5. PRECAUTIONS
To get the optimum performance from the viscometer and acquire accurate measurement data, note
the following:
5-1 General Precautions (For all models)
For accurate measurement, use care with the following conditions.
Install the viscometer in an environment where the temperature and humidity are not excessive.
The best operating temperature is 25°C ±2°C at 45-60% relative humidity.
For precise measurement, install the viscometer where there are no great changes in
temperature and humidity.
Install the viscometer where it is free of dust.
The viscometer uses the Tuning-fork Vibration Method. So, use much care to avoid external
vibration, especially when measuring low viscosity.
Places where the viscometer is prone to vibration are:
Second or higher floor, soft ground, near busy highways or rail lines.
Avoid these places as a measuring site. If measurement is to be performed in such a place, use
an anti-vibration table that is available as an option (AD-1685).
Do not measure where heaters or air conditioners can affect the measurement.
Do not measure where direct sunlight can affect the measurement.
Install the viscometer away from equipment which produces magnetic fields.
Protect the internal parts from liquid spills and excessive dust.
Do not disassemble the viscometer.
When precise measurement is required, acclimatize the viscometer to the measuring
environment. After installation, plug in the AC adapter and warm up the viscometer for one hour
or more.
5-2 Precautions for an Accurate Measurment (Only for the SV-H series)
With the SV-H series, when you need to make an accurate measurement, adjust the height of
the sample surface and sensor plates correctly by using the AX-SV-51 stand set. The
specification values are when using the stand set.
