.7. The instrument has a data storage function, which can store up to 1000 sets of sampling data.8. The instrument has a USB interface, which can be connected to a computer for data download and analysis.9. The instrument has a LCD screen, which can display sampling time, sampling volume, battery status, etc.10. The instrument is compact and easy to carry, suitable for field sampling.IV: Structural features explanation1. Sampling head: The sampling head is made of high-quality stainless steel, which is corrosion-resistant and easy to clean. The sampling head has multiple small holes to reduce puffball superposition and reduce error of animalcule count.2. Control panel: The instrument control panel is located on the top of the instrument, which is easy to operate. The control panel includes a power switch, sampling quantity setting, data storage, and LCD screen display.3. Battery compartment: The instrument has a built-in rechargeable lithium battery, which can be used continuously for 8 hours after being fully charged. The battery compartment is located on the back of the instrument.4. Air inlet: The air inlet is located on the bottom of the instrument, which is connected to the sampling head.5. Air outlet: The air outlet is located on the top of the instrument, which is used to discharge the sampled air.V. Operation instruction1. Before sampling, check whether the instrument is fully charged and the culture dish is clean and sterile.2. Turn on the power switch and set the sampling quantity according to the actual situation.3. Connect the sampling head to the air inlet and fix the culture dish to the sampling head.4. Place the instrument in the sampling location and start sampling. During sampling, the instrument should be kept upright and stable.5. After sampling, turn off the power switch and remove the culture dish from the sampling head.6. Seal the culture dish and send it to the laboratory for analysis.VI. Maintenance and matters needing attention1. After use, the sampling head should be disinfected with 75% alcohol and dried.2. The instrument should be stored in a dry and ventilated place, and the battery should be charged regularly.3. When the instrument is not in use for a long time, the battery should be removed and stored separately.4. The instrument should be handled with care to avoid collision and damage.5. The instrument should not be used in explosive or corrosive environments.6. The instrument should be calibrated regularly to ensure accurate sampling.VII. Regular failure treatment1. The instrument does not work: Check whether the battery is fully charged and whether the power switch is turned on.2. The sampling quantity is not accurate: Check whether the sampling flow rate is consistent with the wind speed of the clean room, and whether the sampling head is blocked.3. The instrument displays abnormal data: Check whether the instrument is calibrated correctly and whether the data storage function is normal.4. The instrument has abnormal noise or vibration: Stop using the instrument immediately and contact the after-sales service for repair
