Calculating scale settings where an extension arm is used with the torque wrench
Each torque wrench has been specifically designed for a specific maximum scale reading and tested at this
level. For various reasons, it may be necessary in practice to add an extension arm.
To this end it is necessary to adjust the programming.
The required settings may be calculated using the following formula:
L1= Length of the lever arm on the torque wrench itself
B = Distance between the two pivot centres after attaching the extension
T = Tightening torque of the bolt
C = Setting value
Example:
L1 = 425 mm
B = 40 mm
C =
T = 20 Nm
C = ?
C = 18,28 Nm
B
For all assembly jobs, especially where access
with conventional sockets is not possible.
Right-hand turn for controlled screw tightening
(the torque wrench can also be used for controlled
left screw tightening, when turned over by 180°).
Accuracy is in accordance with
(7 Nm)
DIN/ISO 6789.1993, EN26789.1994.
