Operation Steps Prompt:

• Before use, check the appearance and sealing condition of the equipment to ensure that the pressure connection ports are clean.

• Connect the pressure source reliably to the instrument under calibration through the M20×1.5 interface (two ports can be used to connect the standard gauge and the instrument under calibration respectively).

• Operate the lever for coarse pressurization. After reaching close to the target pressure, use the spiral fine-tuning mechanism to slowly and finely adjust to the required pressure value.

• Observe the reading of the connected digital pressure gauge or calibrator, record the indicated value of the instrument under calibration, and complete multi-point calibration.

• After calibration, slowly release the pressure to a safe range, close the valve, disconnect the connection and properly store the equipment.

During operation, be sure to adjust the pressure slowly to avoid sudden changes that may impact internal components. It is recommended to follow the valve opening and closing sequence specified in the product user manual.
