angle value
not OK (alternately)
The torque or rotation angle value applied
was not within the programed tolerance of
the target value. The torque or rotation angle
value was too high. The 3rd or 4th signal level
was activated during operation.
Proceed in line with the instructions for this screw-joint:
e.g. undo the screw and re-tighten it, or replace it with
a new one.
Reduce the actuating force. Pay attention to the actu-
ation speed and the signal levels. Operate the torque
wrench with built-in angle gauge in such a way that it
remains in the 2nd signal level.
