**Shanghai Xinzhuang Water Bath Thermostatic Shaker Operating Instructions**
1. Place the test bottles into the shaker and ensure they are evenly balanced. If using a dual-function model, select the appropriate shaking mode based on your experiment requirements.
2. Turn on the power supply and set the timer according to the scale marked on the machine. For extended operations, adjust the timer to the "normally open" position to allow continuous operation.
3. Activate the constant temperature function:
(1) Move the control switch to the "Set" position. At this point, the temperature displayed on the screen represents the set temperature. Adjust the knob to the desired working temperature. **Note**: The set temperature must be higher than the ambient temperature for the system to start heating. When heating begins, the yellow indicator light will turn on; otherwise, the unit will not operate.
(2) Switch the control knob to the "Measure" position. Now, the display shows the actual temperature inside the chamber. As the internal temperature changes, the reading on the screen will update accordingly.
(3) Once the set temperature is reached, the heater will automatically shut off, and the green indicator light will illuminate. If the temperature in the chamber drops below the set value, the heating cycle will restart automatically, maintaining stable conditions throughout the process.
4. Start the shaking mechanism:
(1) Press the shaking switch on the control panel. The corresponding indicator light should turn on, confirming that the shaking function is active.
(2) Adjust the speed knob to the desired shaking frequency, ensuring it meets the requirements of your experiment.
5. After completing the operation, turn off the power. Return both the speed control and temperature control knobs to their lowest positions to ensure safe shutdown.
6. Clean the equipment thoroughly after use to maintain its performance and longevity.
