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 a
level of expertise necessary in the field of controlled screw joint
tightening – and the quality of HAZET tools.
The HAZET factory also accepts electronic torque wrenches with
built-in angle gauge from your HAZET partner for inspection and
calibration.

Message
Nothing shown on display
Nothing shown on display
"System test not OK"
"System test not OK"
"Service"
The direction of rotation, the
torque target value and the
tolerance specification (in %)
are not displayed on switch-
on.
No value is displayed on
operating the torque wrench
with built-in angle gauge.
Design and function
Reason
No batteries inserted, batteries inserted incorrectly
or batteries are discharged
If new and fully charged batteries are inserted cor-
rectly and there is still nothing shown on the display
after switch-on by pressing
ously, the torque wrench with built-in angle gauge
is defective.
An electronic system test runs on power-on. If the
torque wrench with built-in angle gauge is under
load on switch-on, the message
"System test not OK" is displayed.
If it is certain that the torque wrench with built-
in angle gauge was not under any loading on
switch-on, and "System test not OK" is displayed
nevertheless, the torque sensors are not working
properly (e.g. following overloading).
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 per-
formed since the last calibration.
You are in mode "Torque track"
You are on the start display. "OK" is displayed.
10 . Torque Wrench with built-in angle
gauge certificate and calibration
instructions
Every torque wrench with built-in angle gauge comes with a qual-
ity 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 accessories is available for
