Operation and Maintenance Guide

Operating Procedure

Positive Pressure Testing

Unscrew the plug from the output port, turn the fine-tuning knob counterclockwise to its outermost position, push the switch valve to the positive pressure position (push inward), install the standard gauge and the gauge under test, close the air supply valve, and use the pressure-applying rod to repeatedly apply pressure until the desired pressure is reached. If the pressure-applying rod becomes difficult to operate, use the fine-tuning knob to adjust to the desired pressure. After calibration, relieve the pressure using the air supply valve. Only after depressurization may the meter under test and the standard meter be removed.

Negative Pressure Testing

Install the negative pressure standard meter and the meter under test on the two pressure output ports, respectively. Pull the selector valve out to the negative pressure position, close the air supply valve, and use the pressure rod to repeatedly pressurize until the pressure is close to the target value. Then use the fine-tuning knob to adjust to the desired pressure. After calibration, use the air supply valve to depressurize to zero.

Precautions

Place the air pressure pump on a flat, easily accessible work surface and avoid using it in environments containing highly corrosive gases or dust particles. The instrument under test should be properly cleaned to prevent contaminants from entering the test ports.

The output connectors are specialized quick-connect fittings with face seals. When installing the instrument, no tools are required; simply tighten evenly by hand. Once the sealing surfaces are in contact, tighten an additional 1–2 turns.

The output connector consists of two parts: an upper and a lower section. During use, frequently check whether the lower locking screw is securely fastened. If the connection is unreliable, it may cause the connector to detach under high pressure.

When applying pressure with the pressure rod feels heavy, use the fine-tuning function to increase pressure gradually for easier operation.
