Sample cup influence
The viscometers have been calibrated with the following cups when shipped. When using
another cup, use that cup to measure viscosity only after calibrating with it.
SV-1A/SV-1H Sample cup (Capacity: 2 mL)
SV-10A/SV-10H/SV-100A/SV-100H Sample cup (Capacity: 45 mL)
Note
The SV-10A/SV-10H/SV-100A/SV-100H, has been calibrated with the protector attached
when shipped. Please note that the value, obtained when the viscometer is calibrated
without the protector, may be different from that upon shipment.
14-3 When more precise measurement is required: (For all models)
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.
14-4 When the temperature values are not correct (For all models)
Is the display unit connected to the main unit properly using the connection cable?
Make a connection between the display unit and the main unit.
With the SV-A series, refer to page 12. With the SV-H series, refer to pages 14-15.
14-5 When water viscosity is to be measured (Only for SV-1A/1H/10A/10H)
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.
