4.0 WRENCH CALIBRATION
Calibration is achieved using four Measuring Points, namely 10%, 20% , 60% and
100% of Maximum Span of the Wrench. In Calibration Mode the Wrench will
automatically display these Measuring Point Values initially for the Right Hand and
then for the Left Hand. All Products should be 1% accurate.
Calibration Mode is only accessible through the Master & Distributor Versions of the
PC Front End. The End User cannot access the Calibration Mode. Please ensure
that certified calibration systems such as a Norbar ISO 1000 Transducer system are
used when calibrating the Torque wrenches, These devices are themselves
accurate to 0.25%
Note : De-stressing wrench implies that the wrench is torqued to it's maximum span

Calibrate Mode
Note: Ensure date & time on wrench are correct
1. Connect wrench to PCFE software and Click the Activate Calibrate Button
2. Press MENU on the Wrench to scroll to Calibrate Mode. Place Wrench onto
Calibration Unit. De-stress on the CW (Clockwise) direction
3. Press OK to activate Calibrate Mode (The Wrench OLED will now display a
reading of 10% of the Maximum Span of the Wrench)
4. Apply Torque to the Wrench until the Reading on the Calibration Rig is equal to
the Reading on the Wrench (10% of Maximum Span)
5. Press OK to confirm that the First Point of Calibration is now set
6. Now Measurement Point No.2 (20% of Maximum Span) will appear on the
Wrench OLED Display. Therefore repeat Steps No.4 & No. 5
7. Now Measurement Point No.3 (60% of Maximum Span) will appear on the
Wrench OLED Display. Therefore repeat Steps No.4 & No. 5
8. Now Measurement Point No.4 (100% of Maximum Span) will appear on the
Wrench OLED Display. Therefore repeat Steps No.4 & No. 5
9. Repeat Step No's 1 to 8 for the Left Hand calibration
10. Once calibration is complete select Trac mode on wrench. On the Left hand side
check wrench accuracy at 20%, 60% and 100% according IS06789-2003. Now
De-stress on Right hand side and repeat step 10

This function will display the Torque that was applied after 3 degrees of movement,
It will also show the final Torque and angle that were applied by the user. The
screen will change to Red once the Just move Angle threshold is passed and the
Buzzer will sound. The user can set the Just move degree in the "Set" menu option
or using the PCFE software. The Final torque and final Angle that was achieved will
also be displayed as shown. The default Just Move Angle is 3 degrees.
1. Press MENU to Scroll to Just Mo ve Mode
2. Press OK to select Just Mode and then apply Torque and Angle
3. Press OK to store the 3 degree Torque Value and Final Torque and Angle value
If Storage is not required then apply New Torque and Angle measurement
Just Move Default to 3 degrees Just Move Measurement Just move result

Just Angle
This function will display the Peak Torque and Peak angle that were applied during
the Torque operation. The user can store the result at the end of each
measurement.
1. Press MENU to scroll to Just Angle and OK to select
2. Take a Torque and Angle reading
3. Press OK to store the result or apply another torque to continue
