Jingda Instrument's constant temperature and humidity shaking table, as an important equipment in scientific research experiments, is widely used in fields such as plant culture, microbial fermentation, and cell research. Its precise temperature, humidity, and lighting control capabilities provide a stable and reliable environment for experiments. Proper use and regular maintenance are crucial to ensure long-term stable operation and extend the service life of the equipment. The following is an explanation from three aspects: operational standards, daily maintenance, and safety precautions.

1、 Correct usage method

1. Installation and commissioning

Placement environment: The equipment should be placed on a flat, dry, well ventilated ground, away from direct sunlight and high temperature heat sources (such as a constant temperature box), to avoid overloading the compressor. It is recommended to control the ambient temperature between 0-50 ℃ and the relative humidity between 40-93% RH.

Power connection: Use an independent power socket to ensure reliable grounding and consistent voltage with equipment identification (such as AC220V 50Hz). Before connecting, check that the power cord is not damaged and avoid operating with wet hands.

Horizontal calibration: Adjust the four foot screws of the equipment to make the whole machine in a horizontal state, preventing vibration or noise during oscillation.

2. Operation steps

Parameter settings:

Temperature: Set the target temperature (such as 25 ℃) through the controller, wait for the system to stabilize before placing the sample, to avoid overloading the compressor caused by directly placing high-temperature liquid.

Lighting: Select lighting intensity (adjustable at level 6) and cycle (adjustable from 0-99 hours) according to experimental requirements, supporting day/night mode or 99 segment program programming.

Speed: Running at medium speed (such as 230 times/minute) can extend the service life of the equipment, and it is necessary to gradually accelerate from low speed during speed regulation.

Sample placement:

Uniformly distribute the test bottles to ensure balanced load on the shaking plate and prevent liquid leakage from corroding the equipment.

Maintain appropriate intervals between test bottles to facilitate the convection of hot and cold air.

Operation monitoring:

It is strictly prohibited to put hands inside the equipment during operation to avoid electric shock or mechanical injury.

Regularly check the sealing of the box door and reduce frequent opening and closing to maintain a constant temperature effect.

2、 Daily maintenance points for the constant temperature and humidity shaking table under illumination

1. Cleaning and maintenance

External cleaning: Wipe the surface of the equipment with a soft damp cloth after each use to remove dust and residual solution.

Internal cleaning: Regularly clean the chamber and shaking plate to prevent corrosion caused by reagent spillage. The humidity control equipment needs to be heated and dehumidified every 3 months (at 40 ℃ for more than 1 hour).

Dust net cleaning: Clean the surface dust of the compressor and condenser every month to ensure heat dissipation efficiency.

2. Component inspection

Power cord: Regularly check for any damage or aging, and ensure that the plug is securely connected.

Sensor: Use a standard thermometer to calibrate the temperature display of the equipment. If the deviation is too large, contact the manufacturer for repair.

Door seal: Keep the magnetic door seal clean to prevent air leakage from affecting the insulation effect.

3. Functional testing

Compressor protection: When setting functions or turning on/off, ensure that the compressor is restarted at least 10 minutes apart to avoid damage.

Self tuning function: In balanced mode, if the temperature control is not ideal, long press the "reduce" button to start PID self-tuning.

3、 Safety precautions

1. Electrical safety

It is prohibited to replace fuses or repair circuits while they are live.

When equipment leakage, overheating, or abnormal noise is detected, immediately cut off the power and contact professional personnel.

2. Operating standards

The newly heated liquid needs to be cooled to room temperature before being placed in the equipment to prevent compressor overload.

It is strictly prohibited to move or tilt the equipment during operation (the tilt angle must be less than 45 °).

3. Emergency response

If liquid leakage occurs during the experiment, immediately shut down and clean up to avoid corrosion of the circuit.

In case of a fire, do not unplug the power plug and use a dry powder fire extinguisher to extinguish the fire.

Through standardized operation and regular maintenance, Jingda Instrument's constant temperature and humidity shaking table can maintain precise performance for a long time, providing reliable guarantee for scientific research experiments. It is recommended that the laboratory develop an equipment usage record form, track maintenance cycles, and ensure consistency of experimental data and equipment lifespan.
