Description
Version:
Knurled metal handle.
Function:
Actual torque can be read on the gauge whilst working; the final value is held by the memory pointer to be read later.
Application:
For controlled single tightening of screws and for controlled measurements.
Standard:
Tested to DIN EN ISO 6789.
Cutting data:
Legend for drawing and formula:
l1 = Lever length without plug-in head
l2 = Adjusted reference dimension on the torque wrench
l3 = Lever length including factory calibration reference dimension
l4 = Reference dimension of the plug-in head
L = Total length of the tool
T1 = Torque to be set
T2 = Specified torque
l1 = Lever length without plug-in head
l2 = Adjusted reference dimension on the torque wrench
l3 = Lever length including factory calibration reference dimension
l4 = Reference dimension of the plug-in head
L = Total length of the tool
T1 = Torque to be set
T2 = Specified torque
Note:
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
Warning:
Intended use
Reasonably foreseeable misuse
Intended use
Reasonably foreseeable misuse
- For controlled tightening of nuts and bolts.
