Correctly select the rotor of viscometer

Correctly select the rotor or adjust the speed so that the value is between 20 and 90 cells. This type of instrument uses a dial plus pointer readings, its stability and reading bias combined together have 0.5 grids, if the reading is too small as near 5 grid, the relative error caused by more than 10%, if you choose the right rotor or speed With a reading of 50 cells, the relative error can be reduced to 1%. If the value is more than 90, the torque generated by the hairspring is too large, creep easily occurs, and the hairspring is damaged, so it is necessary to properly select the rotor and the rotation speed.
