Steps
1. Move the device to the designated position through the bottom PU activity wheel and fix the casters
2. Connect the 380V power supply and check the status of the equipment
3. Set the test parameters through the touch screen, and choose the program method or the setting method
4. Adjust the sample holder spacing and distribute the samples evenly on the sample holder
5. Start the equipment operation and monitor the test process through the observation window
6. After the test is completed, export the test data through the USB interface or SD card
7. Automatic shutdown and alarm when equipment malfunctions
Notice
• The load-bearing capacity of the sample should be evenly distributed, and the load-bearing capacity of each sample holder should be ≥ 20kg.
• Power supply voltage should be checked before operation
• Regularly check the automatic water replenishment device to ensure normal water supply
• Equipment failure should be dealt with in time after the alarm
• Install thermal insulation accessories and sealing soft plugs in time after the test hole is used
• The casters must be fixed after the equipment is moved
• Note that the rated current of the device is 18A and the rated power is 9kw when operating.
