Hints
•
Use the torque table at the end of these instructions
•
The standard unit of measurement is the Newton-metre, symbol "Nm"
1 metre-kilo = 9.81 Nm
1 Nm = 0.102 metre-kilo
•
Never exceed the maximum torque of your wrench, taking special care when freeing tight nuts and during angular tightening.
•
Set the torque wrench to the minimum torque before putting it away in its box.
Maintenance of precision
•
We advise you to have your torque wrench checked regularly on a test rig or by the USAG metrological laboratory
or more often for intensive use or if dropped)
Precision checking and updating of reports:
•
The USAG metrological laboratory will draw up test reports or calibration certificates on request :
Test report: Testing and adjustment, if necessary, at 20, 60 and 100% of the torque wrench's capacity, within the tolerance: ± 4%.
A dated and numbered report is drawn up.
Calibration certificate Testing and adjustment of the torque wrench at 6 or 12 values, testing apparatus linked to the national
measuring standard.
A dated and numbered official document is drawn up.
For further information ; ask your dealer.
