4. Operation and Maintenance Guide

Operating Procedure

Positive Pressure Testing

Unscrew the plug from the outlet connector and turn the fine-adjustment knob outward. Then, install the positive pressure standard gauge and the gauge under test on the two pressure output ports, respectively. Open the pressure-stabilizing valve and close the relief valve. Use the fine-adjustment knob to turn inward and increase the pressure to approximately the calibration point. Stabilize for 1–2 minutes; once the standard gauge reading stabilizes, test point by point up to full scale. After calibration is complete, relieve the pressure before removing the meter under test and the standard gauge.

If the reading slowly drops during pressurization (indicating a slight leak), close the pressure-stabilizing valve.

Negative Pressure Testing

Unscrew the plug from the outlet fitting and turn the fine-adjustment knob inward (stop when it cannot be turned further). Install the negative pressure standard gauge and the meter under test on the two pressure output ports, close the relief valve, and open the pressure-stabilizing valve. Slowly turn the fine-adjustment knob outward until it reaches approximately the calibration point, then hold it steady for 1–2 minutes. Once the reading on the standard gauge stabilizes, proceed to test each point up to full scale. After calibration is complete, open the pressure relief valve. Only after the pressure has been released may the test instrument and standard gauge be removed.

Maintenance Guide

Place the calibration bench on a flat, easily accessible surface and avoid using it in environments with highly corrosive gases or dust particles. The instrument under test should be properly cleaned to prevent contaminants from entering the test circuit.

The outlet connector is a dedicated quick-connect fitting. When installing the instrument, apply even pressure to tighten it without the need for tools. Once the sealing surfaces are in close contact, tighten it an additional 1–2 turns.

The outlet 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 come loose under high pressure.
