3. Use and operation

3.1 Measurement interface

a. The real-time measurement interface mainly displays the real-time torque and angle of the current test; if during the test, the data of the test point is recorded, and the current spring number and the number of repetitions are also displayed.

b. In the real-time measurement interface, you can switch the direction of spring rotation, measurement mode, number of measurement segments and units; after the switch, the system will save the corresponding settings.

c. Rotation direction switching: control the turntable to rotate left or right.

d. Switching of measurement mode: it is divided into torsion-angle and angle-torsion. The difference between these two modes is that the reference is different. Torsion-angle is to record the spring torque according to the corresponding angle; angle-torsion is to record the spring according to the corresponding torque Angle.

e. Number of measuring segments: According to the set number of measuring segments, test the corresponding spring test points. One segment is to find the angle or torque of the first test point.

Real-time spring measurement, depending on the type, and the selected angle (relative to absolute) mode. The setting value of its running measurement will also be different.

In the twist-angle mode, select the angle relative mode, then the reference angle of segment 1 to segment 5 needs to be increased, otherwise it will not work properly; if the angle absolute mode is selected, then the reference angle of segment 1 to segment 5 It is decreasing, otherwise it will not work properly.

3.2 System settings

System settings include spring parameter settings, operating parameters, time settings, and factory reset. As shown below:

3.2.1 Spring setting

a. Test number: The test number MAX can be set to \"32 \". After pressing \"Add \", the test number increases by one group, enter the required spring parameters, and press \"Save \". As shown below:

b. Number of repetitions: The number of repetitions MAX can be set to \"99 \". After pressing \"Add \", the test number increases by one group. Press \"SUP \" and \"SDN \", and the cursor moves to \" At the number of repetitions \, enter the required value and press \"Save \".

c. Running speed: The running speed during the spring test is expressed as mm / min. The larger the value, the faster the speed.

d. Angle (deg): the position of the spring test period.

e. Reference value: the force value corresponding to the segment point.

f. Tolerance: The setting for determining the qualified range of the spring can be set from \"0% \" to \"99% \". For example, when set to \"1% \", the upper limit value is and the lower limit value is. During the spring test, if the force value is within the upper and lower limits, it is qualified.

After setting the spring parameters, press \"Save \". Users can also switch \"selected number \" to choose different spring settings.

3.2.2 Operating parameters

a. Acceleration and deceleration setting: acceleration and deceleration setting refers to the acceleration setting of the rotary table during measurement. When set to \"0 \", it is turned off; when set to \"1 \", it is turned on. The acceleration setting and the measurement point stop setting are in conflict. Only when the measurement point stop setting is set to \"0 \", the acceleration / deceleration setting is valid.

b. Measurement point stop setting: The measurement point stop setting refers to the stop setting of the instrument at each segment point during measurement. When it is set to \"0 \", it is turned off; when set to \"1 \", it is turned on. status. In the open state, if the segment number is set to \"5 \", the instrument will stop once at these five segment points during measurement; if it is off, the instrument will not stop at the segment point during measurement.

c. Continuous test setting: Repeat the test setting. When set to \"0 \", it is turned off; when set to \"1 \", it is turned on.

d. Starting speed: The starting speed setting is only valid when the acceleration / deceleration setting is turned on. The starting speed can be set from \"1 \" to \"5 \". When set to \"1 \", that is, the acceleration from 1mm / min to 100mm / min during measurement, the greater the value setting, the faster the acceleration start speed. The speed setting unit is mm / min, and the starting speed cannot be set to \"0 \".

e. Excluding the stiffness of the first segment: When the stiffness of the first segment is set to \"1 \", it is turned on. For example, when 5 segments are set, the instrument will not calculate the stiffness of the first segment when calculating the average stiffness. If it becomes \"0 \", it is closed.

f. Sampling rate: the sampling times of the instrument per second, which can be set from \"1 \" to \"100 \".

g. Automatic zero speed:High-speed setting of automatic origin, the unit is \"mm / min \". When the automatic origin button is pressed during measurement, the spring will return to a position relatively close to the origin with the set automatic zero high-speed value.

h. Automatic zero low speed:Auto zero low speed is a value set on the basis of auto zero high speed, the unit is \"mm / min\". When the spring returns to a position relatively close to the origin, the automatic zero point starts at a low speed at this time, so that the spring returns to the origin position more accurately.

i,Zero point high ratio / zero point low ratio: These two parameters are the force value determination of the automatic origin. The ratio of zero point height is \"200 \", that is, the force value is full scale * 200/10000, which is 2% of full scale. The low ratio of zero point is \"3 \", that is, the force value is full scale * 3/10000, which is 0.03% of full scale. After starting the automatic origin, when the force value is close to 2% of the full scale, the instrument will stop at the position of the automatic origin according to the low percentage of the force value after the force value pauses for a few seconds.

j. Angle absolute mode: when set to \"1 \", it is angle absolute mode; when set to \"0 \", it is relative displacement mode. For relative measurement mode and absolute measurement mode is the difference between the set angle. The relative measurement mode is how much the angle is rotated, and the absolute measurement mode is expressed as how much the angle is rotated.

Relative measurement mode, the angle required to set the number of spring segments, ANGLE1 < ANGLE2 < ... < ANGLE5

At the same time, torque setting is also required, TORQUE1 < TORQUE2 < ... < TORQUE5

The absolute measurement mode will have different setting parameters for different spring types

ANGLE1 > ANGLE2 > ... > ANGLE5
