Commissioning
Nothing shown on display If new, charged batteries are correctly
inserted and nothing appears on the
display after switching on by press-
ing and twice simultaneously,
the torque wrench with built-in angle
gauge is defective.
Send the torque wrench with built-in
angle gauge for inspection at your
HAZET Service Centre.
"System N.O.K." An electronic system test runs when
the unit is switched on. If the torque
wrench with built-in angle gauge is
under load when it is switched on, the
following message will appear
"System N.O.K."
Switch off the torque wrench with
built-in angle gauge by pressing
and simultaneously. Place the
torque wrench with built-in angle
gauge with no load on a smooth sta-
ble surface. To switch on the torque
wrench with built-in angle gauge,
press and simultaneously
again.
"System N.O.K." If you have checked that the torque
wrench with built-in angle gauge was
not subject to any load when it was
switched on and the "System N.O/K/"
still appears, the torque sensors are
not operating correctly, for example
after an overload.
Send the torque wrench with built-in
angle gauge for inspection at your
HAZET Service Centre.
"Service" If the message "Service" appears
when the torque wrench with built-
in angle gauge is switched on, this
indicates that 5000 load operations
have been performed since the last
calibration.
If you want to ignore this message,
confirmed by pressing and
simultaneously. Work can continue
immediately. This message will con-
tinue to be displayed every time the
device is switched on.
Send the torque wrench with built-in
angle gauge for calibration at your
HAZET Service Centre.
No value is shown on the display
when the torque wrench with built-in
angle gauge is in use.
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 for use.
Torque or rotation angle value alter-
nating with N.O.K.
The applied torque or rotation angle
value was not within the target value
tolerance. The torque or rotation angle
value was too low. No, or only the
first, signal level was activated during
operation.
Proceed according to the instructions
for such screwing incidents: for exam-
ple, loosen the screw and tighten it
again, or replace it with a new screw.
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 you remain within the
second signal level.
