1. Before using the torque wrench calibrator, check whether the power of the instrument is sufficient. If the power is insufficient, please charge it first (it can also be used when charging);

2、将被检物的四方测头插入检定仪的承力四方孔内，同时使得被检扳手另一端的手柄在高度调节块上方（若长度不够时，可自由调节整套加载装置）;

2. Insert the square probe of the inspected object into the bearing square hole of the calibrator, and make the handle at the other end of the inspected wrench above the height adjusting block (if the length is not enough, the whole set of loading device can be adjusted freely);

3、打开电源开关，显示的扭矩值为零，如果不为零，则按清零键，将扭矩值清零；

3. Turn on the power switch and the displayed torque value is zero. If it is not zero, press the reset key to reset the torque value;

4、测试前，需设置好上下限值、小存储值、小峰值保持值、自动峰值时间、自动关机时间、重力加速度等，具体操作步骤如下：

4. Before the test, the upper and lower limits, the minimum storage value, the minimum peak holding value, the automatic peak time, the automatic shutdown time, and the gravity acceleration should be set. The specific operation steps are as follows:

a)在用户主界面第1次按下“设置”键进入用户设置界面，通过向上键或者向下键进行设置项的选择，选择到用户的设置项时，按“设置”键进入参数设置界面，通过“▲”键和“▼键进行数据修改和移位，此时按“保存”健保存设置数据，显示屏界面返回用户设置界面，可进行下。一设置项（如按“置零”键则返回到进入用户设置界面，不保存修改数据)，当所有设置项都设置好并保存后，直接按“ON/OFF”键关机，再按“ON/OFF”键开机，进入用户主界面。设置的数据不能超过负荷值；

a) Press the "set" key for the first time in the user main interface to enter the user setting interface. Select the setting items by using the up or down keys. When the user's setting items are selected, press the "Settings" key to enter the parameter setting interface, and modify and shift the data through the "+" and "{keys. At this time, press the" save "key to save the setting data, and the display screen interface returns to the user settings Interface, can be carried out. A setting item (if you press the "zero" key, you will return to the user setting interface without saving the modified data). After all the settings are set and saved, press the "on / off" key to turn off the machine, and then press the "on / off" key to start the machine, and enter the user's main interface. The set data cannot exceed the maximum load value;

b)测试前，第二选择测量模式。在用户主界面显示为实时测量模式，当第1次按“峰值”键进入峰值测量模式，第2次按“峰值”键进入自动峰值测量模式，再（也就是第3次按“峰值”键时则返回实时测量模式，依次循环；

b) Before testing, the second choice is measurement mode. In the main user interface, the real-time measurement mode is displayed. When the "peak value" key is pressed for the first time to enter the peak value measurement mode, the second time the "peak value" key is pressed to enter the automatic peak value measurement mode, and then (that is, when the "peak value" key is pressed for the third time, it will return to the real-time measurement mode and cycle in turn;

c)测试前，第三选择测量单位。在任何测量模式第1次按“单位”键由显示为N/m单位进入到Kg/cm单位显示，第2次按“单位”键进入Ib/in单位显示：

c) Before testing, the third choice is the unit of measurement. In any measurement mode, press the "unit" key for the first time to enter the display from n / M unit to kg / cm unit, and the second time to enter Ib / in unit display

5、测试过程中，可按“保存”键将测量数据保存：

5. During the test, the measurement data can be saved by pressing the "save" key

6、测试过后，可按“查看”键查看已保存的数据，通过“▲”键和“▼”键显示上1条已保存数据或下1条已保存数据；

6. After the test, you can press the "view" key to view the saved data, and display the previous saved data or the next saved data through the "+" and "{" keys;

7、使用完毕，御下被检物后，按“ON/OFF”键关掉电源开关。

7. After using, press the "on / off" key to turn off the power switch after the inspected object is removed.

注意事项、保养及维修

Precautions, maintenance and repair

1、请勿超负荷测试扭矩，一定要在扭矩测试仪的测试范围内测试扭矩，

1. Do not overload test the torque, be sure to test the torque within the test range of the torque tester,

否则会损坏仪器，更有可能会造成危险。

Otherwise, the instrument will be damaged and more likely to cause danger.

2、请勿敲击液晶显示屏将物体放在液晶显示屏上。

2. Do not tap the LCD to place objects on the LCD.

3、请勿在水、油或其他液体溅到的地方使用扭矩测试仪，要将扭矩测试仪存放于阴凉、干燥和没有振动之处。

3. Do not use the torque tester where water, oil or other liquids are splashed. Store the torque tester in a cool, dry and vibration free place.

4、请勿松动扭矩测试头的固定螺丝。

4. Do not loosen the set screw of the torque test head.

5、使用配套的电源适配器充电，否则会引起电路故障，甚至引起火灾。

5. Use the matching power adapter to charge, otherwise it will cause circuit failure and even fire.
