HOW TO APPLY TORQUE
1. This Electronic Torque Wrench is designed so that when force is properly applied to the hand grip, a continuous
audible signal, the LCD screen display and vibration in the handle will indicate that the Target Torque or Angle has
been attained. DO NOT pull beyond this point.
CAUTION: The audible signal, LCD screen display and vibration in the handle are indicators that the proper
torque or angle has been attained. Over torquing beyond these signals could cause fastener failure.
2. To properly apply torque, attach the socket securely on the torque wrench square drive and position the socket on
the fastener so that tilting will not occur. Grasp the center of the hand grip and apply a slow steady increasing force
perpendicular (90 degrees) to the torque wrench body and perpendicular (90 degrees) to the center line of the square
drive, socket and fastener.
3. Turn the fastener down with a smooth and even force applied to the handle of the torque wrench. As turning
resistance increases, pull more slowly. To assure accuracy, the fastener must be in motion when the torque
measurement is made.
WARNING: Any change from the above procedure will result in a change of torque being applied.
DO NOT USE universal joints or universal sockets due to the complexity of determining the associated error.
MAXIMUM CAPACITY EXCEEDED
1. When the applied torque exceeds the wrench full-scale capacity the LCD screen will show red and display “ovEr”.
2. Verify the calibration of the wrench if you know its capacity has been exceeded.
EXTENSIONS
1. When it is necessary to use an extension that changes the effective lever length of the torque wrench, torque being
applied will change.
Compute adjustments as follows: TW - Torque set on Wrench
TE - Torque applied by the extension to the fastener
2. Apply torque and rotate the wrench at a constant moderate speed until alerted to stop by the continuous audible
signal, the LCD Screen display and handle vibration.
Note: Socket extension bars that are axially in line with the square drive do not cause error and need no adjustment.
This torque wrench was calibrated prior to shipment from the factory within tolerance limits of:
•
Torque: +/- 2% Clockwise (Right handed) +/- 3% Counter Clockwise (Left Handed) from 20% to 100% of capacity
•
Angle: (+/- 1% of reading) + (+/- 1 degree @ angular velocity >10 degree/sec <180 degree/sec) + (+/- 1 degree of
test fixture)
TW = (TE x L) / (L + E)
TE = ((TW x (L + E)) / L
