Freezing water bath constant temperature oscillator

　　SHZ-82 water bath constant temperature oscillatorIntroduction:

The LC circuit mainly consists of capacitors and inductors, which oscillate freely through the mutual conversion of electric field energy and magnetic field energy. To maintain oscillation, an amplification circuit with positive feedback is also required. LC speed regulating multi-purpose oscillators are divided into transformer coupled and three-point speed regulating multi-purpose oscillators. Many quartz crystal speed regulating multi-purpose oscillators are used, and LC speed regulating multi-purpose oscillators composed of integrated operational amplifiers are also used. Due to the fact that the parameters of the device cannot be consistent, the states of the two transistors change at the moment of power on. This change, due to the increasingly strong positive feedback effect, leads to reaching a temporary steady state. During the transient state, another transistor gradually charges through a capacitor and turns on or off, causing the state to flip and reach another transient state. This creates oscillations repeatedly.

Process of using a constant temperature oscillator for a frozen water bath:

Load the test bottle and maintain balance. If it is a dual function model, set the oscillation mode.

Connect the power and set the timer according to the surface scale of the machine. If you need to work for a long time, adjust the timer to the "normally open" position.

Turn on the power switch and set the constant temperature: Place the control switch in the "Setting" section, and the temperature displayed on the screen will be the set temperature. Adjust the knob to set it to the desired temperature for your work. (The working temperature you set should be higher than the ambient temperature. At this time, the machine starts heating up and the yellow indicator light is on. Otherwise, the machine will not work); Place the control switch on the "measurement" end, and the temperature displayed on the screen will be the actual temperature of the air inside the test chamber. As the temperature inside the chamber changes, the displayed number will also change accordingly. When heated to the desired temperature, the heating will automatically stop and the green indicator light will turn on; When the heat inside the test chamber dissipates below the temperature you set, a new round of heating will begin.

Turn on the oscillation device: Turn on the oscillation switch on the control panel, and the indicator light will turn on. Adjust the oscillation speed knob to the desired oscillation frequency.

Cut off the power after work, and set the speed control knob and temperature control knob to the lowest point.

Clean the machine and keep it clean.

Water bath constant temperature oscillator

1. Please read this manual carefully before use.
2. The working surface of the machine should not be excessively smooth (such as tiles, etc.).
3. The electrical rated parameters of the socket provided by the user should not be less than the electrical rated parameters of the machine, and there should be good grounding measures.
4. The whole machine is strictly prohibited from being used in an environment with direct sunlight.
5. The speed control should start slowly from low speed to high speed.
6. The machine may experience some displacement during high-speed oscillation, so it should be monitored by someone during use.

Water bath constant temperature oscillatorInstructions for Use:

1. Add an appropriate amount of water to the water tank (the water level should be 2-3cm above the spring clamp) and place the reagent bottle on the spring clamp.

2. Firstly, turn on the power, turn on the heating switch, and the temperature controller will light up. At this time, click the SET function button on the temperature controller. Click the set function button on the temperature controller, and the upper row will display sp and the lower row will display the set temperature. Click the △ or ▽ button to select the desired working temperature. After setting, click the set function button again to enter the constant temperature timing setting. The upper row will display st and the lower row will display the set time. Click the ▲ or ▼ button to select the constant temperature timing time. (If no timing is required, set the time to 0) Click the set button again to exit the setting state. At this time, the temperature inside the box is running at a constant temperature according to the set temperature; After running, the buzzer will sound an alarm and stop heating.

3. Adjust the oscillation "timing knob", select the oscillation timing time (if timing is not required, adjust the timing knob to the normally open position), and then slowly adjust the "speed control knob" to the desired oscillation speed.

4. After use, adjust the speed control knob to the 0 position, turn off the power. If not in use for a long time, unplug the power, drain the water, clean and wipe it clean in a timely manner to extend its service life.
