Displaying accuracy: Displaying ** bit behind decimal: when choose “NIL” in the frame “Auto” under this item, this item will work to control the displaying bit number of load and stroke on the “display panel”. Auto: The displaying accuracy has strict and specific stipulation in the relevant test standards, so choose this item will identify the displaying bit number according to test load step automatically. Clock cycle: The amplifier will connect the computer and testing machine together as the hinge. The computer, as the data acquisition system, should record the test procedure real time and accurately. The sampling cycle is the test process “step length” recorded by the computer, which it should be better if shorter theoretically. The sampling cycle is shorter, the collected data will more during the unit time, the curve will be more actual, but the limited store point number (65000), so this will cause short store date time, please consider carefully and set this parameter correctly. For static test, we suggest adopting 60ms, and the effect is excellent attested practically. Change step: Setting if change step and the parameter of change step delay time (Generally 500ms or above), due to specific meaning, so no redundant statement

- 6 -


zero (general hardware zero-adjusting at chosen scale or Min. Scale) by hardware

zero button . If no method to up to zero, it can use software to make it zero by

software zero button. The hardware zero-adjusting only use for one time at chosen Min. Scalse, but the software zero-adjusting must be used at every scale after hardware make zero, and then to do test, otherwise it will have deviation for measured load value. Generally the software have adjusted the zero point of extensometers ready before going out the factory, when start every time, the system will calibrate the zero point of hardware automatically, no need for user to readjust. But if the zero point is very big due to some reasons, the user can adjust the zero point of the system as the method above mentioned. 3.2.2 Load measuring peak Load peak display: Display the load peak (Max. Load value) during test, this value cannot be cleared to zero, it need zero button to make zero. Click “up” and “down” can switch to display upper and lower peak value. 3.2.3 Load measuring scale: According to the big and small of the measuring value to switch automatically during the test, namely when the measuring value is bigger than 95% (parameter can be set) of measuring range of the current scale, it will change to bigger scale automatically; when the test start, the user can choose the Min. Scale so as to guarantee the accuracy. 2000N,1000N,400N,200N (different load cells will have various scales) buttons are used to control load amplifier to change scale. If click 2000N button, it denotes the measuring rang of testing machine is in full scale load cell capacity; if choose 1000N, it denotes the measuring rang of testing machine is 1/2 of full scale; the others are similar, namely the measuring range is 1/5 of full scale, 1/10 of full scale individually. The software can make the load range change both automatically and manually. But please consider below: 1. The operator is familiar with ordinary specimen. 2. Frequent changing steps will generate electric signal impact. So the default setting is “ No automatic switch scale”. Before test, the user should choose suitable scale according to test requirement or estimated Max. Load value. Generally the user should choose Min. Scale, but it should large than 20% of used value.

★ Remarks: Recommend changing load steps manually, so before test, the user should choose the load step of testing machine correctly which can enhance the test resolution.

3.2.4 Extension measuring display value Display the measured deformation of extensometer real time, and corresponding with the deformation of the test curve. If no special statement, the unit is mm. Before test, the user should adjust the extension to zero by upper and lower arrow buttons, if fails, please make it zero by zero button.

Remarks: It is similar to the load zero adjusting, please use the hardware zero adjusting button firstly.

3.2.5 Extension measuring scale: Remarks: Large deformation extensometer has not mentioned in this item. According to the big and small of the measuring value to switch automatically during the test, namely when the measuring value is bigger than 95% of measuring range of the current scale, it will change to bigger scale automatically; when the test start, the user can choose the Min. Scale so as to guarantee the accuracy. 10mm, 5mm, 2mm, 1mm buttons are used to control extension amplifier to change scale. If choose 10mm, it denotes the measuring rang of testing machine is in full scale; if choose 5mm, it denotes the measuring rang of testing machine is 1/2 of full scale; the others are similar, namely the measuring range is 1/5 of full scale, 1/10 of full scale. The software can make the extensometer measuring range changed both automatically and manually. When automatic switch measuring scale, it is generally from low scale to 1 scale directly. In order to enhance the measuring resolution as high as possible, before test the user should switch the measuring scale to 1mm scale directly. During test, this software can switch scales automatically according to request. Default status is “ No automatic changing step”. 3.2.6 “Take Down extensometer” button: This button has two using methods: 1. The extensometer is used in test: During test, when the extension of specimen is

small, extension measuring adopts measuring signal of extensometer, when the extension is big, in order to avoid destroying the extensometer, the extensometer must be dismantled, before dismantling, press this button, the system will use stroke measuring signal as extension value to guarantee the integrity of test curve;

