Note
When tap water is poured into the sample cup directly and is measured, bubbles are
generated on the sensor plates due to the difference in pressure and temperature and
the viscosity may increase gradually. Pressurized tap water generates bubbles easily.
Therefore, use distilled or purified water that is not pressurized.
Leave the sensor plates and sample in the same environment to acclimatize before
measuring, to decrease temperatures fluctuations.
In a measurement that takes a long time, the sample viscosity may increase due to
water contamination. Perform a periodic check on water quality.
