How to maintain and upkeep the DYM3 pointer type air pressure gauge?
Date: 2025-03-17Read: 6
DYM3 pointer type empty box pressure gaugeIt is a commonly used meteorological observation instrument used to measure atmospheric pressure. Proper maintenance and upkeep are crucial to ensure the accuracy of its measurements and long-term stable operation.
1、 Daily inspection and cleaning
（1） Appearance inspection
Before use every day, the appearance of the pressure gauge should be inspected. Check if the watch case is damaged, deformed, or loose, and if the dial glass is clear and free of cracks. If damage is found on the watch case, it should be replaced or repaired in a timely manner to avoid affecting the normal operation of internal components; If there are cracks on the dial glass, it will not only affect the reading, but may also cause dust and moisture to enter the watch and damage internal components. In this case, the dial glass should be replaced immediately.
（2） Pointer check
Observe whether the pointer is flexible and free of jamming, and whether the pointer points to zero. If the pointer is stuck, it may be due to foreign objects or damage to the internal mechanical transmission components, and further inspection and cleaning are needed; If the pointer does not point to zero, gently move the pointer to zero. If it cannot be reset, the pressure gauge needs to be calibrated or repaired.
（3） Cleaning work
Regularly clean the pressure gauge by wiping the case and dial glass with a clean, soft, damp cloth to remove dust and stains from the surface. Be careful not to directly wipe the pointer and dial with a damp cloth to prevent moisture from entering the gauge. For dust inside the table, a small hair dryer or brush can be used to gently blow it away, but care should be taken to avoid damaging internal components.
2、 Regular calibration and adjustment
（1） Calibration cycle
In order to ensure the measurement accuracy of the barometer, it should be calibrated regularly.
（2） Calibration method
Calibration of a barometer requires the use of a standard barometer as a reference. Place the pressure gauge and standard pressure gauge under the same environmental conditions, and compare their readings after both readings have stabilized. If there is a deviation between the reading of the pressure gauge and the reading of the standard pressure gauge, it can be corrected by adjusting the calibration screw on the pressure gauge. When adjusting, attention should be paid to the standardization and accuracy of the operation to avoid excessive adjustment leading to increased errors.
3、 Moisture and earthquake prevention measures
（1） Moisture proof
DYM3 pointer type empty box pressure gaugeThe internal structure is relatively precise and sensitive to humidity. Therefore, during storage and use, attention should be paid to moisture prevention. The pressure gauge should be placed in a dry and ventilated environment, away from direct sunlight and damp places. If used in environments with high humidity, desiccants can be placed around the pressure gauge to absorb excess moisture.
（二）防震
During transportation and installation, the pressure gauge should be protected from severe vibrations. When transporting, handle with care to avoid collision and falling. During installation, the pressure gauge should be fixed on a stable bracket to prevent internal components from loosening or being damaged due to vibration.
4、 Other precautions
（1） Avoid using beyond the range
When using a pressure gauge, it should be ensured that the measured pressure value is within the range of the pressure gauge. Avoid using beyond the range to prevent damage to the internal components of the pressure gauge.
（2） Regularly replace the battery
For an empty box pressure gauge with electronic display function, the battery should be replaced regularly to ensure its normal operation.
