4. Operation and Maintenance Guide

Operating Procedure

Positive Pressure Testing

Unscrew the plugs on Outputs 1 and 2, turn the handle outward to the maximum open position, and connect the standard gauge and the gauge under test to the output ports (Outputs 1 and 2 are quick-connect fittings; no tools are required. Apply even pressure to tighten them; once the sealing surfaces are in close contact, give them one final turn). Tighten the relief valve. Turn the handwheel clockwise. When the pressure approaches the required value, use the fine-tuning mechanism to adjust it within a small range to the appropriate pressure. Only after the test is complete and the pressure has been released may the test gauge and standard gauge be removed.

Vacuum Testing

First, connect the test meter and the standard meter to the outlet ports. Turn the handle all the way down, tighten the pressure relief valve, and turn the handwheel counterclockwise. When the pressure is close to the required value, stabilize it for 1–2 minutes. Use the fine-tuning function to adjust to the test points, and test sequentially until reaching zero. Only after the test is complete and the pressure has been released may the test meter and standard meter be removed.

Precautions

4.1 Use this instrument within its rated pressure range whenever possible; do not exceed the full-scale range.

4.2 For long-term storage, keep the instrument in a dry environment free of corrosive gases.

4.3 Apply lubricating oil to the instrument’s threaded connections periodically.

4.4 During use, frequently check whether the lower locking screw is securely fastened. If the connection is loose, it may come loose under high pressure.
