correct operation, the accuracy of your torque wrench
with built-in angle gauge is crucial in order to guarantee
both quality and safety. The accuracy of the tool can only
be guaranteed by regular inspection or calibration, and, if
necessary, readjustment.
• We recommend - as per the DIN EN ISO 6789:2017 stan-
dard - inspecting and calibrating your torque wrench with
built-in angle gauge after one year at the latest or after 5000
load cycles. The inspection intervals must be shortened
in case of increased quality and safety requirements or
intensive use.
• To check the torque values simply and quickly, the 7900 E
series HAZET torque testers are available to you in three
sizes/torque ranges.
• To adjust and/or calibrate these, please send your HAZET
torque wrench with built-in angle gauge to the HAZET
service centre. You can ship it to us directly or via your
specialist dealer. With a DAkkS calibration at HAZET, we
offer you, as the user, security regarding the reliability of
