Repairing the torque and angle wrench
In the event of damage to the torque and angle
wrench or malfunctions, repair with subsequent
calibration is necessary.
Repairs may only be undertaken by the
Hoffmann Group.
Notes on calibration
Calibration or adjustment of the torque and angle
wrench may only be performed using a suitable
calibration device.
Torque and angle wrenches are test equipment.
The calibration interval is dependent on the
following operating factors, etc.:
Required accuracy
Frequency of use
Typical load during use
Environmental conditions during the working
process
Storage conditions.
The period of time for calibration arises from the
test equipment monitoring procedure defined within
your company (e.g. ISO 9000 ff). If test equipment
monitoring is not undertaken within your company,
have the torque and angle wrench calibrated or
adjusted after a maximum of 12 months starting
from initial use or after 5000 bolting processes
(DIN EN ISO 6789).
If the following is shown on the display after
switching on the torque and angle wrench, the
torque and angle wrench should be calibrated
according to the specifications of DIN EN ISO 6789
as soon as possible.
To continue working, acknowledge the message
with OK.
Have the torque and angle wrench calibrated
according to the specifications of
DIN EN ISO 6789 as soon as possible.
