• Turn your computer system off.
• Insert the data transmission line into the “RS232” or “PC” socket on the back panel of the RST
Rheometer.
• Connect the other end of the data transmission line with a free RS232 serial port (e.g. “COM2”) or
the USB connector of your computer.
• Turn the RST Rheometer and your computer system on again.
Caution!
Data transmission line
Use no other than the data transmission line delivered by Brookfield.
For information on the installation of the computer system, please refer to the operating instrutions of the
individual devices.
II.8 Cleaning
The paint coat of the RST Rheometer resists most solvents and weak acids. Use a dry, clean, soft and
nap-free cloth to clean the housing. Use neutral detergent liquids if necessary.
Danger!
Cleaning and Environment
Do not use chemical products such as strong solvents or strong acids to clean the housing,
especially the Touch Screen Display.
Make sure NO liquid penetrates into the housing (e.g. through the instrument connecting
sockets) and into the bearings of the measuring drive. This could destroy the instrument and
this would result in the destruction of the instrument and in the termination of implied and
express warranties!
Use the supplied cleaning cloth to clean the touchscreen and, if necessary, replace the protective foil on
the display. It is available from your Brookfield dealer.
II.9 Maintenance
The RST Rheometer system is designed for long-term operation. Should the instrument require repair,
contact Brookfield or your authorized Brookfield dealer.
Danger!
Service and Repair
Only authorized service personnel may work on the control electronics, all accessories, the
measuring device, as well as the AC Adapter and all electric circuits and connections!
Measurement accuracy can be checked by the user at any time. We recommend that the measurements
be done with Brookfield viscosity standard fluids (mineral oils) as recommended for each individual
spindle geometry.
You must:
• Use temperature control
• Select the appropriate measuring system
• Carry out measurements at the following pre-set M (‰ torque) values: 250‰, 500‰ and 750‰
• Read viscosity values from the display on the RST Rheometer
In case of instrument failure (or severe deviation from the mineral oil viscosity value), contact Brookfield or
your authorized Brookfield dealer.
