**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.
2. Turn on the power supply and set the timer according to the scale marked on the machine. For extended operation, switch the timer to the "normally open" position to allow continuous running.
3. Activate the temperature control system:
(1) Move the small control switch to the "set" position. At this point, the temperature displayed on the screen is the target temperature. Adjust the knob to the desired working temperature. Make sure the set temperature is higher than the ambient temperature to activate heating. When heating starts, the yellow indicator light will turn on; otherwise, the device will not function properly.
(2) Switch the control knob to the "measurement" position. Now, the display shows the actual temperature inside the chamber. As the internal temperature changes, the reading will update accordingly.
(3) Once the set temperature is reached, the heater will automatically stop, and the green indicator light will illuminate. If the temperature drops below the set value, the heating cycle will restart automatically.
4. Start the shaking function:
(1) Press the shaking switch on the control panel. The corresponding indicator light will turn on.
(2) Adjust the speed control knob to the desired shaking frequency.
5. After completing your experiment, turn off the power. Return both the speed and temperature control knobs to their lowest positions for safety and maintenance purposes.
6. Clean the device thoroughly after use to maintain its performance and extend its lifespan.
