1. Pull the sample holder handle on the top left of the instrument and pull to the left. Lower the sample holder. Attach the sample (according to the standard, the sample must be tested within 60 seconds after it is removed from the pre-treatment chamber) on the sample holder. If the mask shows creases, unfold the creases and fix it on the sample holder to ensure that the target area is a single layer of material. The center of the sample was taken as the test target area. Close the specimen holder. MBMTextile Testing Instruments, Testing Equipment Manufacturer

2. Press the Start button. At this time, a certain amount of synthetic blood (surface tension (0.042 ± 0.002) N/m) is sprayed horizontally onto the mask under test behind the positioning target, and the spraying starts, and the time relay starts counting at the same time, and the instrument automatically stops spraying after the set injection time.
