Leather is a widely used material, and its waterproof and breathable properties are important indicators for evaluating its quality.

• Step 1: adjust the movement stroke required for the test (15%, 10%, 7.5%, 5%). The eccentric must be consistent with the percentage of bit holes.

• Step 2: Turn on the power and enter the test page.

• Step 3: Use the jog button [Micro M] on the test page to move the distance between the two fixtures to the maximum position (40mm) and align at the red line.

• Step 4: Install the sample (75x60mm), the side length 60mm is the direction of 15% compression, and the side length 75mm is the clamping direction of the U-shaped fixture.

• Step 5: Insert the electrode and pour the conductive copper spring (17g).

• Step 6: Lift up the sink with a certain amount of water.

• Step7：Insert the pin to fix the position of the sink.

• Step8：the water in the sink should reach the water mark level of the fixture. Note: This is the water level mark on the fixture.

• Step 9: [Zero Ch] and [Zero Total] are used to clear data.

• Step 10: Select the station that needs to be worked, [ON] means to open this station, [OFF] means to close this station, only the [ON] state this station can work normally, [OFF] means not working.

• Step 11: Enter the setting interface, you can set the test stop condition [Stop Mode].

Start test and Result (Step 12 - Step 17)

• Step 12: Press the Start button, the bally waterproofness tester starts testing.

• Step 13: [SPD] shows the speed, all four stations are displayed in operation.

• Step14: [PV] is the set number of times, [CV] is the actual number of times. When the set number is reached, the machine will stop.

• Step15: Within the set number of times, if the sample leaks, the equipment will automatically stop.

• Step16: When the set number of times is reached, the equipment will stop automatically.

• Step17: For example, [CH.4] stops counting, which means that the sample is leaking.
