3. There is no vibration source and no corrosive environment around.


1. Before using the torque screwdriver tester, first check whether the power of the instrument is sufficient. If the power is insufficient, please charge it first (the instrument can also be used while charging).

2. Under normal circumstances, turn on the power switch, and the displayed value is zero. If it is not zero, press \"Clear Zero \" to clear the value.

3. Before testing, you need to set the upper and lower limits, minimum storage value, minimum peak hold value, automatic peak time, automatic shutdown time, gravity acceleration, etc. The specific steps are as follows:

a. Upper limit setting: The user sets the upper limit value, which can be set freely according to the needs. When the upper limit value is reached, an automatic audible and visual alarm is given, and the upper limit value is not higher than the full range. On the measurement interface, press \"Settings \" to enter the setting interface, select \"Upper Limit Setting \", press \"Settings \" to enter the \"Upper Limit Setting \" interface, press \"\"Key to change the value, press \"\"Key to change the number of digits, set the required value, press \" Save \"key to return to the setting interface, the lower limit setting is the same as above. (The upper and lower limit setting value is 10, the minimum is 0)

b. Setting of lower limit value: The user sets the lower limit value, which can be set freely according to the needs. When the lower limit value is reached, an automatic light alarm will be given. The lower limit value shall not be higher than the set upper limit value. The specific setting is as the upper limit setting.

c. Setting of minimum storage value: The user sets the minimum storage value according to storage needs, and data smaller than this value will not be saved by the peak value. Select \"Minimum stored value \", press \"Settings \" key to enter, also use \"\"Key and \"\"Key to set the required value, press \" save \"key to return to the setting interface (minimum stored value set the maximum value is 10, the minimum is 0).

d. Setting of the minimum peak hold value: The user needs to set freely according to the peak value and the automatic peak measurement. Data smaller than this value will not be saved by the peak value. Enter \"Minimum peak hold value \" interface, also use \"\"Key and \"\"Key to set the required value, press \" save \"key to return to the setting interface.

e. Automatic peak time setting: the user can freely set the time that the peak value needs to be maintained from 1 to 99 seconds according to the automatic peak measurement state. Enter \"Auto Peak Time \" interface, also use \"\"Key and \"\"Key to set the required value, press \" save \"key to return to the setting interface.

f. Automatic shutdown time setting: under no operation state, the automatic shutdown time can be freely set from 0 minutes to 9 minutes (when set to 0, it means that the automatic shutdown is released). Enter the \"Auto Shutdown Time \" interface, use \"\"Key to set the required value, press \" save \"key to return to the setting interface.

g. Gravity acceleration setting: The user can set the gravity acceleration value according to the location of the area, the default gravity acceleration value of this machine is 9.794). Enter \"Gravity acceleration \" interface, use \"\"Key and \"\"Key to set the required value, press \" save \"key to return to the setting interface.

h. Restore the initial settings: improper operation by the user or confusion when changing the data multiple times, you can use this setting to restore the data of 1 ~ 7 to the factory state. Enter the \"Initial Settings \" interface, and complete the setting after entering the password.
