3、 Instructions for using the gas bath constant temperature oscillator:

1. TakeGas bath constant temperature oscillatorPlace it on a sturdy horizontal workbench at a distance of at least 50cm from the wall, maintaining good ventilation, heat dissipation, and a dry environment.
Before using the instrument, place the speed control knob in the minimum position and turn off the "oscillation switch".
3. Filling the culture test bottle: In order to ensure good balance performance of the instrument during operation and avoid significant vibration, the liquid filling bottles should be evenly distributed; The liquid filling volume should be roughly equal.
4. Attention: It takes 10 minutes after turning on the device to enter the cooling mode. When cooling, the temperature can be directly cooled at room temperature; If the set temperature is above 45 degrees, the compressor is in self-protection mode; Do not directly cool. When the temperature is higher than room temperature, open the lid to make the actual temperature close to room temperature. This can reduce the load on the refrigeration compressor and extend the service life of the instrument. If the set temperature is higher than room temperature, it can be heated directly.
5. Connect the external power supply (the external power cord must be grounded), turn on the power switch, and the indicator light will turn on.
6. Temperature control can be found in the temperature control manual.
7. Select the timer and adjust the timer knob to the "timer" or "normally open" position.
8. Turn on the "oscillation switch" and the indicator light will turn on. Slowly adjust the speed control knob to the desired speed. Using it at a medium speed can extend the service life of the instrument.
Before each shutdown, all switches should be placed in a non working state, set to "zero" at regular intervals, and cut off the power supply.
4Gas bath constant temperature oscillatorMaintenance：
1. Proper use and maintenance of the instrument can prolong its service life by keeping it in good working condition.
During continuous operation, the instrument should undergo regular inspections every three months; Check if any water droplets, dirt, etc. have fallen onto the motor and control components; Check fuses, control components, and fastening screws.
