Two,Plasticity Testing MachineOperation
4.1Temperature Controller Operation
Temperature settings: Press the button at the bottom left to enter the temperature setting mode, navigate using "▼"▲Modify the numerical size, set to70Then press the button in the lower left corner to exit the setup state and enter control mode.
4.2Timer Operation
Panels display the real-time running time by default; pressRSTKey Reset to Zero. Press “SETPress the "<<" shift key to modify the running time, at this point, the number is displayed.1HzThe frequency is blinking, indicating that this position can be modified; press “∧” to adjust the time size; after modification, pressSETTap to enter the interval stop time modification; the method is the same as the runtime modification method.
4.3、Plasticity Testing MachineTesting Method
The required temperature for the test is:70°C, each sample's testing time is3Minute. Press “POWERPower on and press the "Reset - Timer" button to enter reset mode, which is the non-operational state.
First, set the temperature and time on the temperature controller and timer. After preparing three specimens, wait for the temperature to stabilize. During this time, measure the height of the specimens with a thickness gauge.0.01mmPlease note the data at this moment.h0。
After the temperature reaches, place a sample on top of the pressure hammer inside the incubator (without applying pressure) and preheat for three minutes, then close the door and press the "Reset - Timer" button simultaneously. The key pops up to enter the timing mode; an alarm sounds when the time is up, and the door is opened to retrieve the sample. After removal, place the sample in the pressure hammer room, turn the handle to drop the hammer for pressure application, while positioning the sample above the hammer for preheating. Close the door and start the timer; upon reaching the time, an automatic alarm sounds, and the "Timing Display" light illuminates.
Complete three specimens following the above testing method. After each specimen is completed, read the change in height from the percentage gauge on the instrument.h1Remove and wait for three minutes to cool before measuring the height with a thickness gauge.h2。
