9. Setting key: The user can enter the setting menu through this key on the measurement interface, and press this key to save the data when setting the data.

Seven: User operation instructions

1. Startup display

Startup display welcome and manufacturer information

Display product name, model and version information

2. User main interface display

3. User setting interface

Press the setting key once, as shown below:

Use the up or down arrow to select the setting item. When the setting item is selected to the user, press the setting key to enter the parameter setting interface.

4.Parameter setting interface

In the user setting interface, press the setting key to enter the parameter setting interface, which is displayed as follows:

Setting parameter description: (Taking the maximum torque value as an example)

Use the up and down keys to shift and modify the data. At this time, press the set key to confirm and save the set data (such as pressing the zero key to return without modifying the data). The set data cannot exceed the maximum load value.

(1) Maximum torque value: The user sets the torque upper limit value, which can be set freely as required. When the upper limit value is reached, the number above the parameter name \"torque upper limit value \" flashes, and the buzzer alarms. The upper limit is not higher than full scale.

(2) Minimum torque value: The user sets the torque lower limit value, which can be set freely as required. When the lower limit value is reached, the number above the parameter name \"torque lower limit value \" flashes. The lower limit cannot be higher than the set upper limit.

(3) Setting the minimum storage value: The user sets the minimum storage value according to the storage needs, and data less than this value will not be stored.

(4) Minimum peak hold value setting: The user needs to set freely according to the peak value and the automatic peak measurement. Data smaller than this value is not saved by the peak value.

(5) Maximum deformation angle setting: The user can set the maximum value of the angle, which can be set freely as required. When the upper limit is reached, the number above the parameter name \"Angle Max \" blinks.

(6) Minimum deformation angle setting: The minimum angle can be set by the user, and can be set freely as required.

(7) Automatic peak time setting: The user can freely set the time that the peak value needs to be held from 1 second to 99 seconds according to the automatic peak measurement state.

(8) Automatic shutdown time setting: In the non-operation state, the automatic shutdown time can be freely set from 1 minute to 99 minutes.

(9) Gravity acceleration setting: The user can set the gravity acceleration value according to the location of the area. The default value of this machine is 9.794.
