Design and function
8.12. Application / operation
of the torque
wrench with built-in angle gauge
The torque wrench with built-in angle gauge must only be ope-
rated with the handle at right angles to the screw joint. The hand
force deployed must be applied uniformly onto the centre of the
handle (ring marking).
In order to avoid measurement errors when measuring the rotation
angle, do not allow the screwed workpiece or its support to turn,
move or sway during operation.
You can also activate the dimmed display to reduce the power
consumption.
After approx. 30 seconds the display is dimmed slightly.
9 . Adjustment / calibration:
Electronic torque wrenches with built-in angle gauge should be
checked and calibrated on a regular basis. After a long period of
use, re-certification or re-calibration by the factory is advisable.
Electronic torque wrenches with built-in angle gauge are measu-
ring tools. Appropriate measurement equipment must be used
to test (and where applicable, adjust) measuring tools at the time
intervals laid down by Quality Management.
The time gap between test dates is dependent on the frequency
of use. We recommend testing after approx. 5000 screw opera-
tions (but the period in-between tests should be no longer than
6 months).
NOTE!
The “Version” menu option provides information
on the software version, the serial number, the date of
the last calibration and the remaining number of
releases until the next calibration of the wrench.

HAZET has appropriate test equipment. HAZET torque wrenches
with built-in angle gauge sent in to HAZET are returned with a test
certificate after they are checked and after any necessary adjust-
ment/calibration work is carried out. The test equipment used by
HAZET for torque wrenches with built-in angle gauge is continu-
ally monitored by the German Calibration Service (DKD) and is
calibrated and adjusted whenever required. This guarantees both
the level of expertise necessary in the field of controlled screw
joint tightening and also the quality of HAZET tools.
The HAZET factory also accepts electronic torque wrenches with
built-in angle gauge from your specialist dealer for inspection
and calibration.
10 . Torque wrench with built-in angle
gauge certificate and calibration
instructions
Every torque wrench with built-in angle gauge comes with a
quality test certificate in compliance with DIN 55350-18-4.2.2.
Please contact your HAZET partner if you lose the certificate or
require calibration instructions.
11 . Accessories:
A comprehensive range of quality accessori-
es is available for all HAZET torque/angle wrenches.
