To monitor ground safety, a proven friction and wear testing machine is needed for detection. There have been many types and designs of slip resistance testers or static friction coefficient testers in the past, but many of them are bulky. The imported static friction coefficient tester from the United States is used to quickly measure the static friction coefficient of surfaces such as tiles and stone floors to determine whether the ground or walkway is safe. It is highly useful for evaluating the slip resistance of surfaces. It is a recognized testing sensor material. II. Operating Steps:
Before operation, complete all preparations and clean the sensor thoroughly. Gently place the slip tester flat to prepare for formal testing. Connect the nylon thread chain to the end shaft of the instrument. Use two fingers to pull the thread, keeping the rest of the hand perpendicular to the hook, and ensure the thread is taut. Hook the loop of the thread with the index finger, curl the index finger to pull the slip tester, and then read the data displayed by the slip tester. Press the reset button twice and repeat the above testing method in four vertical directions until a safe value is sampled and recorded. Any abnormal, high, or low value should be discarded, and another value should be measured. The Underwriters Laboratories (UL) and the American Society for Testing and Materials jointly adopt a static friction coefficient of 0.50 or above as the recognized standard for providing a safe surface.III. Precautions: Before and after each use, regularly clean the sensor by sanding with sandpaper and brushing (cyclic testing) to prevent the accumulation of dust from the measurement surface during each measurement.IV.

Install three sensors on the instrument, complete the sanding and cleaning of the sensor foot pads, and then gently place the instrument on the surface of the test area. [Step 2]. Use the blue button on the right to select the test surface condition: Dry or Wet. [Step 3]. Press the blue button on the left (Test(+)/Calbrite) once, and a "+" symbol will appear on the left side of the screen. Press this test button twice.
[Step 4]. Take out the pulling nylon thread set, hook the S-shaped loop at one end to the pulling shaft under the instrument, and hook the other end's loop with the curled index finger. Curl the remaining four fingers into a fist and slowly straighten the nylon thread (Figure 1, 2 on the right). The control thread should be straight and horizontal. Use the middle ring and index finger, slowly curl the index finger toward the palm, and apply steady force until the instrument begins to move. At this time, observe the change in the reading on the screen. The reading at the moment the instrument moves is the static friction coefficient. The reading will stop, and this test data should be recorded. Press the test button (Test/Calbrite) twice and repeat this process to record the test.
