    1. INTRODUCTION This manual describes how the SV series viscometer works and how to get the most out of it in terms of performance. Read this manual thoroughly before using the viscometer and keep it at hand for future reference. 1-1 Compliance Compliance with FCC Rules Please note that this device generates, uses and can radiate radio frequency energy.

  • Page 7: Features

    Simplified calibration when measuring the viscosity near 1 mPa⋅s, (SV-10 only) Simplified calibration using purified water is a one-key operation. The SV-10 has a built-in function to measure the temperature of the purified water using the temperature sensor and calculates the viscosity value of the purified water at that temperature.

    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.

  • Page 15: During Use

    4-2 During Use To level the surface of the sample; adjust the leveling feet so that the center of the narrow part of the right and left sensor plates is on the liquid surface. The viscosity of a liquid is temperature dependent and changes by negative 2 to negative 10 percent, per degree Celsius.

  • Page 16: After Use

    4-3 After Use Remove any residual sample material from the sensor plates, temperature sensor and protector using alcohol. Using the sensor plates, temperature sensor and protector with residue of an old sample left on will cause a measurement error. Clean the sensor plates carefully to avoid bending them. The sensor plates and the temperature sensor are made of stainless steel (SUS304).
