Cautions on the working principle of the multifunctional oscillator
The multifunctional oscillator is a kind of biochemical instrument that mixes various samples under the same environmental conditions, oscillating up and down, oscillating left and right, and oscillating oscillatingly.
Features
The multi-functional oscillator runs smoothly, has low noise, and the oscillation speed is infinitely adjustable. It adopts stainless steel spring universal fixture (custom fixture can also be customized), and can be equipped with a variety of test bottles to meet the needs of different customers. The multifunctional oscillator is the preferred equipment for research and production in industries such as biochemistry, bioengineering, teaching, microbiology and medicine.
working principle
There are mainly LC circuits composed of capacitors and inductors, which can freely oscillate during the production process through the mutual conversion of electric field energy and magnetic field energy. To maintain oscillation, an amplifier circuit with positive feedback is also required
LC oscillators are divided into transformer-coupled and three-point oscillators
Now many quartz crystal oscillators using quartz crystals [1]
There are also LC oscillators composed of integrated op amps.
Performance parameter
A new generation of multifunctional oscillators can meet a variety of experimental needs. The streamlined design of the whole machine, digital display microprocessor control, high load capacity, according to the shaking mode can be divided into track type, reciprocating type and flat plate oscillator, optional single The double-layer or double-layer shaking platform has stable operation, reliable performance and durability.

Instructions
Insert the power cord plug into the corresponding jack of the multifunctional oscillator, and then insert the three-pin plug into the power socket. At this time, the power is turned on, and if the horizontal oscillation is needed, the horizontal oscillation switch is turned on; if the vertical oscillation is needed, the vertical oscillation switch is turned on . The oscillation speed can be adjusted according to your requirements, and the oscillation speed is displayed digitally.
The panel is equipped with a power switch. When using it, first align the timer knob with the "ON" normally open position, then turn on the power switch, pay attention to the position of the timer knob, and then adjust the speed potentiometer knob according to the oscillation frequency you need . Oscillation speed digital display, you can decide the speed you want according to the displayed number. Use it at medium speed within the speed range to prolong the service life of the instrument.
Precautions
(1) The shell of the instrument should be properly grounded to avoid accidents.
(2) When not in use for a long time, the power supply should be cut off and placed in a ventilated and dry place.
(3) The instrument should be kept clean and dry, and no liquid is allowed to enter the machine.
If the instrument fails, please check the power supply first.
