To maximise the accuracy and consistency of test results, always use the same quantity of sample

for each test.

To determine the correct quantity of sample, do the following:

1. Place the sample container on the sample container support.

2. Attach the spindle to the drive head (see "Fitting the spindle" on page 8).

3. Switch on the instrument and select manual mode (see "Taking a measurement in manual

mode" on page 14).

4. Press [DOWN] until the spindle reaches the lowest position (the instrument will sound an

audible beep when the spindle reaches the lowest position).

5. Pour the sample into the container. Stop pouring when the surface of the sample reaches the

notch on the spindle shaft. If using the 600 ml glass beaker supplied with the instrument,

450 ml to 460 ml of sample will be required to reach this level.

6. Make a record of the quantity of sample used.

Whenever you conduct a test, always use this same quantity of sample. By doing this, you will be

able to perform different measurements with the same working conditions, therefore permitting

reliable comparisons between test results to be made.

The temperature of the sample has a significant effect upon its viscosity. Always check the

temperature of the sample before conducting a test. The temperature of the sample must be stable

and at the value specified in the test standard.
