In order to enable you to quickly and correctly master the use of this series of products, this instruction manual introduces the technical indicators, instrument composition, operating operations, precautions, etc. of this series of products in more detail. Please read the instruction manual carefully before use to permanently ensure the reliability and stability of this series of instruments.
Desktop air pressure source
It is an important auxiliary equipment in the testing of pressure instruments. It is used in conjunction with the pressure standard to complete the calibration and testing of pressure instruments.
The lever drives the piston in the large chamber to reciprocate, generating pressure or vacuum. The pressure or vacuum is output through the switch, and passes through the pressure stabilizing valve to the fine adjustment and pressure output interface. Supplemented by exquisitely designed fine-tuning, quick interface, and pressure stabilizing valve. With the advantages of simple operation, reasonable structure and good sealing performance, it can be widely used in measurement, scientific research, industrial and mining enterprises, instrument manufacturing and other industries.

.positive pressure detection
Press the switch in, unscrew the plug on the output and output connector, connect the standard meter and the tested meter, open the stable Press the valve, adjust the fine adjustment to the appropriate position (middle position), and close the air delivery valve. Operate the lever to vacuum when the pressure reaches about. Stable for ~ minutes, use fine adjustment to adjust to the calibration point, close the pressure stabilizing valve, and detect it point by point to zero.
.Under high pressure, when the pressure slowly drops, close the pressure stabilizing valve. (First fine-tune the pressure to about., stabilize the pressure for ~ minutes, and then slowly adjust to.)
, Precautions
The pressure source should be placed on a flat and easy-to-operate table to avoid entering highly corrosive materials. Used in environments with gas and dust particles.
The instrument being inspected should be properly cleaned to prevent stains from entering the detection loop.
The output and output joints are special quick connectors with end face seals.
When installing the instrument, there is no need to use any tools. Tighten evenly with force. When the sealing surfaces are close to each other, tighten ~ turns, that is Can.
The output and output connector are composed of upper and lower parts. When using, you should always check whether the lower locking screw is connected reliably. If the connection is unreliable, it may cause collapse under high pressure.
When the lever pressure is heavy, please use the fine adjustment to increase the pressure, which will be easier.
