数显扭力扳手校准流程
Calibration process of digital display torque wrench
1、使用扭力扳手校验仪前，先检查仪器是否有点。如果电量不足事需要充电或者在充电的时候进行校准。
1. Before using the torque wrench to calibrate the instrument, check whether the instrument has any points. If the battery is insufficient, it needs to be charged or calibrated during charging.
2、将被测物的方形探头放入测试仪的方孔中，用被测物另一端的手柄在高度调节块上方（如果长度不够，可以整套自由调整装载装置）。
2. Put the square probe of the tested object into the square hole of the tester, and place the handle at the other end of the tested object above the height adjustment block (if the length is not enough, the loading device can be adjusted freely in a whole set).
3、打开电源开关，显示的扭矩值为零，如果不为零，按复位键复位扭矩值。
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。
4. Before the test, the upper and lower limit values, small storage values, small peak holding values, automatic peak time, automatic shutdown time, gravity acceleration, etc. shall be set.
①、上限设置：用户设置上限，根据需要自由设置，达到上自动声光提示，上限不高于满量程。
① Upper limit setting: the user can set the upper limit freely according to the needs. When the upper limit is reached, it will be automatically prompted by sound and light. The upper limit is not higher than the full scale.
②、下限设置：用户设置下限，可根据需要自由设置。当达到下，自动灯会提示。下限不得高于设定的上限。
② Lower limit setting: the user can set the lower limit freely as required. When the lower limit is reached, the automatic light will prompt. The lower limit shall not be higher than the set upper limit.
③、小存储值设置：用户根据存储需要设置小存储值，小于该值的数据将不被存储。
③ . small storage value setting: the user sets a small storage value according to storage needs. Data smaller than this value will not be stored.
④、小峰值保持值设置：用户需要根据峰值自由设置自动峰值测量，小于该值的数据不会被峰值保存。
④ Setting of small peak holding value: the user needs to freely set automatic peak measurement according to the peak value, and data smaller than this value will not be saved by the peak value.
⑤、自动测峰时间设置：用户可以根据自动测峰状态下峰值需要保持的时间，在1秒到99秒之间自由设置时间。
⑤ Automatic peak measurement time setting: the user can freely set the time between 1s and 99S according to the time that the peak needs to be maintained in the automatic peak measurement state.
⑥、自动关机时间设置：在无操作状态下，自动关机时间可以在0分钟到9分钟之间自由设置（设置为0分钟时，表示取消自动关机）。
⑥ Automatic shutdown time setting: under no operation state, the automatic shutdown time can be freely set between 0 minutes and 9 minutes (when set to 0 minutes, it means to cancel the automatic shutdown).
⑦、重力加速度设置：用户可以根据当地的位置设置重力加速度值。本机默认值为 9.794。
⑦ Gravity acceleration setting: the user can set the gravity acceleration value according to the local location. The default value of this machine is 9.794.
⑧、恢复初始设置：用户操作不当或多次更改数据后出现混乱，可通过此设置将1到7的数据恢复到出厂状态。
⑧ Restore the initial setting: if the user operates improperly or changes the data for many times, the data from 1 to 7 can be restored to the factory state through this setting.
