product description

I. Overview

1.1 Main uses and scope of application

The AWJC interchangeable head digital display wrench is different from the general torque wrench. The AWJC interchangeable head wrench has its own ratchet head that can be replaced with an open head, plum head, movable open head and other plug-ins. It has powerful operating functions, including torque Setting; unit setting; mode setting; value storage; value clearing; value output and user calibration function. It is easy to operate, and the requirement for the operator is reduced by installing a digital display. It is suitable for bolt tightening and control in automobile industry and machinery industry.

3. How to use

3.1,Zero switchPress the C button to boot, if there is a force value after the boot, you can press the C button to clear it, enter the sleep mode for 5 minutes without operation, press the C button to start, and also choose to press the C button to shut down.

3.2,Preset value setting methodUnder normal power-on state, short press the M key on the measurement interface, and use the up and down keys to switch the preset value you need. After setting the preset value, the system will automatically save the preset value. Press the M key continuously until you return to the measurement interface.

3.3Real-time and peak mode setting methodThe default real-time mode T of this product is turned on. If you want to switch the peak mode P, you need to press the M key twice in the measurement interface, NODE appears, and then you can choose the TP switching mode through the up and down keys. After the selection is completed, press the M key continuously until you return to the measurement interface That's it.

3.4,Unit mode setting methodThis product has four unit mode options: N.m,,,, which can be switched according to the actual use. Setting mode Short press M key three times in the measurement interfaceWhen UNLT appears, you can use the up and down keys to select the unit mode you need. After the selection is complete, press the M key continuously until you return to the measurement interface.

3.5,Data storage and viewing methodData saving. In the P peak mode, the measured data can be saved directly by pressing the C key. Press the OK key to save. After saving, it will automatically return to the measurement interface to test again. In this cycle, the data can be saved in 99 groups The numbers are 001.002 ..... 099).

View data. Short press M key 4 on the measurement interface to view the saved data group (display 0000 when there is no data saved). You can view the data number by pressing the up and down keys. No detailed display of the force value stored by the number is displayed in two seconds. Then press the M key continuously until you return to the measurement interface.

3.6,Clear data storage valueShort press M key 5 on the measurement interface, CLR appears, then press C key to display NO? Then press C key to confirm and clear, and display DEL to return to the measurement interface directly after completion (If you press the M key on the NO? Interface, you will give up deleting and return to the measurement interface. Note: Clearing the data is done all at once, so there is no single operation)

Four, matters needing attention:

4.1 In order to maintain good accuracy, it is recommended to recalibrate once every year.

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

4.3. Do not shake the wrench violently or drop the wrench on the ground.

4.4 Do not use the wrench as a hammer.

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

4.6 Do not use wrenches near water.

4.11, do not press the LCD screen heavily.

Five, battery handling

5.1. If the torque wrench is not used for a long time, please remove the battery.

5.2. When you need to travel long distances or in cold areas, please prepare spare batteries.

5.3 Do not mix batteries of different brands or mix old and new batteries.

5.4 Sweat, oil stains, etc. will hinder the contact of the battery electrodes. Please wipe the battery clean before putting in the torque wrench.

5.5. Please discard the used batteries in the designated recycling place. Do not put the battery into fire.
