How to test pressure for Compressive testing machine of concrete
Nov 20, 2017

(1)Put down the specimen according to the requirement of experiment, turning the screw pole until the upper platen don’t touch the specimen, turning on the machine and rising the oil cylinder, press 【CLEAR】 key to CLEAR the tare weight.

(2)When the gauge electrify or press 【PARAMETER】 key under measuring status to start experiment.

The gauge display:

P 0 0 0 1

S - - - 2

“P0001” indicating the number of specimen is 0001 (No.1 flashing)

“S---2”indicating the number of section of the specimen is 2 (NO.2 flashing)

Number of section 1,2,3,4,5,6,7,8,indicating:

     1 ----------- 100x100 cube specimen 

     2 ----------- 150x150 cube specimen(standard specimen)

3 ----------- 200x200 cube specimen

4 ----------- any section specimen

5 ----------- 150x150x550mm flexure specimen

6 ----------- 100x100x400mm flexure specimen

7 ----------- 40x40x160mm compression specimen

8 ----------- 70.7x70.7mm cube compression specimen

(3)Pressing corresponding number key, input 4 digital number, for example, input “0108”and press “enter”, then input the Section NO., 1 or 2,3,4,5,6,8, If customer input section No. is 4, he or she should input the real section value(mm2), if the section is 70.7x70.7mm, you should input “5000” and then press “enter” to start the experiment. Before the specimen being pressed, the group NO. and serial No. are display in the “speed panel” of the gauge. “108-1” indicating the group No. of this specimen is 0108 and the serial No. is 1.

(4)Turn on the outlet valve to load, gauge begin to display “force value” when it comes to 2KN. Controlling the outlet valve to load until the specimen break, turn on inlet valve, gauge will record the PEAK VALUE automatically and save in the memorizer, putting the second specimen of the same group, press 【CLEAR】 key to clear the former testing value, turn off inlet valve, controlling outlet valve to load until the specimen break, turn on inlet valve, gauge will record the PEAK VALUE automatically and save in the memorizer, putting the third specimen of the same group to make examination. After testing, gauge will print the result automatically if you have set it. (If customer choose section is 7, the result can be printed until the sixth specimen has been finished. If you want to end this examination in advance, you can press 【END】 key), meanwhile judge the data is valid or not, if yes calculate the average value, print the result and the gauge will go to next group examination of the same section.


Inquiry Operation:

Press 【INQUIRY】 key under measuring status, gauge display “P---”, input group NO., for example “P0020”then press “enter”, the gauge will display the breaking force value of the first specimen of this group examination, then press “enter” again, gauge display its’ breaking strength, press “enter” one more time, you can see the force value and breaking strength of other specimens of the same group examination, then press 【CANCEL】 key to escape.

Print Operation:

Press 【PRINT】 key under measuring status, gauge display “P0000-0000”,input group NO. then press “enter”.
