Install Batteries
1. Unscrew metal end cap and install (4) high quality AA batteries in handle.
Notes: When batteries are low a “BATT” icon will light. When batteries are
critically low the wrench will not turn on.
It is OK to use externally rechargeable batteries. Battery life depends on battery
quality and the amount the lights and buzzer are used (target torque).
Keep the end cap threads clean and dry for a good contact.
Power On
1. Press and hold the power button to turn the wrench on.
Notes: If you do not use the wrench for 3 minutes the wrench will automatically
shut off.
Do not apply torque to the drive when you power up.
If the wrench comes on and then shuts off immediately the batteries are
probably low.
All previously stored settings (units, pre-set target value, target %) are stored
even when the power is off and the batteries are out of the wrench.

View/Change the Pre-set Torque Value:
1. Press either target key once to see the current target value without making
any changes. The target will show for 3 seconds.
2. Press and hold the Target - button to lower the current target value. Press
and hold the Target + button to increase the current target value. The
longer you press and hold the target key the faster the display will change.
When you apply torque with a target set:
As you get close to the target torque value you will see a yellow light
warning you that you are approaching the target value.
When you are within 2% of the target value you will see a green light and
hear a buzzer. Stop pulling!
When you go over 2% of the target value you will see a red light and hear
an intermittent buzzer. Too much torque!
Changing Units:
1. Press the Units button to select different torque units: ft.lb.......In.lb.......Nm
Notes: When you change units the target setting will also be changed to the
new units value (makes a great torque conversion calculator).
The units selected will become the default units when the wrench is turned off
and on again.
Changing from Peak to Track mode:
1. Press and hold the “Power Clear” button when the wrench is on.
2. Press the “Target - ” button to change mode from Peak to Track while you
hold the power/clear button.
Press & hold to decrease
pre-set torque.
Press & hold to increase
pre-set torque.
Press to change units
Press & hold Power & Clear
Press Target - to change modes

Changing Tolerance Settings:
1. The default setting is +/- 2% of pre-set torque. The operator can adjust the
the setting from 1 - 10% or turn it off.
2. With the wrench ON, hold the power button and press the “Target +” key.
Keep pressing the “Target +” key until you show the desired value.
3. The tolerance setting provides a visual and sound signal if the torque
Passed or Failed.
- If the torque is under the pre-set torque & tolerance setting - Yellow light
- If the torque is within the pre-set torque & tolerance setting - Green light
- If the torque is over the pre-set torque & tolerance setting - Red light
Applying Torque:
1. Tighten nut or bolt by applying a steady even pull using built in ratchet as
necessary. Wrench should be kept at 90 degrees to axis of bolt during
tightening.
2. When pre-set torque is reached, there are 3 ways to determine what torque
is being applied:
- Look directly at the LCD.
- Pre-set torque and look for the lights.
- Pre-set torque and listen for the buzzer.
3. Once pre-set torque is achieved, do not apply any more torque or you will
over tighten it.
LCD Contrast:
1. The operator can change the LCD contrast (viewing angle) by first pressing
and holding the Units button and then press the “Target +” button. This is
useful when the temperature is very cold or very hot.
Notes: The contrast changes very slowly, so be patient.
Press & hold to Power Clear

Testing & Servicing
For testing the torque wrench either use a torque analyzer or
torque transducer within the range of the torque wrench. Make
sure you apply the torque slowly and smoothly.
In order to maintain accuracy, it is crucial that torque control
measuring equipment be calibrated regularly.
We recommend a general once a year calibration interval.
However, it is the user’s organization that must determine suitable
intervals based upon equipment performance, application, degree
of usage and management objectives.
For calibration, re-adjustment or repairs, please send the tool to
one of our 3 service locations.
Accuracy +/- 2% of reading, +/- 1 digit
Designed for daily screw tightening production environment.
Program pre-set torque.
Rotating head allows viewing of the display from any angle.
Three units of torque measurement available: N.m, lbf.ft, lbf.in
Selection of two operating modes: Track and Peak.
Heavy duty ratchet head or interchangeable end fittings
Go/No Go LED’s and a buzzer can be set for a high or low torque limits.
Four-digit display.
Battery operation (Optional - rechargeable battery adapter kit)
Optional RS-232 serial interface to download torque readings to a PC or
printer.
