Installation and Operation Instructions:

1. Pressure Setting: After power-on, press the "Set" button, then use the "Back" key to navigate. Press the "Shift" key (>) and adjust using "+" and "--" buttons. Save by pressing "Set" again. Exit after setting the lower limit value.

2. Pressure Peak Value: Long press for 3 seconds to enter settings. When the display shows "B", set it to 0 to maintain maximum pressure. You can also set any time unit in minutes, with a minimum of 0.1MPa.

3. Time Reset: To restart the experiment, hold the "--" button. After 10 seconds, the time will reset to 0 minutes. Be careful not to press "!" accidentally.

4. Time Review: Press the "--" key to switch to hour mode. The upper limit is minutes, and the lower limit is seconds. After 30 seconds, return to pressure display.

5. Time Setting: Long press and hold for 3 seconds to enter settings. When the time window shows "T", you can set the pressure increment time in minutes.

6. Zero Adjustment: If no pressure is detected after starting, and it doesn't return to zero, press the "Set" button once. Avoid pressing the "Clear" button when there is pressure; wait until it's released before resetting.

7. Water Injection: Open the water valve and add distilled water. Once the tank is full, start pressurizing and open the pressure control valve to allow water to flow into the high-pressure chamber until it overflows.

After completing the experiment, open the drain valve of the high-pressure tank and clean the instrument surface with anti-rust grease. If the equipment is not used for an extended period, make sure to drain all water from the system to prevent freezing and cracking.
