angle, then press “SET”.
6. The wrench is ready to use.
7. Apply torque and rotate the wrench at a constant moderate speed until alerted to stop by the handle vibration, beeps
and LCD display.
8. To take the next measurement press “ ” or wait until the display stops flashing.
Note: After reaching the target angle the display will flash for 10 seconds, then default to the last setting. For
better accuracy the torque wrench should be rotated between 10 degrees/sec – 180 degrees/sec.

HOW TO CHANGE “TARGET TORQUE ALERT” AND “TARGET ANGLE ALERT”
PERCENTAGES
1. Power on the wrench as described on Page 3. Press “M” until the “PCt” mode is reached, then press “SET”.
2. The current value will flash on the screen.
3. Press “s” or “t” to select when the target torque alert will start. The target torque alert can start at a maximum of
50% to the target torque value or a minimum of 1% to the target torque value. For example, if your target torque is
100 ft-lbs and your target torque alert is set at 50%, the alert will start when you reach 50 ft-lbs. Press “SET” to save.
4. The screen will show “dEG” so the target angle alert can be adjusted.
5. Press “SET” to change the target angle alert setting. Press “s” or “t”to select when the target angle alert will start.
The target angle alert can start at a maximum of 50 degrees before the target angle or a minimum of 5 degrees before
the target angle. Press “SET” to save.
6. The wrench is ready to use.
HOW TO USE PRE-SET TORQUE VALUES
1. Power on the wrench as described on Page 3. Press “SET” then “M”. The setting number will show at the top of the
screen and the torque value will be flashing.
2. Press “s” or “t” to select the desired pre-set torque value and then press “SET”.
3. The wrench is ready to use.
HOW TO CHANGE PRE-SET TORQUE VALUES
Pre-Set Torque Values can only be selected in Peak or Peak Angle modes
1. Power on the wrench as described on Page 3. Press “SET” then “M”. The Pre-Set number will show at the top of the
screen and the torque value will be flashing.
2. Press “s” or “t” to select the desired pre-set torque value, then press for 3 seconds, after which the wrench will beep.
3. Now the pre-set number at the top of the screen will flash. Press “s” or “t” to select the desired torque setting, then
press “SET”. The new Pre-Set Value is saved into the Pre-Set options.
4. Press “SET” again to set the target torque to the new Pre-Set value.
HOW TO SET TORQUE WITH ANGLE
1. Power on the wrench as described on Page 3. Place the torque wrench on a stable flat surface to calibrate.
2. Press “M” until the “PA” mode is reached, then press “SET”.
3. The screen will show “OOOO” as the wrench calibrates, then will show last angle and torque value set.
4. If the desired angle and torque values are displayed, the wrench is ready to use.
5. If you want a different torque value or angle, press “SET” again.
6. To change the torque value press “s” or “t” to get to the required value, then press “SET”. The screen will show
“ANG”. If the target angle value previously displayed is correct, press “ ” to exit.
7. After setting the torque value, the screen will show “ANG”. Press “SET” to review or change the angle value.

LOW BATTERY
1. When the remaining battery capacity is at 30%, the battery icon on the display will flash. The Electronic Torque
Wrench will still function, but the battery will need to be replaced soon.
2. When the remaining battery capacity is at 10%, the battery icon will show continuously. The Electronic Torque
Wrench will not function correctly. Immediately replace the batteries.
CHANGING BATTERIES
1. Use AA (Alkaline) Batteries only.
2. Remove Batteries if the torque wrench is not used for an extended period of time.
3. Unscrew the end cap.
4. Insert two AA (Alkaline) Batteries (Positive end first).
5. Replace the end cap. The wrench will beep once if installed correctly.

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
