Operation method

The

1.1 Select the drum according to the viscosity range of the sample to be tested. Attachment: Factor and measurement range for each drum. The factor 0.10.20.40.5 range 1 ~ 10mpa2 ~ 20mpa4 ~ 40mpa5 ~ 50mpa.

The

1.2 Zero point correction: Turn on the power switch When the motor rotates without load, gently turn the zero adjustment screw on the left side of the unit to the zero point. The zero correction during the test should be repeated three times under no load, and the zero is determined to be correct when the zero is confirmed.

The

1.3 The ends of the u-shaped spring are extended into the drum so that the hook is exposed outside the drum.

The

1.4 Carefully pour the test liquid into the test container until the liquid level reaches the lower edge of the conical surface and insert the liquid into the liquid until it is completely immersed.

The

1.5 Place the test container on the instrument tray and hang the drum hook on the hook of the rotary viscometer L-knurled screw.

The

1.6 start the motor, this time the tester can be slightly moved on the brackets back and forth, so that the drum centered (at this time there should be no vibration sound).

The

1.7 When the pointer is stable, it can be read. If the reading is less than 10, replace the bigger one.

The

1.8 Two consecutive measurements, the difference between the measured value and the average value each time must not exceed ± 3% of the average, otherwise a third determination should be made.

The

1.9 After the measurement is completed, remove the test container, clean the drum and the test container, and put it back in place.

The

2.0 Exit the zero adjustment screw, turn off the power, and fill out the "Instrument Usage Record".
