Five, the use matters needing attention:
Instrument should be placed in a clean, no corrosion environment, if you have special request, please indicate in the contract.
Cannot use chemical solvents such as gasoline, alcohol scrubbing panel.
Don't let the soldering iron and other heating element near the screen, this will prevent the burnt plastic resin materials.
Instrument has enough ability to overload, but do not serious overload, otherwise will cause the damage of the sensor, instrument cannot be used.
Instrument is a seismic design, but still should be carefully handled very much, especially when used at the scene, avoid the fall, a collision.
Instrument sensors are high precision products, silicon diaphragm don't collide with the solid surface, otherwise it will damage the sensor.
No professional testing skills and dedicated testing equipment, do not open the machine cover for maintenance, are not allowed to adjust the internal components and replacement material, otherwise there is no guarantee that the reliability of the instrument.
Instrument need not when, should turn off the power supply, long-term need not when, charge once three months.
Portable pressure check light with light, should be paid attention to avoid strong vibration stress check and avoid in corrosive gases or surrounding the humidity is very big, high temperature heat sources.
