Description
Version:
Handy and very compact single-arm torque wrench, adjustable by scale and self-triggering. Extremely high repeat accuracy, since high quality materials are used throughout. Wearing parts, such as compression springs, are specially pre-treated and sorted. Reversible ratchet for left-hand and right-hand tightening.
Acoustic and perceptible “click effect” ensures particularly easy use and accurate setting of the desired torque.
With built-in reversible ratchet with ejector − for left-hand and right-hand tightening.
Units of measure: Nm

With built-in reversible ratchet with ejector − for left-hand and right-hand tightening.
Units of measure: Nm
Function:
The wrench triggers giving a “signal” (clearly audible acoustic tone and noticeable vibration) and afterwards is immediately ready for use again.
Application:
For medium to larger batch productions.
Standard:
Tested to DIN EN ISO 6789.
Accuracy:
Of the displayed value only for right-hand tightening: ±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

T1 = Torque to be set
T2 = Specified torque
Note:
Calibration is only possible for right-hand tightening.
The guaranteed measuring accuracy of the torque is achieved only once the torque range has been calibrated to DIN EN ISO 6789.
