Usage description of ordinary pressure gauge Y-250:

1. This instrument is suitable for measuring the pressure of gases or liquids that are non corrosive, non explosive, non crystalline, and non precipitating to copper and copper alloys.
2. Before installation, the instrument must be carefully checked for model, specifications, and whether the indicator pointer is at zero position. If the model does not match or the pointer deviates from zero position, the cause should be identified and replaced or rechecked.
3. The instrument should be installed vertically and strive to maintain the same horizontal position as the pressure measuring point. Otherwise, additional errors caused by liquid level differences must be included accordingly; The length of the connecting conduit should not exceed 50M, and the ambient temperature should be between -40 ℃ and+70 ℃; Use in places where the relative humidity is not greater than 80%.
4. When measuring stable pressure, the instrument should not exceed 3/4 of the upper limit of the instrument measurement; When measuring small fluctuations in pressure, it should not exceed 2/3 of the upper limit of the instrument measurement; Low pressure should not be less than one-third of the upper limit in both cases.
5. Instruments should be regularly inspected under normal use; It is generally advisable to conduct an inspection every three months. If the instrument suddenly malfunctions (due to leakage or rupture of the spring tube causing pressure relief, pointer detachment, looseness or indication distortion, increased reading error, etc.), it must be repaired immediately and can only be used after passing the inspection.
6. If the user finds that the instrument cannot work properly due to poor manufacturing quality within 18 months after leaving the factory, under the condition of normal use and storage of the instrument according to regulations, free repair or replacement will be provided.
