Test Methods Before conducting the determination of cement components, please carefully read the GBT12960-2019 standard for quantitative determination of cement components and prepare all the necessary reagents and equipment. 2. Place the instrument on a stable and level workbench. Before starting up, add an appropriate amount of water to the water tank first. The water level should be about 50mm above the bottom 4. Place it on the stainless steel beaker stand, close the lid, and then connect the power supply. 5. Set the water temperature to 20℃ and run it. 6. According to the test requirements, place the prepared samples into the water bath. Click to run the timer. When the timing is up, the device will beep to remind and stop running. 8. After the experiment is completed. When turning off the instrument, please turn off the power switch last and unplug the power cord. V. Precautions Before the equipment is put into operation, it is not necessary to add water first. To prevent damage to the heating accessories.
