Digial Torque Wrench -AWJ Model

User’s Manual for Digital Display Torque Wrench

1. Overview

1.1 Main purpose and applicable range

A ratchet-head digital display torque wrench are different from normal torque wrench, wherein the AWJC replaceable head wrench with its attached ratchet head can be replaced with an open head, a plum blossom head, a movable opening head,etc at any time. Both have powerful operating functions, including torque setting; unit setting; mode setting; value storage; value clearing; value output and user correction function. With easy operation, the digital display is installed to reduce the requirement on the operator. It is applicable to the fastening and control of bolts in automobile industry, machinery industry,etc.

3. Use method

3.1 Turn ON/FF by zero clearing: 

press C key to turn on, if the power value appears after the turn on, press C key to clear, under no operation, enter the sleeping mode for 5 minutes, press C key to start, and also press and hold C key to turn off.

3.2 Setting method of pre-set value: 

Under normal power-on state, shortly press M key on the measurement interface, and switch UP/DN key to obtain your required pre-set value. After setting the pre-set value, the system will automatically save the pre-set value, and continuously press M key until returning back to the measurement interface.

3.3 Setting methods of real time and peak modes: 

This product starts by real time mode T in default. If you want to switch to the peak mode P, you need to press M key twice shortly on the measurement interface, and pops up NODE, then you can select the T.P switching mode by UP/DN keys. After the selection is completed, press M continuously until returning back to the measurement interface.

3.4 Setting methods of unit mode: 

This product has totally four kinds of unit modes for selection such as N.m、in.lb、ft.lb、kgf.cm, which can be switched according to actual use condition. The modes are set up by press M key 3 times shortly on the measurement interface, and pops up UNLT, then the required unit modes can be selected by UP/DN keys. After the selection is completed, press M key continuously until returning back to the measurement interface.

3.5 Data save and checking method: 

The data save can be used under P peak mode, and the measured data can be discarded by directly pressing C key, and press OK key to save. After save is completed, you will automatically return back to the measurement interface for re-testing. By such circulation, max. data can be saved to 99 groups (data number is 001.002.....099 by sequence).

Data check. Press M key to check the saved data group on the measurement interface (display 0000 under no saved data) and data number can be checked by UP/DN keys, then if no operation lasts for 2 seconds, it will display the detailed force values saved by this number. After checking, press M key continuously until returning back to the measurement interface.

3.6 Clearing data storage values: 

Shortly press M key for 5 times on the measurement interface to pop up CLR, and press C key to pop up No?, then press C key again to confirm clear, which display DEL for completion, then returning back to the measurement interface. (If in No? Press M key on the interface to discard and delete, then returning back to the measurement interface. Note: Data clearing is one-time clear which completely clears all the data without single operation)

4. Precautions：

4.1 In order to maintain good accuracy, it is recommended to re-calibrate one time approximately every year.

4.2 Over-torque may cause damage or loss of accuracy (more than 105% of the maximum torque range).

4.3 Do not shake the wrench vigorously or drop the wrench to the ground.

4.4 Do not use the wrench as a hammer.

4.5 Do not place the wrench in a place with high temperature, high humidity or direct sunlight.
