When more precise measurement is required:
When the viscometer is installed for the first time or is moved to another location, plug in the
AC adapter and warm up the viscometer for one hour or more, to acclimatize the viscometer to
the measuring environment.
And before measurement, calibrate the viscometer using the sample cup that will be used for
measurement.
Placing the sensor plates and the temperature sensor in the sample may change the sample
temperature. For precise measurement, leave the sample as is for a while, after placing the
sensor plates and the temperature sensor, to ensure no changes to the sample temperature.
And then, start a measurement.
When the sensor plates and the temperature sensor are cleaned using alcohol, the plates and
the sensor are cooled temporarily and their temperature is lowered. Allow the plates and the
sensor to acclimatize to the measuring environment before measurement.
When the temperature values are not correct:
Is the display unit connected to the main unit properly using the connection cable?
Refer to "2-2 Installing the Viscometer" on page 7 to make a connection between the
display unit and the main unit.
When water viscosity is to be measured:
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.
In a measurement that takes a long time, the sample viscosity may increase due to water
contamination. Perform a periodic check on water quality.
