Operation Steps 1.The viscometer should be wiped clean by wet gauze before and after operation, dried in air or dried by air cooler. Residual liquid should not be allowed to adhere to the cup. The inner wall and outlet holes should be kept clean, and the original smoothness should be maintained for light observation. 2.Put the instrument into the barrel, when the liquid is filled, lift up vertically, and start the stopwatch at the same time. The test liquid flows out into a line. Stopwatch is stopped when it is disconnected. The time measured represents its viscosity in seconds. 3.Do the second test, the error of the second test is less than 0.5s.