2. No extensometer in test: If the user didn’t need extensometer during test, please press this button before test, so after test start, the system will take the stroke signal as extension value to form an integrated curve of load-extension which is convenient to data analysis.

Remarks: The extensometer is the measuring transducer used to measure specimen deformation with gauge length, so when you want to acquire test result connected

with deformation, please use the extensometer. Need the extensometer when measuring below test data (Please refer to GB228-2002 or ISO6892: 1998).

Various kinds of stipulated non-proportional extension strength, such as Rp0.1\0.2----- etc.

Various kinds of stipulated total extension strength, such as Rt0.1\0.5----- etc. The strain of special points, such as Max. Total extension rate Agt, elongation

of yielding points, etc. Because the extensometer is open type transducer, and the measuring range of which is always very small, so it is difficult to use it. Please use it on the basis of full understanding, and practice again and again up to skilled usage. Here offers some important information for your reference. (1) Zero-adjusting of the extensometer As the open type transducer, zero point has close relations with open value, so

when adjust zero the user should has the concept of “the open value of the extensometer influences zero point”, more careful especially when small measuring range.

The zero adjusting of the extensometer (extension channel) should happen after clamping the extensometer on the specimen and when the piston of testing machine is in the stop status. If the zero button cannot make it zero, please adjust the clamping position of the extensometer to make the extension measuring channel into adjustable zone.

(2) Installing the extensometer The initial clamping position of the extensometer should be on the initial gauge

length position. After the extensometer is installed on the specimen, please tap the edge area by

the hand to feel if it is tight. If has sliding phenomenon, it denotes the failure of installation, please reinstall.

The installing process should make along with the process (1) 3.2.7 buttons introduction ▼ Hardware adjust zero: Make the hardware zero point low ▲ Hardware adjust zero: Make the hardware zero point up

4. Brief introduction for test procedure 4.1 Specimen mounting First clamp the upper of specimen when mounting, and adjust the crosshead to suitable position through the buttons of “Up” and “Down” on the control panel, and clamping the extensometer on the specimen ( If no extensometer, please press the button of “ Take Down” on the display plate of load and deformation). After adjusting the zero point of load cell and deformation transducer, and then clamping the lower of the specimen. Remark: Firstly use hardware adjusting zero button to adjusting zero point, if can’t

adjust it to zero, use the software adjusting zero button when the value (load or deformation ) is the closest to zero.

4.2 In-put specimen information In-put the corresponding information according to the actual specimen. 4.3 Setting control modes and test speed, etc. According to actual specimen to choose suitable test control mode and speed to acquire the right test results. 4.4 Start test After setting parameters of the specimen, press the button of “ START” to start test. During control, please pay close attention to test process, and interfere by man if necessary. In the process of test control, it had better not make irrelevant operation to avoid effecting control. Before dismantle extensometer, the user must press the button of “ off extensometer” on deformation display panel, otherwise the deformation signal will be recorded actually when dismantle the extensometer, so it will effect subsequent data analysis.

Take parameter of load as an example: When calibrating, first choose corresponding scale, and adjust load up to zero, and then use proving ring or weights to calibrate, if 200N, please choose or input 200 in the choice frame of calibrating value, at the moment when standard weights or proving ring reaches the standard value, if indicating value is inaccurate, please press the button of “Calibrate”, thus the system will adjust gain automatically to make the indicating value accurate. After changing scale, click this window to reactivate automatically to make following calibration. After finishing calibrating for all scales, click button of “Ok” to store them into default system parameter files, thus the parameters can be entered automatically when the program runs once again. The operator had better store the file as the name of “system parameters when calibrating” using the menu of “store system parameter in main window for later checkup. After calibrating, please restore the operator authority.(No password) 5.2 System parameter setting (for executive user only). The window of system parameter setting is as shown as diagram 24. Remarks: Only system adjusting staff can modify these parameters, if parameters are wrongly set, the system cannot run properly.

