Calibrating and adjusting torque wrenches
Calibrating and adjusting
torque wrenches
Only operate the calibration and adjustment
facility if all parts of the device are functional.
Make sure that nobody can be endangered before
introducing a torque.
Operating the hand wheel
The introduction of force into the calibration object
is carried out via the hand wheel at the front of the
device.
Unfold the hand wheel's handle.
To apply right-handed torque to the calibration
object, turn the hand wheel clockwise.
To apply left-handed torque to the calibration
object, turn the hand wheel counter-clockwise.
To relieve the calibration object, turn the hand
wheel in the relevant, opposite direction.
Fold up the hand wheel's handle following use.

Set-up mode
Turn the hand wheel so that the transducer is in
the neutral position as illustrated.
Testing and adjusting
Insert the torque wrench with the corresponding
calibration square or calibration adapter into the
transducer.
Select the calibration object to be adjusted in the
TORKMASTER 4 programme.
Start testing and adjusting mode in the
TORKMASTER 4 programme.
Set the desired adjustment value on the
calibration object and in the TORKMASTER 4
programme.
Set the longitudinal carriage so that the rest is
positioned centrally to the handle of the calibration
object.
Lock the longitudinal carriage with the lever.
Align the calibration object in the calibration and
adjustment facility according to the specifications
of the relevant standard.
Turn the hand wheel in the desired direction until
the desired torque is achieved.
