3、 To use, first remove the stainless steel cover of the oscillator and add water to the water tank According to the experimental requirements, the amount of water added should be controlled, but at least the water level should be higher than the heating tube to prevent the heating tube from burning out. Generally, adding 2/3 of the water tank is better Adding too much water can cause water to overflow during oscillation and affect the experiment Then place the sample to be oscillated and cultured in a beaker or flask, clamp it on a spring fixture, turn on the power, close the power switch, turn on the timer to normally close "ON" or set the desired time, and the indicator light will turn on, indicating that the internal power supply has been turned on. The oscillation frequency is controlled by the speed control knob and adjusted from low speed to high speed from left to right. Set temperature: Press the SET key to set or view the temperature set point. Press the SET key once and the digital display character will start flashing, indicating that the instrument has entered the set state. Press the Δ key to increase the set value, press the ▽ key to decrease the set value. Long press the Δ key or ▽ key to quickly change the data. Press the SET key again and the instrument will return to normal working state. The temperature setting is complete. When the set temperature is lower than the ambient temperature, please turn on the cooling switch. 4、 Note 1: The instrument casing should be properly grounded to prevent accidents. 2. It is strictly prohibited for any liquid to enter the machine to avoid damaging the main unit. When not in use, the power should be cut off, the water tank should be dried and placed in a ventilated and dry place.