Diagram 24. System parameter setting window Main parameters: the system is a kind of general test software, so it can meet application requests for testing machines with different capacities and configurations. The Max. Load and Max. Deformation tested by setting system are set according to specific test request, so they confirm the Max. Test range for this test. Displayed renew cycle is set as ordinary screen renew rate accepted by man, so no specific stipulation, so suggest to use recommended value. Amplifier: setting the parameters of AD card, setting magnification of load and extension of the first scale.

Stroke(Photoelectric encoder): setting relevant parameters of photoelectric encoder, Extensometer: not state more here due to simple. Signal channel: not state more here due to simple. 5.3 Adjusting (for executive user only) Includ hardware zero-adjusted, software calibration, software gain and PID parameter adjusting. Individual explanation is as follows. Hardware zero-adjusted: (Only adjusting staff can adjust, forbidden for customer)

Diagram 25. Hardware zero-adjusted

The amplifier section of PCI card adopts zero-adjusting digitally. Through

adjusting “move” bar, and observe the indicating value in the “display panel” to realize zero adjusting to corresponding channel amplifier. Control volume displays digital volume to make operation convenient for operator. Generally, the adjusting staff have adjusted the zero point ready, when start every, the system can calibrate the zero point of hardware, no need for customer to adjust. The user can adjust the zero point of hardware in the zero-point adjusting window, and the system will record new zero point adjusting value. Amplifer Adjusting: (Only adjusting staff can adjust, forbidden for customer)

Diagram 26. Software gain adjusting

Use standard load measuring device to calibrate load, through adjusting the “adjusting bar” of gain in the diagram 26 to make display value corresponding to the displaying value of standard device, and press “store” to finish operation. Do this to every scale, and calibrate repeatedly. Adjusting PID parameter: (only executive user for this function can adjust!) The adjusting procedure is P-I-D. First setting the parameter of I and D to zero or mini-value, enlarge P gradually, and carefully observe the response of testing machine. When P enlarging a certain value, the testing machine will self-excitation (it had better avoid self-excitation, through carefully observation, the omen of self-excitation is evident. It will destroy the machine if the self-excitation is too large or too small), and reduce it to 2/3. Sometimes the testing machine will have evident unstable and non-control status, this phenomenon is similar to self-excitation, this is caused by deficient adjusting value. Enlarging P value gradually, if the phenomenon disappears, it attests the method is correct.

- 28 -


Diagram 27. Adjusting PID parameter After adjusting P value, please do test for some time and observe test results. Generally the setting value and feedback have evident deviation. At the time, please enlarge I value gradually, and observe the testing machine and the change of test results, and generally the deviation will decrease evidently. Enlarge the I value further up to the testing machine emerging self-excitation or instability of display, please rapidly reduce I value to 2/3. I value will influence the test results most in the close-loop control parameters, so please adjustment will be slow. After adjusting I value, please adjust D value. D value has specific physical meaning, but the change is not evident when adjusting, the principle is same with that of P and I. But the wave shape will distort heavily, so under the circumstance of sensitive P and I adjusting, to enlarge D value will make a better effect. The adjustment of parameters of PID is supplementary each other, cannot be separate, also cannot adjust each other no direction and destination. At the appropriate time of adjustment, the parameters can adjust alternatively to require the best working status. The regulation of adjustment: (1) When the response of system is slow, please enlarge P value. (2) The stability of system is good, but the deviation is big, please enlarge I value. (3) The rapid system response cause the peak value over-adjusted, please reduce P

value. (4) When the system is instable, digital display has the phenomenon of self-excitation,

please reduce P and I value. (5) If the disturbing signal often emerges in the system, please reduce I value and

enlarge D value.
