FOR SAFETY

In this manual, important safety instructions are specially marked as shown

below. To prevent the risk of injury to persons and severe damage to the unit

or peripheral equipment, make sure that all instructions are fully understood

and observed.

Caution Disregarding instructions

printed here incurs the risk of

injury to persons and/or dam-

age to peripheral equipment.

Precautions

•The No. 1 rotor and No. 2 rotor are designed for making measurements

using a JIS 300 mL beaker containing about 350 mL of sample uid. If

another container is used, the viscosity resistance working on the rotor

will be different, leading to deviations in the measurement result. If a

different container has to be used, make sure that it is considerably larger

than the JIS 300 mL beaker. In this case, the obtained measurement values

will be low.

The No. 3 rotor must be combined with the No. 3 cup, otherwise large

errors will occur in the reading.

*The actual capacity of the JIS 300 mL beaker is about 420 mL.

v

•The viscosity scale readings for the various rotor types overlap in part.

For example, the following viscosity ranges can be measured with the

following both rotors:

3 dPa•s to 13 dPa•s: No. 3 or No. 1 rotor

100 dPa•s to 150 dPa•s: No. 2 or No. 1 rotor

However, depending on the properties of the sample uid and on mechan-

ical calibration results, the obtained measurement values may be different

when changing rotors. To facilitate the correct evaluation of data, you

should therefore note the rotor number along with the measurement results.

vi

•Keep the time for one measurement under 100 seconds.

•Ambient conditions for operation of the unit are as follows:

temperature range 5°C to 35°C, relative humidity 10% to 90%RH.

•Because the drive section is not hermetically sealed, do not use the unit

in environments with volatile gas or dust pollution. Otherwise the drive

section may be damaged.

•When attaching or removing a rotor, put the viscotester in a horizontal

position and carefully move the rotor in the vertical direction. To prevent

the possibility of damage, take care not to exert strong force on the rotor

mounting shaft in the vertical or horizontal direction.

•The rotor mounting shaft is screwed into the body of the unit. Take care

not to inadvertently dislodge it when attaching or removing a rotor.

vii

•The rubber section of the rotor mounting shaft may drop out at the time of

measurement. When you want to avoid the foreign material to a sample,

remove the rubber section at the time of measurement.

•Remove the batteries from the unit when it is not being used, to prevent

the possibility of damage by leaking battery uid.

•Protect the unit from water, dust, extreme temperatures, humidity, and direct

sunlight during storage. Also keep the unit away from air with high salt or

sulphur content, gases, and stored chemicals during storage and use.

•Do not try to disassemble or alter the unit.

•Dispose of the unit and of batteries only according to national and local

regulations at the place of use.

•Do not tap the LCD panel of the unit with a pointed object such as a

pencil, screwdriver, etc.

viii

•Clean the unit only by wiping it with a soft, dry cloth or, when necessary,

with a cloth lightly moistened with water. Do not use any solvents, cleaning

alcohol or chemical cleaning agents.

•The optional stand (VA-04) is useful to stabilize the viscotester during

long-term or continuous measurements.

•To ensure continued accuracy, have the unit checked and serviced at

regular intervals. Contact the supplier.

•In case of malfunction, do not attempt any repairs. Note the condition of

the unit clearly and contact the supplier.
