3. The non-woven material sample is clamped, and the appropriate (permeable area is 5cm2, 20cm2, 38.48cm2, 50cm2 or 100cm2, etc.) clamp is selected according to the needs, and the lower clamp is first placed on the test air chamber, and then the sample Flatten it onto the lower grip, then carefully place the upper grip on the specimen, aligning the outer edges of the upper grip and the lower grip, and finally compress it with the grip.

4. Set the test parameters (system mode, time mode, constant pressure, constant flow, number of pieces and time). After the parameter setting is completed, press the "OK" key, and the system will save the setting.

5. Go back to the main interface, press the "Confirm" button or press the "Test" button, wait for 25 seconds, and then enter the test interface.
