Description
Version:
Robust torque wrench with impact resistant casing, 2-component handle, large display and reversible ratchet. Easy operation using large input buttons. Visual and acoustic signal indicates achievement of the set torque visually and audibly. Two working modes; selectable between peak value display and following display. The working memory can store up to 50 torque settings.
Units of measure: Nm, lbfft, lbfin, kgfm.
Units of measure: Nm, lbfft, lbfin, kgfm.
Sturdy plug-in ratchet with change-over wheel.
Application:
Torque control; controlled tightening of screws in a single operation or for small batch production.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
Clockwise ± 2 %, anticlockwise ± 3 %.
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.
