V. Test procedure
1. Connect the air source first, then the power source. Turn on the [emergency stop switch] to power
up the instrument (if there is no alarm sound, the instrument is operating normally).
2. The instrument automatically enters the [Startup] interface. Check whether the boxes in front of
"parameter download completed" and "the pressure correction table is download " are marked with
"√", as shown in Figure 6-1. If yes, it means that the instrument parameter download is normal, and
you can proceed to the next step. Otherwise, follow the steps below to download parameters:
①.Click the "Enter the Test" button to enter the [Test] interface (as shown in Figure 6-2);
②.Click the "Help & Settings" button to enter the [Help & Settings] interface (as shown in Figure
6-3);
③.Click the "Parameter Setting" button to enter the [Parameter Setting] interface (as shown in
Figure 6-4). Set the loading pressure, vibration frequency and round-trip times
corresponding to each test stage. Click the "Data Download" button, and then click the
"Return" button to return to the [Help & Settings] interface;

- 11 -
④.Click the "Pressure Correction Table" button to enter the [Pressure Correction Table]
interface (as shown in Figure 6-9). Set seven groups of corresponding control voltage,
feedback voltage and actual pressure, and click the "data download" button;
WARNING!
In order to use this instrument safely and correctly, please carefully read the
precautions displayed on the [Startup] interface.
3. In the [Test] interface, click the "Loading and Unloading" button to enter the [Loading and
Unloading Settings] interface (as shown in Figure 6-3). Click the "loading position" button to make
the mold trolley move to the left side of the equipment to facilitate the loading and unloading of the
mold.
4. Turn off the power, open the protective door on the left side of the equipment, and remove the
fixed roller for the mold. Put the loaded test mold on the trolley of the roller compactor, put the test
mold fixed roller to fix the test mold, and close the protective door. For specific methods, please refer
to the "Feeding Steps" in the [Help notes] interface (as shown in Figure 6-11);
5. After the loading is completed, in the [Loading and Unloading Settings] interface, click the
"intermediate position" button to make the test trolley reach the middle position. After the test trolley
is in place, click the "preloading stage" button, and the instrument enters the preloading stage;
NOTE
In this mode, the vibrating motor does not work, but uses this stage to make
the pressurized cylinder and the round-trip cylinder enter the working state,
preparing for the formal start of the test.
6. In the [Test] interface, click any stage from "P1 stage" to "P6 stage". After selection, the word of
the selected button turns red, and the instrument can start working according to the parameters of
the selected test stage.
7. The instrument will automatically jump to the next stage after finishing the work of this stage. If
the number of round trips in the next stage is set to 0, the next stage will be automatically skipped
and the test will continue. After the instrument completes to the last test stage in sequence, it will
stop automatically. Click the button of the current stage, that is, click the button with the word in red
can stop the test in advance.
8. For example, click “P1 Stage” to start the test, the word of “P1 Stage” button will turn to red and

- 12 -
the instrument will start to run according to the parameters set in P1 Stage. After the P1 Stage is
completed, the instrument will skip to the P2 Stage automatically, the word of “P2 Stage” will turn to
red and the instrument will start to run according to the parameters set in P2 Stage. In this way, the
instrument will automatically stop after the six test stage completed.
If the number of round trips of the P2 Stage is set to 0, the instrument will automatically skip the P2
stage and proceed to the P3 stage after completing the P1 stage.
If the P2 stage is in progress, click the "P2 stage" button can stop the test.
9. After the test process is completed and the instrument stops, in the [Loading and Unloading
Settings] interface, click the "Loading Position" button, and the mold trolley will move to the left side
of the instrument to facilitate the loading and unloading of the test mold. For specific methods,
please refer to the " Unloading Steps" in the [Help Notes] interface (as shown in Figure 6-11);
10. Turn off the emergency stop switch and disconnect the power supply of the instrument. Open the
protective door on the left, take off the fixed roller of the mold, and remove the rolled mold.
