IV.4 Maintenance
The R/S+ Rheometer system is designed for long-term operation. Should the instrument require
repair, contact Brookfi eld or your Brookfi eld dealer.
Only authorized service personnel may work on the control
electronics, all accessories, the measuring drive, 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 Brookfi eld viscosity standard fl uids (mineral oils) as recommended
for each individual spindle geometry.
You must:
Use temperature control (i.e. water jacket and circulating bath)
Select the appropriate measuring system
Carry out measurements at the following pre-set M (‰ torque): 250‰, 500‰ and 750‰
Read viscosities from the display
In case of instrument failure (or severe deviation from the preset value), contact Brookfi eld or
your Brookfi eld Dealer.
