How to use a viscometer, how to use a rotational viscometer:

1. Clean the rotational viscometer and adjust the two leveling feet until the blisters on the top of the rotational viscometer are in the center. (leveling)

2. Install the rotor protection frame on the rotational viscometer (rotate it to the right to install, and turn it to the left to remove it)

3. Screw the selected rotor into the connecting screw (rotate it to the left to install, and turn it to the right to remove it)

4. Plug in the power and turn on the switch button on the back of the rotational viscometer.

5. Input the selected rotor number: each time you press the rotor key, the rotor number displayed on the screen will change accordingly, until the screen displays the selected rotor number

6. Select the speed: press the "speed" key to set the speed, and press the TAB key to move to the tens, ones and tenths place of the currently displayed speed one by one. The speed of the digit, the one's digit and the tenth's place. After setting the speed, press the speed key to confirm.

7. Rotate the knob of the lifting frame to make the viscometer drop slowly, the rotor is gradually immersed in the liquid to be measured, until the mark on the rotor is level with the liquid level, and adjust the position of the viscometer to the level.

8. Press the "Measure" button, the stepper motor starts to rotate, and after a suitable time (the reading is roughly stable), the current rotor, the viscosity value at this speed and the scale of the percent meter can be measured at the same time.

9. During the measurement process, if the viscometer needs to change the rotor, you can directly press the "reset" key. (At this time, the motor stops rotating, and the viscometer is not powered). When the viscometer rotor is replaced, repeat the above 6-8 items to continue the measurement. Special attention should be paid to: after replacing the rotor of the rotational viscometer, be sure to adjust the corresponding rotor number SP on the instrument.

10. After the measurement, press the "Reset" button and turn off the power switch at the same time. Rotate the knob of the elevator to make the viscometer rise slowly, and take out the measurement sample. Remove the rotor of the rotational viscometer, and clean the rotor, instrument and test bench of the rotational viscometer.
