4. PRECAUTIONS
To get the optimum performance from the viscometer and acquire accurate measurement data, note
the following:
4-1 General Precautions
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 not exposed to direct sunlight and it is not affected by heaters
or air conditioners.
Install the viscometer where it is free of dust.
Install the viscometer away from equipment which produces magnetic fields.
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).
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.
